HintLightbulb.png Hint: Overview: 13" frame, first time with Titan Aero extruder; new electronics mounting; first LCD screen version; double-sided tape for bed, kapton tape bed standoffs, bed MOSFET, all 12V, 0.6 mm nozzle. Note that the production version D3D v18.06.21 went back to the Prusa i3 MK2 Extruder because of Titan Aero fan issues.

Software Notes

Change Log

  • Since we used -BY-5V part number inductive sensor - PNP - logic had to be inverted on it.
  • Changed Z_MIN_ENDSTOP_INVERTING to false in Configuration.h


Arduino Libraries

Arduino Environment


  • Control can be done from the Reprap Discount Full Graphic Smart Controller LCD or from OSE Lulzbot Cura

Arduino Uploads

  • Uploading to Arduino can be tricky.
  • First, select the right board
  • Second, select the right port
  • Possible errors: permission denied while using OSE Linux. This should not happen by default. Let's check if other linux has this issue.

avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied ioctl("TIOCMGET"): Inappropriate ioctl for device ioctl("TIOCMGET"): Inappropriate ioctl for device avrdude: ser_send(): write error: Bad file descriptor Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
