  • Page 4: Unboxing Your New Eris® Delta 3D Printer

    1 – Unboxing your new Eris® Delta 3D Printer If you're one of the rare people that downloaded the manual BEFORE opening your new Eris®, SeeMeCNC has a treat for you! We've produced a short little video that shows how to unpack your new Eris® as well as how to load filament for the firs time! Eris®...

  • Page 5: Installing Mattercontrol

    Eris® directly – moving the axes, heating the hot end, etc. The “slicer” feature is what converts a 3D model into a form suitable for printing. We'll cover that shortly. You can download MatterControl by going to the SeeMeCNC website – http://seemecnc.com/pages/downloads. Scroll down to the “Software” heading and you'll see the links for MatterControl.
  • Page 6 Your first step will be to configure MatterControl to use the Eris®. Simply click the “Add Printer” button that's located at the top of the left MatterControl pane. When you click on the Add Printer button, you'll be presented with the dialog you see to the right.
  • Page 7 Once the installer finishes, MatterControl will attempt to automatically configure the connection. Please disconnect the Eris® and click the Continue button. Once you click on Connect, the following dialog should appear: Congrats! You're all done. Click on the Done button to continue.
  • Page 8 The configuration process automatically loads a test object that you can print. Let's take a few minutes to go over the various features of the MatterControl interface. The MatterControl interface is split into two halves. The left half is where you can load objects or G-code to print, start prints, and manually control the printer.
  • Page 9 MatterControl. 15. The Buy Materials button will open your web browser and point it to the SeeMeCNC store. 16. The Queue button opens a menu list that will allow you to export the current file and perform other operations on the print queue.

  • Page 10: Calibrating The Eris

    3 – Calibrating the Eris® Before you can start using your new Eris®, we'll need to calibrate it first. This is really easy to do! Click on the Settings & Controls button and then click on the Options button. Once you're on the Options page, click on the Show Terminal button to open up the serial console.
  • Page 11 In order to obtain the best calibration possible for your Eris®, you should also use the online calibration wizard that SeeMeCNC has created. This tool is very easy to use and includes very detailed instructions on how to use it! The calibration wizard can be found here: https://www.seemecnc.com/pages/delta-calibration-wizard...

  • Page 12: Loading And Unloading Filament

    4 – Loading and Unloading Filament Loading new filament into your Eris® is a very straightforward task. First, you'll need to feed new filament into the filament guide tube on the Eris® as shown below: Into the guide tube... Open the filament tensioner by compressing it between your thumb and forefinger, then feed the filament into the ...to the EZStruder...
  • Page 13 In MatterControl, click the LOAD FILAMENT item in the queue to make it the active job and click Print. The Eris® will begin to heat the hot end up to operating temperature and it will then finish feeding filament in and prime the hot end.

  • Page 14: First Print

    5 – First Print! Since MatterHackers was kind enough to supply us with a small calibration cube, let's make that the first print! Before your first print, make sure that the build surface is clean and free from finger prints. The oils in your fingers can cause prints to not stick sometimes. The easiest way to clean the Eris®...

