Working Principle of the 3D Printer For 3D print, first a file is needed that contains the three-dimensional data of the object to be printed (a common format of such a file is, e.g., a .stl-file). This file can be produced with the corresponding software or with a 3D-scanner. There are also many printing files already online that can be downloaded to print an object as quickly as possible. The actual printer software has the task to render the above three-dimensional file into a file that the printer can print. This is a file in which the individual print layers, the print temperatures for printing head and heating bed, etc. are specified. The file has the extension “.gcode”. This GCODE printing file is sent to the 3D printer either via the USB interface by the computer, or an SD card with the printing file is put into the card reader and the 3D printer is used in standalone operation. The 3D printer then prints the print file layer for layer according to the FFF (Fused Filament Fabrication) / FDM (Fused Deposition Modelling) procedure. At the actual print, the filament material is transported from the filament roll to the print head (extruder). In the extruder, the filament material is melted and then applied to the heating plate via a fine extruder nozzle layer by layer.

Assembly of the Mechanical Parts The following chapters refer to the assembly of the 3D printing construction kit, but are also interesting for owners of the ready- made device as information for later accessory assembly. If you have purchased the finished device, you can skip the following chapters and continue directly with the chapter “Initial commissioning”. a) General Information Take enough time for the assembly. Hurrying often leads to mistakes that may damage components or ruin the time benefit by elaborate rework. The workplace should be sufficiently large and clean so that the different components and assemblies can be put down and installed easily. The stainless steel parts of the construction kit are very sensitive to dirt. Wash your hands before installing these parts and use cotton gloves if necessary. Remove the protective film only directly before assembly. Always observe the images during assembly. Here, the assembly locations and correct alignment of the components are shown. All mechanical components of the construction kit are produced extremely precisely. Never apply any force during as- sembly. All parts can be assembled without any great application of force. If this is not the case, rethink the assembly step and reread the corresponding description in these instructions. When tightening the screws, ensure that you do not tighten them too tightly. Many screws are turned into aluminium threads and therefore must not be tightened as far as it would be possible, e.g., in steel threads. Sort the screws by size before assembly. This facilitates assembly, since you do not have to look for individual screws. For countersunk-head screws, the length (l) is measured with the screw head; for cylinder head screws, the length measurement takes place without the screw head. The diameter (d) is always measured by the thread.
Page 9: B) Assembly Of The Components
Application of the threadlocker varnish In the following instruction, some screws must be secured with threadlocker varnish. This is indicated accordingly in the text. Procedure: Put a small drop of threadlocker varnish medium-strength onto the thread start. Observe that you must only use a small drop as shown in the following screen. b) Assembly of the Components Attachment of the motor pinion to the actuators 3x actuator Push sprockets onto axes of the actuators and attach them 3x sprocket 14Z (small pinion, outer dia. 16 mm) with 2 threaded pins each.

Push the guide carriage onto the guide rail The assembly aid (plastic part in the guide of the guide carriage) must never be removed before pushing on the guide carriage, since the gearing balls will fall out of the carriage otherwise. This would be irreparable. This also applies when the guide carriage is pushed from the guide rail after assembly. For reasons of safety, the guide carriage should be secured, e.g. with adhesive tape before further installation. The guide carriage has a polished area on one side (see arrow in the figure on the lower left). Turn the guide carriage so that the arrows on the guide rails point towards the ground area of the guide carriage before pushing it on.

10. Wiring of the Electrical Components a) General Information ATTENTION Mains voltage - the connection, installation and wiring of the electrical components must only be perfor- med by an electrician who is familiar with the applicable safety provisions. Before commissioning, inspection accor- ding to the applicable safety provisions must be performed by an electrician. During the connection work, the mains line must never be connected to the mains. Drag chains The drag chains have tabs on one side of the links through which the lines are pushed into the chains. Since the drag chains can only be bent in one direction, the tab position must be observed (open on the inside > bottom in the follow- ing figure and open on the outside > top in the following figure). This is indicated when describing the individual work steps. When pushing in the lines, always push in the stronger lines first and then the thinner ones. If the tabs of the drag chains do not return to their initial position when pushed in, the tabs can be pulled back carefully with long-nosed pliers. The lines must be cleanly placed next to each other in the drag chain and must not be twisted. When clipping in the drag chain ends into already-installed drag chain end pieces, small flat pliers with which the end links of the drag chains are latched in the nipples or holes of the end pieces are helpful. Observe that the drag chain ends latch cleanly with the end pieces. Do not apply any great force, since the plastic material would be damaged otherwise and the drag chain or end piece would be rendered useless (loss of warranty/guarantee!). Lines Lines that may be swapped are marked with numbers. These numbers are placed on labels and line ends that are connected to the PCBs in the device socket. Therefore, ob- serve that the marked line ends must be placed in the device socket when placing the lines. In the Annex, you will find a wiring plan for the main PCB in which the required line connections are marked.

