  • Page 13: Features And Functions

    5.1 Features and functions Important printer components and their function Extruder This printer uses a Bowden system, as previously said, in which the extruder assembly and the hotend are not work together to improve performance Extruder Assembly Element responsible for dragging the filament consists of: The Extruder Motor is responsible to power the element that drags the filament to the hotend Extruder Assembly includes pressure lever, traction spring, toothed and towing pulleys, guiding the filament and holding elements to the motor...
  • Page 14 Printing Base The surface where the extruded filament is deposited, the printed object will be formed layer- by-layer. It consists of a silicone resistor of 220v and 400w, which provides the right temperature to perform the printing with different materials. This temperature is transmitted to a 4mm aluminum surface and is controlled through a solid-state relay and a thermistor.

  • Page 15: Start Up

    6. START UP The printer will be ready to make the first impression after unpacking, so the 3DLimitless ILC printer’s surface is leveled, and the offsets (distance between the nozzle and the impression surface) are configured in the Firmware. As well as having a self-leveling system that can correct small deviations from the initial adjustments.
  • Page 16 Continue pushing the filament through the Teflon pipe till the end. Using the dial go back to Prepare in the initial menu and turn it until Move Axis, click on Advance (in this case 1mm) and press again on the dial. Next, the selection of the axis will appear on the screen and click on the Extruder Field.

  • Page 18: Computer Printing

    map of the printing base is established. An algorithm is programmed to correct any unevenness that could happen on the hotend. The printer will start the warm up of the hotend and the extruder after the self-leveling is performed. Once both temperatures are reached, it will position itself on the center to start printing.
  • Page 19 Select LANGUAGE. Click on CONTINUE to start the installation program. Accept the installation agreement of the software manufacture.
  • Page 20 Specify the folder where the program will be installed. Select the options you want to install, Uncheck the option “Repetier-server” and continue. Click Next.
  • Page 21 Create an Icon on the desktop. Click Next. The program will copy the necessary files on your computer.
  • Page 22 Once it is finished, click on End and it will open the program directly. This installation program process is similar to all Microsoft Windows applications. There can be some differences for Linux and Mac OS systems. This is the initial screen in the program, a 3D object will appear to demonstrate, that you can erase.
  • Page 23 You will enter the following data in the Connecting tab. Make sure to select the right port COM since it could be different in your computer.
  • Page 24 On the Printer tab adjust the parameters as shown:...
  • Page 25 On the Extruder tab adjust the parameters as shown:...
  • Page 26 On the Printer Dimensions tab adjust the parameters as shown: Note: The parameters dimensions are located on the printer firmware so introducing higher dimensions will have no effect on the printing surface. In the contrary, lowering the dimensions of the already specified ones will reduce the printer’s useful surface area. It is recommended not to modify the printer’s hardware specifications.
  • Page 27 The working interface consists of several zones: A 3D display that you can move with the mouse and an option zone (object, slicer, preview, manual control and SD card) are on the right. The 3D object display menus are on the left, as well as the tab to CONNECT to the printer and a FILE to load a 3D file.
  • Page 28 Proceed to configure the default CuraEngine parameters by introducing the following information on each tab, or you can click on the IMPORT tab to transfer all the printing profiles. You will find them in the CuraEngine file on this CD.

