This is the seventh of eight guides in a series documenting my build of MakerGear’s Mosaic desktop FDM/FFF 3D printer kit.


This part covers installation and wiring of the electronics that control the printer. First, the Arduino and attached RAMP shield are mounted on the printer frame. Second, connections from the build platform wiring harness, the extruder wiring harness, and other components are clipped to the PCB. Finally, the power supplies are connected, and formal assembly of the printer is complete.