Page 59: C) Setup And Transport
c) Setup and Transport When setting up the 3D printer, observe that the mains switch at the low power device combination socket must be easy to reach so that the device can be switched off quickly and easily in case of malfunction. Ensure proper ventilation when setting up the device. Do not put the device down on soft supports such as a carpet or bed, etc. the air circulation also must not be impaired by other objects. This prevents heat dissipation from the product and may lead to overheating (danger of fire). When setting up the device, make sure that it has a stable footing and place it on a stable underground. Persons may be injured if the 3D printer drops. When setting up the device, make sure that the connection cables are neither pinched nor damaged by sharp edges. Always place cables so that no one can trip over them or be caught in them. There is a danger of injury. Never place the device on any valuable or sensitive furniture surfaces without sufficient protection. • Put up the 3D printer on a level, stable and non-vibration-sensitive surface. • If you want to transport the 3D printer, secure the moving parts and the heating bed with adhesive tape or cable ties. d) Mains Connection and First Activation The mains socket to which the 3D printer is connected must be close to the device and easily accessible to quickly separate the device from the mains voltage in case of an error. Do not let the mains cable come into contact with other cables. Be careful when handling mains cables and mains connections. Mains voltage may cause potentially fatal electric shock. Make sure that no cables lie around openly. Install cables professionally to prevent accidents. Before plugging in the mains plug, ensure that the device voltage indicated at the 3D printer corresponds to the availa- ble mains voltage. Do not connect the device if the indication does not correspond to the available mains voltage. Incorrect supply voltage may lead to irreparable damage to the device and danger to the user. • Plug the low power device plug of the mains line into the low power device combination socket at the rear of the device. • Plug the mains plug of the mains line into a protective contact socket. • Switch on the printer with the mains switch at the low power device combination socket (put the switch in position I). • The lighting now lights up and the display shows the welcome screen briefly. Then the main menu appears: (1) Extruder temperature (actual/target) (2) Temperature heating bed (actual/target) (3) Print plate offset in mm from the home position (4) Measured value of the print sensors at the extruder (5) Status information The target temperatures are not displayed here yet, since the extruder and heating bed are not heated yet.

The filament must not be introduced into the extruder in this case, however. It only needs to be clamped between the ball bearing and infeed knurl. If there is already some filament in the extruder, move it out with the manual filament infeed first. Caution: If the extruder has already been used, it must be heated first. Calibration should be performed now and then. It is a prerequisite for high printing quality. Perform the calibration after a transport of the 3D printer or any changes to the heating plate in any case. This calibration does not replace the correct basic setting of the limit switch for the Z-direction. It serves to balance out slight irregularities of the heating plate while printing. Ensure that the heating plate is supported levelly on the spacer bolts. Ensure that the extruder nozzle is clean on the outside. If it is contaminated, clean it as described in chapter “Mainte- nance and Care”. The figures on the display screens may vary a little depending on firmware version.

The status display of the main menu shows „Heat Bed Scan“. The geometry of the heating plate is now measured automati- cally. This process will take a while. After measurement, the heating plate returns to the home posi- tion and the display shows „Scan completed“. If the display shows „Scan aborted“, this means that measurement has been aborted. In this case, repeat the basic setting of the limit switch for the Z-direction (see chapter „Final Work“ earlier in these instructions).

Push the direction button „left“ 2x to return to the main menu. Wait until the actual temperature of the heating plate in the display shows room temperature again. f) First Print of an Example Object from the SD Card When heating, there may be slight development of smoke or steam. This is normal. Please ensure the corresponding ventilation. If you are printing with PLA filament, cover the heating plate with cleaning tape or a slightly structured crepe tape. You can find the print files on the enclosed SD card in the folder GCODE. The printing files are saved in the two folders “ABS” and “PLA” depending on the filament type used. Push the enclosed SD card into the SD card reader at the right of the 3D printer. Push OK and select „SD-Card“ with the direction buttons. If Push OK and select „Print file“ with the direction buttons. the printer was already switched on before insertion of the SD card, the option „Mount Card“ must be performed. Push OK and mark the desired file in the corresponding folder Confirm with OK. „ABS“ or „PLA“ with the direction buttons. The display returns to the main menu and the heating plate is heated. Then the axes move to the home position and the extruder is heated. Once the extruder has reached its operating temperature, printing starts.
