X-Axis Motor Mount Plate

Similar to the previous two sub-assemblies, the X-Axis Motor Mount Plate works with other components to enable linear motion. Unlike the Y-axis, the placement of the holes (used for MakerSlide) does not matter and can be reversed to suit one’s needs. They are useful for mounting terminal blocks or other small components to. Revisions to the plate designs since then have made them symmetrical and added an additional pair of holes for such uses. Note that this step uses the 55mm bolts with spacers.


Before tightening the NEMA 17 motor onto the plate, please watch this video. {{#ev:youtube|5wLiIFbf8Cg}}


Make note of a couple of things:

  • The hole orientation at the top of the plate doesn’t matter. I have mine to the left, but they can be to the right (as shown, but see note above).
  • The bottom set of bolts are the long M5 bolts (55mm)
  • When you tighten the motor into place, do so in an X pattern. You want the face of the motor to be equally pressing against the plate.
  • Don’t tighten down the V-wheel bolts. Just loosely thread on the nuts to keep everything together.
  • When you are done with the assembly, set it aside, you’ll be bolting this to the next assembly build.