  • Page 15: Mattercontrol Basics: Slicing

    6 – MatterControl Basics: Slicing MatterControl is a very complete 3D printing package and it's got a LOT of options. Some people can find this intimidating, but I assure you – there's nothing to be worried about! MatterControl is an integrated host application. This means that it provides everything needed to control the Eris®...
  • Page 16 I want you to click on the Settings & Controls button to bring up the Settings, Controls, and Options pane. Click on the SETTINGS link to make sure your display follows (by and large) what you see below. The first thing I want you to do is click on the Show Help check box that's highlighted by the arrow in the image above.
  • Page 17 Here's what the Coarse, Standard, and Fine layer heights look like when printing the little test cube. Starting from left to right, the layer heights are 0.1mm, 0.2mm and 0.3mm. You'll notice that the top layer on the 0.1mm print is kind of ratty and torn up. This is because the number of top layers is set to 3.
  • Page 18 Support Material – Support material is used when the part you're printing has free- standing features (like the chin on a bust) or another feature that requires it to be physically supported during the printing process. When you check the Support Material box, the slicer will automatically design support for the part that's currently (or will be) loaded.
  • Page 19 The image to the right should give you a pretty good idea of what the part looks like from the side. You can easily see the support material as well as the layer lines that will be at a 30 degree angle when the little cube is laid flat.
  • Page 20 Here's what you end up with after removing the support material from your part. As you can see, there's still a little clean up to to be done to the printed cube (on the left). A quick hit with some 220 grit sandpaper will knock the rough edges of the support material down. That's pretty much all there is to the Simple settings level.
  • Page 21 Click on the Simple setting drop down and pick Standard. Your MatterControl settings screen should change to something resembling the image below. Quite a number of new configuration options are accessible under the Standard settings level. The first set of options we'll tackle live under the General heading. Layers/Surface –...
  • Page 22 In the image below you can see what those perimeters actually look like on the example cube I printed. Infill - The Standard level adds Infill Type in addition to the Fill Density figure we covered before. The infill types available are Triangles, Concentric, Grid, and Lines. Examples are shown below.
  • Page 23 This can be handy when you're printing a small part and you're having bed adhesion issues and you don't want to have to use a raft. Later on in the Advanced settings section, you'll see more options on how you can tweak the Skirt and Brim settings. Support Material –...
  • Page 24 The next new category exposed under General by the Standard setting is called Filament. Under the Standard setting, the only option is Filament. This allows you to set three parameters that deal directly with the material you're currently using to print with. Diameter –...
  • Page 25 Click on that to open the preset manager. The Material Presets list shows you what pre-configured material settings you've got available to you. When you get a new roll of filament in, you can easily keep track of its settings by using this system. Click on the Add button and we'll create your first custom material! When you click on the Add...
  • Page 26 Click on the Save button to commit your changes. Congrats, you've added your first custom material profile! After you've saved your new profile, it will appear as the currently selected material as shown to the right. Now say you've printed a test cube and have decided that the print might look better if you bumped up the temperature 2 degrees.
  • Page 27 The Temperature pane contains everything you need to manually control the temperatures for both the hot end and the heated bed. MatterControl provides room for up to three temperature presets. You can edit them by clicking the pencil icon next to the Extruder Temperature label.
  • Page 28 The axis motion is controlled by the X, Y and Z labeled + and – buttons shown above. Below those four buttons are selectors indicating the step distance from 0.02mm to 100mm. The selected axis will move the selected step distance with each mouse click. For this reason, please take special care when you've got 100mm set for the step distance.

  • Page 29: Mattercontrol Basics: Loading & Printing An Object

    I'm going to chose the SeeMeCNC “Blinky” logo token (http://www.repables.com/r/118/) for my example print. You don't have to make the same choice, but pick something geometrically “simple” in order to make the learning process a bit easier.
  • Page 30 I chose the Blinky Eyes token because it's got an odd little characteristic. The model was saved using centimeters as the unit of measure instead of millimeters. This results in a model that appears to be 10 times smaller than it really is! This provides the opportunity to use MatterControl's model scaling feature.
  • Page 31 Now that you've gotten the scaling adjusted, click on the Settings & Controls button so we can make sure you're using the right profile to print this object. Click the Settings button and make sure that the Quality box is set to “Standard” and the Material box is set to the material preset you created earlier.
  • Page 32 The controls will show you how many layers are on this object as well as what the layer number is that you're currently viewing. You can navigate forward and backward through the layers by using the >> and << buttons. If you want to jump to a specific layer, you can enter it in to the box and click Go.

  • Page 33: Advanced Mattercontrol: Options

    8 – Advanced MatterControl: Options MatterControl includes a number of basic configuration options that you can use to set up things like your default slicing engine, change EEPROM settings, etc. Let's go over each one as they appear on the MatterControl Options pane. MatterControl includes a bed leveling feature that when properly configured, can assist with issues that can arise from an unlevel bed.
  • Page 34 The Gcode Terminal is where you can directly interact with the firmware on your Eris® 3D printer. When you first open the Gcode Terminal, you'll be presented with a window that looks similar to the one below: You'll notice that the display will scroll as new information comes in from the Eris®. This is how MatterControl is able to continually update things like the temperature displays.
  • Page 35 MatterControl provides the ability to remotely submit jobs or monitor your Eris® 3D printer from anywhere in the world. To learn more about the remote control feature, click on the “GO TO DASHBOARD” link and your browser will open up the MatterControl Cloud Sync website.
  • Page 36 choosing Slic3r or CuraEngine to do your slicing. Selecting a different slicing engine will change the options available on the Settings pane, but shouldn't disturb those you've changed in the past. The MatterControl team has tried to keep common names across slicing engines, so the most noticeable change you'll see will be additional options supported by one slicer but not the others.