Page 64 During the first centimetres of printing, the distance between the heating plate and extruder can be fine-adjusted manually with the buttons for heating plate movement (3). It should be approx. 0.2 mm (corresponds to about twice the paper thickness of regular 80g/m² printer paper). For this setting, observe that the extruder must not touch the heating plate since it may be damaged otherwise (loss of warranty/guarantee). The distance between the extruder and heating plate is set precisely with the software later (Z-compensation), but the manual setting is sufficient for the first prints. If no filament escapes from the extruder at first, the filament infeed button (4) must be pushed until filament escapes. Let the printed object cool off for a few minutes after printing. When the temperature of the heating plate is below 40 °C (see dis- play), the printed object comes free from the heating plate and you can remove it. Removing the SD card Push OK and select „SD-Card“ with the direction buttons. Push OK and select „Unmount Card“ with the direction but- tons. Push OK again and then remove the SD card. Push the direction button „left“ 2x to return to the main menu. The enclosed SD card holds, among others, a printing file for an alternative filament holder (file name “Filament_guide.gcode”, also see description enclosed with these instructions).

Page 69: General Notes On 3D Printing
1. General Notes on 3D Printing The print quality of 3D printers depends on a great many factors. It is not always possible to achieve a satisfactory print result at the first attempt. Extruder temperature The best extruder temperature depends on the filament material and the printer layer thickness. The manufacturer information for the printing temperature can vary very strongly here. Perform the first test prints at a temperature in the middle range of the manufacturer’s information. To optimise the print quality, print the same object with the same printing layer thickness and different extruder temperatures in 5 °C steps and then compare the results. This way you can approach the best extruder temperature for different filaments and printing layer thicknesses most easily. If the extruder temperature is set too hot, the material cannot cool off fast enough and will melt the layer below again. If the extruder temperature is too low, the filament will not become liquid enough and the filament flow is not homogeneous. The individual filament layers also cannot combine sufficiently. Heating bed temperature The best heating bed temperature also depends on the filament material. It permits perfect adhesion of the printed object to the heating plate. PLA can also be printed without a heating bed, but a temperature of approx. 60 °C has turned out to be ideal. When printing PLA (particularly at small objects with a small footprint), the heating bed should additionally be applied with clea- ning tape or a slightly structured crepe tape to increase surface adhesion. ABS needs a heating bed for printing. Otherwise it will not adhere at all or only insufficiently. Here, a temperature of approx. 160 °C should be tried out. If the heating bed temperature is too high, the printed object may distort or the lower layers will cool off too slowly. If the heating bed temperature is too low, the printed object will not adhere sufficiently or the corners will come free of the heating plate while printing. Print layer thickness The print layer thickness determines the height of the individual print layers and thus the resolution and quality of the printed objet. The thinner the printed layers, the better the print quality and the longer the print duration. The thinner the printed layers, the lower the print quality and the shorter the print duration. Experiment with the above parameters to find the best printer results for you depending on the material used. The first print attempts should be done with PLA filament, since it is a material that can be mastered relatively easily and that is subject to fewer problems with shrinkage, accuracy and adhesion on the heating plate.
Page 70: Software "Repetier Host
The enclosed SD card holds a custom version of the software that contains the printer settings and configuration files for the RF1000 in the folder “Repetier-Host”. We urgently recommend to install the custom version of the software since then you do not need to configure the software and the required drives are already installed as well.
Page 71: C) Connection Of The Connected Printer
c) Connection of the Connected Printer Start the programme Repetier-Host and select printer settings at the upper right in the window. (1) Set the port and baud rate as displayed. The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT). (2) Click “OK”.
Page 72 Click “Connect” in the upper left of the main screen of the software. After a few seconds, the symbol appears in green and the label turns to “Disconnect”. The printer has successfully been connected to the software and only some manual settings can be tested.
Page 73: D) Manual Operation Via The Software
d) Manual Operation via the Software Click the tab “Manual Control” on the main screen of the software. Before trying out manual printer control, the settings for the limit switches for the Z and Y axes must have been per- formed (see pages 31 and 5). In the finished device, this has already been performed at production but should be inspected again for reasons of safety. If this is not observed, there may be damage to the 3D printer (loss of warranty/guarantee). (1) Printer moves into the home position (2) X-axis moves into the home position (3) Y-axis moves into the home position (4) Z-axis moves into the home position (5) The arrow icons can be used to operate the corresponding axes manually. Depending on where the arrow is clicked, differently long routes are run. The route length is displayed when the mouse pointer is moved across the corresponding button of the arrow.
Page 74: E) Placement Of A Printing Object In The Software
e) Placement of a Printing Object in the Software Click the “+” symbol on the main screen of the software in the object placement tab. Select the desired file and click “OK”. The 3D object “drops” onto the printing plate in the main window. The following file types can be opened with this software: *.stl (STL-files) *.obj (OBJ-files) *.3ds (3D-Studio-files) In the folder «STL» on the enclosed SD card, you will find a few examples for the first printing attempts. However, there are already many places online where you can download 3D files (e.g. www.thingiverse.com). Alternatively, you can, of course, also use a 3D programme to make your own.
