New Project: The MakerGear Mosaic 3D Printer – Part IV: The Z-Axis

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

  1. the frame,
  2. the Y-axis,
  3. the X-axis,
  4. the Z-axis,
  5. the extruder,
  6. the build platform,
  7. the electronics, and
  8. the first print.

This part covers assembly of the Z-axis systems, including installation of the two hardened, precision ground steel shafts that guide the build platform along its vertical path of travel, the Teflon-coated lead screw that drives it, and the stepper motor that turns the lead screw. The Z-axis limit switch is also installed at this stage.