  • Page 37: Advanced Mattercontrol: Settings - Print

    9 – Advanced MatterControl: Settings – Print MatterControl offers three “classes” of settings that have a direct effect on how your printer works. General covers elements that relate to how the plastic is laid down. Filament covers parameters specific to the type of filament that you've chosen to print with. Printer handles those remaining parameters that describe the physical printer you're currently using to print with.
  • Page 38 The first parameter is Layer Height. We've covered this one before, but I wanted to point out something that I didn't go into a lot of detail about earlier. You'll notice that the field has a yellowish highlight to it. That means that the value exists in the currently selected QUALITY profile.
  • Page 39 When Avoid Crossing Perimeters is enabled, the nozzle path will not cross a part perimeter during travel moves. This will help reduce the opportunity for stringing or oozing since the nozzle tip is rarely over open air. For instance, if the tool path would normally cause the nozzle to travel from one side of the part to the other, it would cross at least two perimeters and may leave strings of material in its wake as it moves.
  • Page 40 The next page in General is called Infill and covers how the interior of your part is filled. While I covered Fill Density and Infill Type earlier, the Advanced mode adds two new parameters. The Starting Angle parameter allows you to control the orientation of the infill. For example, an infill type of GRID with a starting angle of zero degrees is going to look like this: Now if you change the starting angle to 45 degrees, you'll end up with an infill pattern that looks like the example below.
  • Page 41 The Speed page covers parameters that control how fast various features of the object are printed. The speeds are listed in mm per second, or as a percentage of a related speed parameter. The speed parameters are pretty self-explanatory, especially if you've got the Show Help check box set.
  • Page 42 Perimeters are a great example of this. You'll note that the inside perimeter speed is 40mm/sec, while the outside perimeter is 35mm/sec. The inside perimeter will never been seen after the print is finished so it can be printed at a higher rate. However, you want the visible surface of the print to be smoother and more consistent, so you print the outside perimeters a bit more slowly.
  • Page 43 Air Gap defines how much space you want between the top surface of the raft and the bottom surface of your part. This gap helps make it easier (or even possible!) to remove the raft from your part when it's finished. As mentioned in the help text, a good air gap is one half the diameter of the nozzle.
  • Page 44 As you can see when your angle increases to 45 degrees, each layer has much less surface area to adhere to as you print. This is where support comes in handy. It provides that underlying structure for those layers to build upon. As the angle increases, the underlying surface area for each layer becomes smaller and smaller until there's simply not enough surface for the next layer to adhere to.
  • Page 45 X and Y Distance dictates how far away the support structure will be from the part you're printing. You want it as close as you can get it without it actually touching the surface of the part. The default of 1mm seems to work out pretty well. Air Gap specifies how many layers should separate the support material from the part.
  • Page 46 The Multiple Extruders page has two settings that control how ooze & filament wipes are handled. The Wipe Shield Distance specifies how far away from the part you want what is commonly known as an “ooze shield” to be placed around the part. In a two extruder system, the unselected hot end will create this “shield”...

  • Page 47: Advanced Mattercontrol: Settings - Filament

    10 – Advanced MatterControl: Settings – Filament The Filament tab allows you to change parameters that deal with the current filament you're printing with. The Filament page is divided into three categories; Filament, Temperature, and Retraction. The filament Diameter parameter tells the slicing engine the size of the material you're printing with.
  • Page 48 Retraction covers how the slicer “retracts” the filament during travel operations where it's not actually laying down plastic. Good retraction settings help keep your part free of little strings and blobs during printing. Length on Move specifies how much filament will be backed out of the hot end during a non-printing move.
  • Page 49 The next page is called Extrusion and contains a set of parameters for dealing with the width of the material as it's extruded. The First Layer parameter allows you to specify the extrusion width of the first layer. A first layer width that's larger can help with how the material adheres to the bed.

  • Page 50: Advanced Mattercontrol: Settings - Printer

    11 – Advanced MatterControl: Settings – Printer The Printer section covers items that are specific to the printer being used for the current print job. The Print Area page covers parameters that describe the mechanical features of the printer. The Bed Size fields cover the width and length of the bed.
  • Page 51 Show Reset Connection should be checked on the Eris®. It will present a “Reset Connection” button in the printer connection bar that can be used as an emergency stop. Show Firmware Updater should be set to “Simple Arduino” for the Eris®. This controls a feature that allows MatterControl to send firmware updates directly to the printer.
  • Page 52 The next page is called Custom G-code and allows you to customize the code sent for five different print events. Unless you're familiar with what the listed G and M codes do, please don't modify the defaults shown. Start G-code is inserted into the G-code output right after the temperature setting.
  • Page 53 The last feature I'd like to cover can be found here: The Options control allows you to import and export configurations. This can be handy when you want to share your slicing engine settings with others, or import settings from other sources.