Page 75 Short description of the most important buttons in the object placement tab: (1) Adding objects (as described above) (2) Deleting the objects from the printing plate (3) Copying objects for multiple printing (in another window, the number of copies can be chosen) (4) Centring the object on the printing plate (5) “Dropping” again (this button should be pushed again before the further steps to ensure that the object is supported cleanly on the printing plate) (6) In the fields below, the object can still be moved, scaled and rotated. Use the scaling function to compensate the size retention of the printed object here as well. If it is known, e.g., that the filament material used shrinks by 2 %, set the scaling to the value 1.02 (this is an approximate reference value). After printout, you can measure the object and adjust scaling again if required.
Page 76: F) Preparation For Print
f) Preparation for Print To be able to print the object, it first needs to be sliced into individual printing layers. This process is referred to as “slicing”. Slicing of the placed printing object (1) Select suitable slicer settings for your print. The settings are always marked with the following routine: Printer_Filament material_Layer thickness_Nozzle diameter Example: RF1000_ABS300_100_05 = RF1000_3mm ABS_layer thickness 100 µm (= 0.1 mm)_nozzle diameter 0.5 mm Always use the same settings in the input fields “Print settings”, “Printer settings” and “Filament settings”. (2) Further settings can be made optionally here. However, this should only be done by experienced users. For functions, see the online help function of the software. (3) Click “Slice with Slic3r”, to slice the 3D file.
Page 77 The finished printing file appears in the graphics window after calculation. To the right of it, the G-code (layer description) appears, and below a control with which the layer view can be influenced. This layer view serves to check for errors before printing. In the very left of the screen, there is a tool bar that serves view control. For more detailed descriptions of the functions, see the online help function of the software.
Page 78: G) Printing
g) Printing The printing file produced in this manner can be printed now. There are two options for this: (1) Click “Save Job” to save the print file on an SD card and then print it out stand-alone. (2) You can also click “Start job” to send the file directly to the connected 3D printer via the USB interface of the computer and print it. Here, the log window (3) below the image shows current information on software, slicer and printer during printing.
Page 79 The graphics window may be switched to display temperature curves. There, the temperatures and their course are graphically displayed in a chart. During the first centimetres of printing, the distance between the heating plate and extruder can be manually adjusted with the buttons for heating plate movement (3). It should be approx. 0.2 mm (corresponds to about twice the paper thickness of regular 80g/m² printer paper). For this setting, observe that the extruder must not touch the heating plate since it may be damaged otherwise. The distance between the extruder and heating plate is later set precisely with the software but the manual setting is sufficient for the first print. If no filament escapes from the extruder at first, the filament infeed button (4) must be pushed until filament escapes. At PLA printing of small objects with a small footprint, it is recommended to apply the heating plate with cleaning tape or a slightly structured crepe tape before printing. Spraying the heating plate with hair spray can be helpful here as well. These measures increase adhesion of the printed object on the heating plate. Let the printed object cool off for a few minutes after printing. When the temperature of the heating plate is below 40 °C (see dis- play), the printed object comes free from the heating plate and you can remove it. If the printed object does not come loose easily, you can loosen it carefully with a painter’s spatula, knife, etc. Do not apply any mechanical force on the heating plate. Danger of heating plate breakage!
Page 80: H) More Detailed Description Of The Slicer Functions
h) More Detailed Description of the Slicer Functions Below some settings of the slicer are explained that are only to be changed by experienced users. The use of wrong settings can result in damage to the 3D printer or defective printouts. Beginners should first work with the basic settings that are integrated in the custom version in any case. If you make any changes to the settings, these must be saved in the configuration settings by clicking the disc icon. Save the different settings as a configuration setting. Assign unique names for the different configuration settings so that you can assign them uniquely to the different filament types, print resolutions, etc. later. For more information, read the integrated online help function. Click the software in the tab “Slicer” (1) to Configure (2) in the right window. The window of the slicer (3) is opened.
Page 81 Print Settings (1) Layer height (accuracy/resolution of the print object) (2) Layer height of the first layer (influences the adjustment and adhesion on the printing plate; set the first layer a little thicker than the following layers) (3) Number of outer wall layers (4) Activate for hollow bodies (e.g. vases) (5) Filled layer number top/bottom (1) Object filling (0-1 = 0-100%) (2) Filling pattern of the object and the first and last layer...
Page 82 (1) Loops are circles, that are drawn around the object when printing starts, stabilise the filament flow before the actual object is printed. Here, number, distance from the object, height and minimum length are specified. (2) Brim is a thin edge that is placed right around the object to increase the footprint and thus adhesion to the printing plate. Here, the width of the brim is specified. (1) Selection and adjustment of the supporting material that is needed when printing complex objects such as bridges or hollow spaces (poss. required for printing object with overhangs > 45°). The first printing attempts should be without a supporting brim since the result here is usually better again.
