Mostly-Printed Rack & Pinion XYZ machine (MPR&P)

This is a modular mostly-printed 3-axis machine made up of 3 near-identical linear stages. It is in the style of MPCNC using ¾" EMT conduit, “608” skate bearings, 5/16"(8mm) hardware, and numerous printed parts. It was built mostly from a junkbox/stash of dismantled MPCNC-inspired machines and parts… built, used, and moved several times over the years. 

A work-in-progress, the development, building, and testing of this machine is detailed in the following V1Engineering forum thread… https://forum.v1e.com/t/printed-r-p-x-y-z-platform-from-mpcnc-junkbox/48648. 

The carriage on all X and Y linear stages is near-identical and the Z-axis – while NOT identical – is similar and still R&P and seen in action in the following video…