  • Page 33 Press CONNECT to start communication to the printer; if the connection is successful, it will turn green. Once connected, you can continue on MANUAL CONTROL: Slic3r is advanced slicer software with more options than CuraEngine, it also allows you to set your own printing codes.
  • Page 39 VERY IMPORTANT!!: Introduce the Start and End GCodes as detailed next and make sure you use them ALWAYS with any job, without them the self-leveling and other operations will not work correctly. In Slic3r, Start and End Gcode’s are slight different from the Cura’s gcode, as you can observe.
  • Page 40 The installation and configuration of the program is done. If you like to experiment with different values, we recommend setting new Slicer and Filament Profiles.
  • Page 41 HOW TO WORK WITH REPETIER HOST: Open the program: Home Screen: You can find more functions by going into the Repetier Host manufacturer’s manual. Download here. Select FILE which usually comes in the STL format and click on the OBJECT tab at the right corner of the screen.
  • Page 42 After the object is correctly placed, the Repetier program will show the configuration options. We’ll see each one: Coping the object When you click on it, it will ask how many copies are required. Note: If the copy will be of several different objects, they should be placed inside the blue square, as shown in the picture.
  • Page 43 Self-positioning This option will position the objects in the most optimal space. Let’s look at what happens when you click on the Self-position tab. We’ll observe that the objects are placed much closer, optimizing the time of printing by decreasing the displacements through the printing surface.
  • Page 44 Center This option will join together the center of the chosen object with the center of the printing base.
  • Page 45 Scale When you tap on this option a menu will appear: The scale will be the same on the 3 axis by keeping the lock closed. If what you want is to scale the axis differently deforming them, you need to tap on the lock. Note: Scaling can be used to reduce the original size of the objects.
  • Page 46 Rotate object When you go to Rotate option the following menu will appear: You can rotate positive or negative numbers in 360 degrees on each axis. Note: You can see the axes orientation by looking at the axes coordinates representation.
  • Page 47 You can rotate the object in different ways and forms with the axes orientation as shown in the sample: Cut viewer This option is simply to visualize the internal structure by cutting the object. See the software’s manual for more details.
  • Page 48 Mirror This option will allow you a change of the object’s orientation taking the XY plane (printing base) as reference, the sample will show the result: After revising all the different modification options that Repetier offers, you can continue with the next tab: Slicer.
  • Page 49 In this tab you will find the LAYERING options (converting the object into layers). Two layering motors are integrated in the software, the CuraEngine and Slic3R as part of the Repetier program (you can get all the details on how to configure them later in this manual). Let’s see their functions: The Drop down It allows you to choose from the two slicing motor options.
  • Page 50 Slic3R OPTIONS Cura OPTIONS When you go to CuraEngine options you This one will allow you to choose the Print can select the Printer (Printer Quality (Print Setting), the Printer (Printer Configuration), Adhesion Type giving you Settings), and the Filament Configuration two options to choose from: (Extruder I).
  • Page 51 You can tap on SLICE with CuraEngine or Slick3R after you defined the slicer motor and its parameters. The software will start the process in which it will generate the layer and the GCode necessary to print the object. The quantity and complexity of the object chosen will determent the amount of time needed for the process.
  • Page 52 The information you’ll obtain is the following: Printing Statistics Estimated Printing Time Layer Count Line Count (generated code’s total line number) Filament Needed (the necessary mm amount for the object) Display It allows you to choose the options to preview the object the way it will be done.
  • Page 53 Show Entirely Show One Layer...
  • Page 54 Show Range of Layers...
  • Page 55 Once verified the above, click on the PRINT tab and the printing will start by going automatically to the next tab MANUAL CONTROL where, as explained earlier, you can modify the parameters while printing. With the MANUAL CONTROL tab you can use the printer from the application just as the DIAL and the LCD Screen.
  • Page 56 You can find the Movement Control. The first one is for the XY Plane. The empty house icon at the bottom left corner will be used to take all axes back to zero. VERY IMPORTANT!! When you need to move any axis you must go back to zero (Home) before so the printer will know where and how much should it move.
  • Page 57 The Extruder is the last control. With this control you can push the filament with two possible speeds, one faster than the other. The retraction however will always perform in the slowest mode. The rest of the controls are at the bottom of the screen. These are the ones you can modify while the printing is going on: Printing Speed starts at 100% and you can increase or decrease it.

  • Page 58: Recommendations For Proper Use And Maintenance

    7. Recommendations for proper use and maintenance Keep the printer clean of debris from materials, especially where the shafts wheels run and fans. It can be cleaned with a dry or lightly damp microfiber cloth. When you start cleaning, the printer’s hot parts must be cold and unplugged from the electrical and USB connections as well.

  • Page 59: Printing Problems

    It is due to the Z Axis Offset been too small. The 3DLimitless ILC has preconfigured and tested all levels. If you want to modify the parameters, you would have to start a new leveling process to the printing base.

  • Page 60: First Layer Does Not Adhere To The Printing Base

    Temperature values and cooling system: When the filament is deposited on the printing base with a higher temperature difference, it will cool down faster as well causing it not to adhere correctly. 3DLimitless ILC is equipped with an electric resistance in the printing surface to add enough temperature and solve this problem.

  • Page 61: Lacking Extrusion

    Incorrect filament diameter configuration: The 3DLimitless ILC printer has an Extruder Assembly for a 1.75 mm filament diameter, for this reason you need to make sure that this is the value in the software and each of the filament profiles that you have created.
  • Page 62 For example, when you go to CuraEngine settings: Go to Print/Structures where Top/Bottom Thickness will determent the amount of upper layers. To determent the number of layers, you multiply the value of height already chosen in Quality (0.2 in this case) by the number of layers you want (4 in total in this case, it will always round it down).
  • Page 63 When you go to Slicer screen and the Printer Settings: You will see Horizontal Shells then you’ll find Solid Layers TOP You will put the desired amount The infill percentage is too low: When it happens, the upper layers support surface is small and it will cause the detachment/sinking of them.