Page 83 Filament Settings (1) Filament diameter and filament diameter tolerances according to the manufacturer specification are set here. If no manufacturer’s specification is present, these values can also be measured with a calliper (measure 1 m of filament material in 10 different points and then set the average here). (2) Temperature settings for extruder and heating bed separated by first and all other layers. Observe the settings recommended by the filament manufacturer! Since the best values may fluctuate extremely depending on the filament manufacturer, perform your own tests based on the pre-settings to achieve the best printing quality. When performing the tests, proceed in 5 °C steps and compare the results during or after printing with other settings. The first layer should always be printed a little more hotly for better adhesion on the heating plate. (1) Here you can choose between automatic cooling and permanent operation of the fan at the extruder. (2) Setting of the fan speed.
Page 84 Printer Settings (1) Geometric data of the heating plate...
Page 85 (1) The starting code contains the first commands that the 3D printer performs. Here, e.g. a Z-compensation can be started. The Z compensation is unnecessary if the distance between the extruder nozzle and heating plate is set manually with the buttons of the operating fields (as described before when starting a printing process). Procedure for determination of the correct command: Move the printer to the home position. Switch off the motors and return to the main menu display. Move the extruder and the heating plate so that the extruder is placed centrally above the heating plate. Place a normal, singly folded printer paper (80 g/m²) between the extruder and heating plate. Move the heating plate with the buttons for the heating plate movement up until the paper can just be moved. A distance of approx. 0.2 mm is set here. Do not move the heating plate up too far. Danger of breaking the heating plate! Read the printing plate offset from the home position in the display (Z value in the second display line). Convert the offset read to motor steps according to the following formula: 642 x distance value = number of steps to be set Example: Your measured -0.27 mm >> 642 x (-0.27) = -173.34 steps (also about -173 steps) This means that the starting code must be moved up by 173 steps (- => up / + => down) The Z-compensation command then would be: M3000 M3004 S-173 (-173 is the number of the determined steps for the Z-motor) (2) The end code will be performed at the end of the print and could contain, e.g. the run into a removal position for the printed object. Detailed information on the G-Codes can be found, e.g., in http://reprap.org/wiki/G-code...
Page 86: Software "Cura
(1) Setting of the nozzle diameter (2) Settings for the filament withdrawal if the extruder moves to another position of the printed object during printing. If the filament was not withdrawn here, there would be drop or string formation that would negatively influence printing quality. 1. Software “Cura” a) General Notes on Software It is unfortunately not possible to explain the complete function of the “Cura” software in the scope of this instruction. We refer to the instructions and the forum under www.ultimaker.com. The basic operation and the path to the first printout are, however, described below to that you can get a result quickly and easily.
Page 87: C) Setup Of The Software
c) Setup of the Software • Connect the 3D printer to a free USB interface of the computer and switch it on. • If the printer has not been connected to the computer before, the operating system recognises new hardware and is looking for the corresponding driver. • Select manual driver selection and enter the directory. The printer driver is in a subdirectory of the directory “Arduino” on the enclosed SD card (just open the folders and subfolders in the “Arduino” directory until the directory “drivers” is displayed). • If during installation the operating system shows a message according to which the driver has not passed the Windows logo test, choose “Continue installation”. • Start the software. The “Configuration Wizard”, which will guide you through the setup process of the 3D printer, appears: (1) Click “Next”.
Page 88 (1) Select “Other” in the next window. (2) Confirm the selection with “Next” (1) Select “Custom...” in the next window. (2) Confirm the selection with “Next”...
Page 89 (1) Enter the values shown in the figure in the field on the following screen. (2) Click “Finish” to complete the wizard. The software starts and there is already an object on the printing area. (1) Click “File” (2) Select “Machine settings”...
Page 90 (1) Select the serial port to which your printer is connected. The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT). (2) Set the baud rate as shown. (3) Click “OK” to save the changes. (1) Click “File”. (2) Select “Open Profile”. Select a filament configuration file for the filament used by you in the selection window and confirm your selection. You can find the configuration file “Settings.ini” on the enclosed SD card in the folder “Cura”. Alternatively, you can skip this step. The software then uses its own basic settings that are sufficient for the first print.
Page 91: D) Use Of The Software In The Quickprint Mode
d) Use of the Software in the Quickprint Mode (1) Click “Expert”. (2) Select “Switch to quick print...” The software interface is now simplified and only very few settings need to be made before printing. This surface is ideal for producing the first test prints and familiarising yourself with the software settings and the resulting changes. In Quickprint mode, start and end G-Codes or Z-calibration are not supported. These settings are, ho- wever available in expert mode (for more information, see the instructions and the forum under www.ultimaker.com).