  • Page 54: Using The 3D View And Layer View

    12 – Using the 3D View and Layer View The 3D View will show you the part that will be printed when you hit the Print button. The Layer View is used to inspect how your part will be printed, one layer at a time. The 3D View will allow you to view your model in pretty much any orientation you'd like.
  • Page 55 The 3D View will also allow you to directly manipulate the part or parts currently being displayed on the virtual print bed. The first control, Insert is used to add one or more components to the virtual print bed. To give you an idea of how this works in practice, head over to Repables and grab the “Ignite Michiana”...
  • Page 56 You'll end up with something similar to the figure below after clicking on Auto-Arrange. The blue arrow points to a tiny icon that indicates which is the currently selected object. In order to move an object around manually, you'll need to make sure that the “picker” icon has been selected.
  • Page 57 Cancel will discard any changes you've made so far and Save will allow you to save the state of the virtual print surface. Saving your work saves it to the print queue. Note that if you've clicked on Save, the Cancel button will retain your changes and just exit the edit mode. While you're in edit mode, there's a series of commands that become available along the right edge of the 3D View pane.
  • Page 58 The scaling operation made the cube 150% larger than the original. The X, Y, and Z fields allow you to specify exact dimensions. However, as long as the Lock Ratio field is checked, any change made to those fields will adjust the others to maintain the same ratio. The Mirror function will simply allow you to “mirror”...
  • Page 59 The Layer View is where you can see exactly what the Eris® is going to do while printing your part. When you first select it, it may show “Press 'generate' to view layers”. Click the Generate button in the lower left corner of the Layer View display. This will hand over the parts to the slicing engine and will create the G-code required to print your parts.
  • Page 60 There are two “scroll” bars shown in the Layer View. The bar along the bottom will show progress of the current layer, while the vertical bar will show layers. Using the << and >> buttons along the bottom, you can step through the layers one at a time, or jump to a specific layer and click on the Go button.
  • Page 61 Click on the Display button to the right of the display to open up those display options. Print Bed hides or displays the virtual print surface. Moves will show you the path the print head takes when it's not printing, as shown by the light green lines in the image below. Retractions show the points in the print where the extruder is going to retract filament from the hot end.

  • Page 62: A Strategy For Successful (And Great!) Prints

    Some of the links below reference part files that are stored on the forum itself. You may need to create a forum account to reach them. I highly recommend doing this whether or not you need the files. The SeeMeCNC is an excellent resource with a vibrant, helpful and very newbie-friendly community.
  • Page 63 One very easy place to do this is with the model itself. Develop your experience printing the same model over and over until you nail it. Even with a simple model, you can (and should) approach printing it with a methodical approach from the ground up. That's the next strategy. #3 Practice in Measures.
  • Page 64 It may even seem like you are getting a great first layer and great sticking (which you are) but later, you'll discover the part is nearly impossible to remove or your extruder will start making that all too familiar TICK, TICK, TICK sound from missing steps. A perfect first layer will go down smooth and consistently time after time.
  • Page 65 Recently I archived all of my H1 and H1-1 notes. I don't refer to them any longer so why keep them in my working notes? #8 Be Consistent. A CEO friend I worked with many years ago was fond of saying "Consistency is the hobgoblin of small minds!".
  • Page 66 filament need to be bumped up a bit more than 5° so don't hesitate to experiment and find that lowest reliable extrusion temperature. If you want to get really serious about profiling your filaments, do the melt-flow test at higher extrusion rates - 60 mm/s, then 70mm/s, etc. Don't forget to measure the diameter of your filament too! Not all filaments are created equally.
  • Page 67 This isn't an exhaustive list but it does include the big hitters and, as you can see, there are a few of them so it is very important to take a methodical (#2 and #8) and documented (#7) approach when solving bed-related problems. This is also a place where careful observation (#6) can play an important part.
  • Page 68 There are many other variations on this (changing slicers for example). Learn how to diagnose problems. This requires careful observation (#6). Once you've identified where the problem occurs (let's say getting the first layer to stick) then PRACTICE that piece (see #3) until you sort it out. No need to run through the entire process over and over. Isolate the problem, formulate a hypothesis on what you think might be happening and design a test to prove or disprove your hypothesis.
  • Page 69 When you do determine you have a problem that only a fan can solve, start conservatively. I also seriously recommend using a duct of some sort to focus the air flow where you need it. Ideally, the fan would have the ability to follow the print nozzle and direct a small stream of air to the filament right after it is laid down.
  • Page 70 2) first layer thickness (stop the print after first layer and measure it) 3) total print height (should be about .6mm) 4) X-Y calibration (should be 20mm diameter) 5) eliminate blobbing and other surface artifacts - follow the guide above, print slow, adjust retracts, etc. KEEP NOTES! pt3mmx20mm-cylinder.stl http://forum.seemecnc.com/download/file.php?id=8207 pt4mmx20mm-cylinder.stl http://forum.seemecnc.com/download/file.php?id=8208...
  • Page 71 Highcooley's Onyx Bed Leveling Aid is a great one to test your calibration. Highly recommended. If you can print it perfectly you've "arrived". I couldn't find a similar thing for the Eris®. If you know of one, let me know and I'll add it.