  • Page 64: Detecting Fine Lines On The Pieces

    8.6 Detecting fine lines on the pieces Sometimes when you are printing a hollow object or the deposit of material is spaced between two points, you can see fine lines. Even thou the lines are easily removable when the printing has finished, it requires an intervention. The causes for this are: Value of the filament retraction: When the hotend is moving with no need of applying any material, the extruder motor is moving in reverse.
  • Page 65 Cura Cura Tab – Print – Extrusion – Distance Retraction Option: High Retraction Speed: It could cause bubbles inside nozzle. A regular parameter would be 40-50mm/sec, keeping in mind that it changes depending on the material’s hardness you are using. To do so, you will have to go back to the previous tabs and modify the value on Speed (Slic3R) and on Retraction Speed (CuraEngine).

  • Page 66: Excessive Heating

    8.7 Excessive heating You can see some details in the object are not well formed. Probable causes are: Insufficient Cooling: Most likely the air flow parameters for the fan are not properly set. This value depends mostly on the material used. We’ll show you where to do it. Slic3R Filament Setting Tab –...
  • Page 67 Cura Filament Tab – Cooling section Here you can adjust the minimum and maximum cooling values and the printing speed in the “Minimum Layer Time” as well, so it will not be less than the already set. The cooling percentage value is different from the previously seen and it can be adjust while printing.

  • Page 68: Marks On The Top Side

    8.8 Marks on the top side This happens when you see grooves in the filling of the upper faces. The possible causes are: Very High Extrusion Flow: Please refer to the 8.4 Over Extrusion. The effect of the hotend’s heat while moving over the already printed layers.

  • Page 69: Layers Sliding

    Cura Print Tab – Extrusion - Z Hop 8.9 Layers Sliding Some sliding could happen of the X/Y Axes while printing. The possible causes are: High Hotend Speed: If a high travel speed is set up without extrusion, it is recommended to lower it to 70%. Slic3R Print Settings Tab –...

  • Page 71: Clogged Nozzle

    Mechanical or Electronic Problems: The step-by-step adjustments of the motor controls which could have an incorrect current setting. In the case of the X/Y Axes, it may also be due to an excess or strain on the belts. If this is the case, please contact our technical support department.
  • Page 72 8.12 Spaces in the Top Layer between Perimeters and Filling There is a lack of material at the joining of the filling with the top layer perimeters. The possible causes are: Lack of Overlap between Filling and Perimeters: An overlap is always needed between the layers so the union of the two parts occurs, for this matter you have the INFILL OVERLAP Tab.
  • Page 73 Cura Print Tab – Extrusion – Infill Overlap Printing Speed of the Upper layers is too High: If this happens the upper layers will not adhere properly. You will need to configure it and reduce this value until you reach a solution to the problem. Slic3R Print Settings Tab –...

  • Page 74: Warping

    Cura This option does not exist when using other algorithms. 8.13 Warping It usually happens when you print with ABS and other materials. It is a deformation with a slight lifting of the corners due to the lack of adhesion of the first layer. Lack of Fixative (Hairspray): With ABS is required to use another fixation or adherent besides a very hot printing surface (more than...
  • Page 75 Slic3R Print Settings Tab – Skirt and Brim – Brim Width Cura Print Tab – Structure – Skirt and Brim – Brim Width Parameter, this value will define the wing size. When using CuraEngine it will be necessary adding the BRIM option on the left corner of the SLICER Dropdown.

  • Page 76: Layers Gap

    20% less than the nozzle diameter. I.E.: if you use the 3D-ILC’s 0.4 mm nozzle, the layer’s maximum height will be 0.32 mm. Nozzle can be substituted with a higher or lower...

  • Page 77: Split Filament

    Low Extrusion Temperature: If the extrusion temperature is configured too low, the cooling down will happen rapidly and the upper layer will not adhere to the previous one, even if the filament reaches a high temperature. For that reason keep always in mind the temperature range as the filament manufacture suggests.
  • Page 78 Slic3R Printer Settings Tab – Extruder – Size – Nozzle Diameter Cura You will have to go to the Repetier Host configurations to get all the values. To verify them go to Printer Settings Tab (top right side) – Extruder – Diameter Extrusion Temperature too Low: It will cause the extrusion flow to be lower and it will be harder to come out of the nozzle exerting a counter pressure that prevents the extrusion giving the “bite”...
  • Page 79 increasing the temperature between the ranges already established by the filament manufacturer. Printing Speed too high: High speed printing could have the same effect described before due to the same causes. We recommend lowering the speed parameters until the “bite” effect disappears. It can happen as well with the combination of low temperature and high speed.
  • Page 80 9. Proper Product Disposal (It means electrical and electronic equipment waste. Applicable in the European Union and in the European Countries with selective waste collection systems) If you see this symbol on the product, accessories, or any informative material that come with the equipment, it indicates that at the end of its useful life neither the product nor the electronic accessories (Extruder, cables, etc…) should be disposed of with other domestic waste.