Page 92: E) Use Of The Software In The Expert Mode
Starting print At PLA printing of small objects with a small footprint, it is recommended to apply the heating plate with cleaning tape or a slightly structured crepe tape before printing. This increases adhesion of the printed object on the base plate. (1) Click the symbol for “Print”. (2) In the next window, click “Print”. e) Use of the Software in Expert Mode (1) Click “Expert”. (2) Select “Switch to full settings...” The software interface now has a lot more setting options. This mode should only be used by users with experience or advanced knowledge of 3D printing.

Page 94: Filament Change
17. Filament Change Before filament change, the extruder must be heated so that the old filament can be cleanly replaced from the extruder. Do not touch the hot extruder nozzle when replacing the filament, danger of burns! Always wait for the extruder temperature to be reached at filament change and let the extruder heat for approx. ano- ther minute, since the extruder may break otherwise. (1) Switch on the extruder heating. (2) Set a temperature suitable for the inserted filament material (ABS: 270 °C / PLA 230 °C). (3) When the temperature is reached, let the extruder heat for approx. another minute and then move the filament material out of the extruder with the manual control: “Extrude” moves material into the extruder, “Move in” pulls the filament from the extruder. Here, speed and length of the material that is being conveyed per mouse click can be set. After the old filament has been removed from the extruder, you can pull it out of the filament hose and insert the new filament. Then proceed as described for “Initial Commissioning”, in “Inserting the Filament” to insert the new filament. Use the manual control of the software again and let enough material extrude until the residue of the old material has completely escaped form the extruder (can be recognised by the colour change). Switch off the extruder heating again and have the extruder cool off.
Page 95: Firmware Update
18. Firmware Update The firmware is updated frequently to optimise the properties of the 3D printer. The currently installed firmware version of your printer is briefly displayed in the upper display line after switching on the printer. For firmware updates, see https://github.com/RF1000/Repetier-Firmware. Here, the most recent firmware updates are provided. You can choose between two “branches”: “Master” is the final version of the firmware. “Development” is the version of the firmware that is currently subject to development. The firmware link can also be reached in the custom software Repetier-Host under “Help” > “RF1000 Firmware”. Update process The printer must be connected to the USB interface of the computer and must not be connected to any other software (for Repetier-Host, e.g. click “Separate”). • Download the corresponding update file and save it on your computer. • Execute the file arduino.exe, which is on the enclosed SD-card (folder “Arduino” and its version subfolders until you find the file “arduino.exe”. • A window opens • In the menu “Tools”, select the option “Board” and set the type “Arduino Mega 2560 or Mega ADK”.
Page 96 • In the menu “Tools”, select the option “Serial port” and set the correct port. The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT). • In the menu “File”, choose the option “Open...” and select the file “repetier.ino” from the downloaded firmware folder. The file “repetier.ino” can be found via the following file path: “Repetier-Firmware-master\src\ArduinoAVR\Repetier”...
Page 97: Maintenance
• A new window opens. • Click “Upload” in the menu “File” here to transfer to the new firmware to the 3D printer. • After a successful firmware update, the 3D-printer will start again and briefly display the new firmware version in the first dis- play line after the start. 19. Maintenance a) General Information Periodically verify the technical safety of the 3D printer, e.g. check for damage to the mains cable and the casing. If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make sure it is not operated unintentionally. Pull the mains plug from the mains socket! It can be assumed that safe operation is no longer possible if: • the device is visibly damaged • the device no longer works • the device has been stored under unfavourable conditions for an extended period of time or • after exposure to extraordinary stress caused by transport Always observe the following safety information before cleaning or servicing the 3D printer: Live components may be exposed if covers are opened or components are removed. The device must be disconnected from all power sources before any servicing or repair work is carried out. Capacitors inside the device may still carry voltage even though they have been disconnected from all power sour- ces. Only qualified experts familiar with the hazards involved and the relevant regulations must perform repairs.
Page 98: B) Cleaning
b) Cleaning Device The outside of the 3D printer should only be cleaned with a soft, dry cloth or brush. Never use any aggressive cleaning agents or chemical solutions on plastic parts, stickers or the display since these parts would be damaged otherwise. Nozzle cleaning Caution: Danger of burns. Do not touch the hot nozzle directly. Outside cleaning of the nozzle: Carefully wipe off the extruder nozzle after each print using tissue paper or similar. The nozzle still has to be hot for this. If this is not the case, heat up the extruder nozzle first. Inner cleaning of the nozzle: Heat up the extruder and actuate the manual feed forward and backward several times until enough filament is extruded. If the extruder continues not to extrude enough material after this procedure, let the extruder cool off to the lower melt tempe- rature of the filament as indicated by the manufacturer (filament material must only be viscous anymore) and carefully confirm manual infeed backwards until the filament has been transported out of the extruder, including contamination. Cut off the conta- minated part of the filament and reinsert it after heating up the extruder again. Cleaning the heating plate Caution: Danger of burns. Let the heating plate cool off before cleaning. Clean and degrease the heating plate thoroughly with a soft rag and some acetone after each print. c) Fuse Replacement If you have to replace the fuse, ensure that you only use fuses of the specified type and rated current (see “Technical Data”) as a replacement. Never repair fuses or bridge the fuse holder. • Unplug the mains plug from the mains socket and disconnect the low-voltage line from the low power device combination so- cket at the rear of the device. • Using a suitable screwdriver to push the fuse holder out of the low power device combination socket carefully. • Remove the defective fuse and replace it with a new fuse of the indicated type. • Carefully push the fuse holder with the new fuse back into the low power device combination socket at the device. • After this, you can reconnect the device to the mains voltage and take it into operation. d) Checking the Belt Tension • Check the tension of the drive belts now and then. • If required, retention them by setting the belt tensioner with the setting screws so that the toothed belts can still be twisted by 180° easily with two fingers. The toothed belts must not be tensioned too strongly. If a belt tensioner bends, the belt tension must be reduced under all circumstances.
