ArtEngine MakerBot

Getting started with the ArtEngine MakerBot.

Where it lives

In a cupboard in the M70 lab.

Setting Up

The Mac Mini

  • Hook up the small LCD panel
  • Hook up the keyboard and trackpad or mouse
  • Power it up

The MakerBot

  • Plug in the power supply
  • Plug the USB cable into the Mac Mini
  • Turn on the MakerBot PSU (back of the bot)
  • Turn on the MakerBot motherboard (small black slider switch on the largest side board)

Preparing to Print

Launch ReplicatorG

This is your main point of interaction with the MakerBot.

Open Your Model

  1. Pick File - Open...
  2. Click the Scale button to view the scale operations. If your model is much larger or much smaller than expected. STL is unit-less and some programs export in 1 unit = 1 inch instead of the expected 1 unit = 1 mm.
  3. Click the Move button to view the object reposition operations.
    1. Click Center to position the object at Z=0 on the build platform.
  4. Click Generate GCode
    1. Pick a printing profile: artengine-abs-0908
    2. Enable the Use raft checkbox.
    3. Click Ok

Warm Up the Extruder

  1. Pick Machine - Control Panel
  2. Set the Target Temperature to 220.0
  3. Click outside the field to engage the heater. You should see the blue line jump to 220C and the red line start to rise.
  4. Wait until the Current Temperature reaches the target temperature.
  5. Set the Motor Speed (PWM) to 255.
  6. Click the Motor Control - forward button. The extruder motor should start to turn.
  7. Cut the filament flat with the cross-cutters and feed the filament into the top of the extruder.
  8. When the small noodle of extruded plastic starts to come out fast (not just oozing out), click Motor Control - stop

Prepare to Print

  1. Centre the build platform and extruder
    1. Manually (with your hands!) slide the XY build platform to the center position
    2. Pull on the Z axis belt to position the extruder nozzle tip (gently!) in contact with the centre of the build platform.
  2. Upload the GCode to the MakerBot's onboard SD card.
    1. Use the SD card reader for fast transfers.
    2. USB direct in a pinch.
  3. Pick Machine - Control Panel
    1. Raise the extruder by 10mm by clicking the Z+ button.
    2. Set the Target Temperature to 220.0
    3. Wait until the Current Temperature reaches the target temperature.
    4. Set the Motor Speed (PWM) to 255.
    5. Click the Motor Control - forward button. The extruder motor should start to turn.
    6. When the small noodle of extruded plastic starts to come out fast (not just oozing out), click Motor Control - stop
  4. From the Control Panel, send the extruder back to Z=0 by clicking the Z- button.

Print!

  • Print from the SD card for big objects.
    • Don't bother printing directly unless the objects are small and not very complicated or the USB2TTL link will saturate and Strange Things will happen.