Page 99 Method for precise setting of the belt tension For this, you need a weight of 1 kg, such as a water bottle filled with water to reach the specified weight of 1 kg. You also need a cord for attachment. Fasten the heating plate with adhesive tape or similar first to keep it from falling out and being damaged if the printer tips. Place a soft support under the printer so that it is not scratched when tipping and so that it cannot damage the table top. Now tip the printer to its front near the edge of the table and Measure the distance between the two toothed belt halves as attach the weight to the part of the toothed belt for the X-direc- shown in the figure. Set a distance of 28 mm with the belt ten- tion that is now at the bottom using the cord. sioner. The weight must be suspended so that it can move freely. Now tip the printer to the right side near the edge of the table Measure the distance between the two toothed belt halves as and attach the weight to the part of the toothed belt for the Y- shown in the figure. Set a distance of 30 mm with the belt ten- direction that is now at the bottom using the cord. sioner. The weight must be suspended so that it can move freely. For this, it must be threaded through an opening in the side part near the right threaded circulation spindle.
Page 100 Now tip the printer to its rear near the edge of the table and Measure the distance between the two toothed belt halves as attach the weight to the part of the toothed belt for the Z-direc- shown in the figure. Set a distance of 41 mm with the belt ten- tion that is now at the top using the cord. sioner. The weight must be suspended to be freely movable but may touch the mains unit housing. This is not a problem.
Page 101: E) Nozzle Change
e) Nozzle Change Caution: Danger of burns. Do not touch the hot nozzle or the extruder directly. • To replace the extruder nozzle, the extruder must first be heated to a temperature suitable for the inserted filament material. • When the temperature is reached, remove the inserted filament material as described in “Filament Change”. • Screw off the extruder nozzle (1) from the extruder with a 10 mm hexagon wrench (2). Always secure the extruder against twi- sting at the flattened area of the nozzle thread above the nozzle with the enclosed nozzle wrench (3). The extruder must not twist during nozzle change and the nozzle must never be turned when cold since the cement layer above the nozzle may break otherwise. This will render the extruder useless. • Clean the thread at the extruder of filament residue (e.g. with a brass brush). • Coil a piece of sealing tape of about 5 cm around the nozzle thread at the extruder and carefully screw the new nozzle onto the extruder. Secure the extruder against twisting again with the enclosed nozzle wrench. Do not wrap the sealing tape beyond the nozzle thread since the nozzle will clog otherwise. We recommend our PTFE high-temperature tape from the accessory programme of the 3D printer. • Carefully screw in the new extruder nozzle. Never apply any strong forces for this. • Then insert the filament again as described in “Filament Change”. • Switch off the extruder heating again and have the extruder cool off. 0. Handling • Never connect the mains plug to a mains socket immediately after the device has been taken from a cold to a warm environ- ment. The resulting condensation may destroy the device. Allow the device to reach room temperature before connecting it. Wait until the condensation has evaporated. • Never pull the mains plug from the mains socket by the cable. Only pull it from the mains socket by the intended grip areas. • Disconnect the 3D printer from the mains voltage if you are not going to use it for an extended period of time. • Disconnect the mains plug from the mains socket during thunderstorms for reasons of safety. • The heating plate and extruder may heat up strongly in operation. Do not touch these parts during or just after operation. Let these parts cool off first.
Page 102: Troubleshooting
1. Troubleshooting With this 3D printer, you have purchased a product that is built to the state of the art and operationally safe. Nevertheless, problems or errors may occur. Therefore, we would like to describe how to eliminate possible errors here: Always observe the safety information! The 3D printer does not work after switching on. The display and print space lighting remain dark: • Check the connection of the mains line. • Check the mains socket. Is it properly supplied with current? • Check the mains fuse (also see “Fuse change” in chapter “Maintenance”). No USB connection to the 3D printer is possible: • Check the USB line connection. • Is the right USB port selected in the software? • Are the required drivers installed? • Unplug the USB line and then plug it in again. • Start the software again. • Switch the 3D printer off and on again. • Start the computer again. • Use another USB port. • Connect the 3D printer directly to a USB port of the computer. Do not use any USB hub. Calibration of the heating plate stops. The display shows the message “Scan aborted”: • Heat the extruder to melting temperature of the inserted filament and transport the filament a few steps backwards out of the extruder. The filament must not cause any forces to be exerted on the extruder but the ball bearing holder still must be loaded by the filament. • The extruder nozzle must be clean from the outside (if required, heat and wipe off first – caution: hot nozzle!) • Perform the basic settings of the limit switch for the Z-direction again. The plate distance must not be too large. • The pressure sensors may have been installed under tension. In this case, loosen the screws of the print sensors and then retighten them evenly.
Page 103 The filament supply breaks off or there is not enough filament material supplied: • Check the filament unroller. It must turn easily. • Check whether the filament material has caught on the filament unroller. The filament hose at the filament roller may have caught. • Some filament types do not slide through the filament hose properly. If required, use the alternative filament holder that you can print from the SD card (file name “Filament_guide.gcode”). • The set extruder temperature is too low for the filament material used. The feed knurl slips at the filament material. • Check whether the feed knurl slips on the motor axis of the extruder motor. The grub screw may have come loose. If the feed knurl slips in spite of the grub screw being tightened, use a grub screw with a point or slightly file down the motor axis in the area of the grub screw to reduce slippage. • The clamping spring screws at the filament feed are not tightened well enough. Therefore, the drive slips. • Check that the filament material runs into the extruder from above cleanly. It must be able to run past the extruder motor from above and into the bore of the extruder without scraping or clamping anywhere. If this is not the case, loosen the nut at the extruder and the screws at the feed basic part and align the parts so that the filament is cleanly inserted into the extruder. • The extruder nozzle is clogged. Heat up the extruder and actuate the manual feed forward and backward several times until enough filament is extruded.

Page 106: B) Notes On The Print Files (Gcode Files) On The Enclosed Sd Card
The folder “GCODE” on the enclosed SD card holds various finished printing files. These files do not need to be sliced with a software like the Repetier-Host first. They can be printed right from the SD card (also see “First Print of an Example Object from the SD Card”). The files are saved in the folder “ABS” and “PLA”, depending on the filament type used. Example: Heart.gcode in the folder ABS = small heart for printing with ABS filament c) Setup of the Printer Settings This chapter is only targeted at users who do not have the custom version of the software installed. If you have instal- led the custom version (can be recognised by the image of the RF1000 3D-printer when the programme starts), you may skip this chapter. It only serves information purposes then. Start the programme Repetier-Host and select printer settings at the upper right in the window.
Page 107 (1) Name your printer RF1000_3D in the following window in tab “Connection” or assign a name of your own. (2) Set the port and baud rate as displayed. The port number is system-dependent. You can find it in the device manager of the control panel, under connections (COM and LPT). (3) Set the receiver cache size as shown. (4) Click “Accept”. Click the tab “Printer”. Transfer the settings 1:1 as shown in the following figure and click “Accept”.
Page 108 Click the tab “Printer form”. Transfer the settings 1:1 as shown in the following figure and click “Accept”. No settings are necessary in the tab “Advanced”. Click “OK”.
Page 109: D) Explanation On The Configuration Files On The Enclosed Sd Card
This chapter is only targeted at users who do not have the custom version of the software installed. If you have instal- led the custom version (can be recognised by the image of the RF1000 3D-printer when the programme starts), you may skip this chapter. It only serves information purposes then. The folder “Slic3r Settings” on the enclosed SD-card contains different configuration files (.ini-files) for the basic version of the software Repetier-Host. If you have installed the custom version adjusted for the RF1000 of the Repetier-Host software, configuration files are already integrated into the software. The files are designated as follows: Printer name_Filament material_Layer thickness_Nozzle diameter.ini Example: RF1000_ABS300_100_05.ini = Printer RF1000_Filament 3mm ABS_Layer thickness 100 µm (=0.1 mm)_Nozzle Diameter 0.5 mm The option VASE permits printing of objects with filling (e.g. cylinder) as hollow bodies without having to produce the corresponding 3D file for it. If a cylinder-shaped body is printed with the option VASE, the resulting object has a bottom plate and a thin outer wall (like a vase). e) Setting up the Slicer This chapter is only targeted at users who do not have the custom version of the software installed. If you have instal- led the custom version (can be recognised by the image of the RF1000 3D-printer when the programme starts), you can ignore this chapter. It only serves information purposes then. Click the tab “Slicer”. (1) In “Slicer”, select the programme “Slic3r”. (2) Click “Configure” to set up the programme on the 3D-printer.
