MPCNC dual endstop squaring tool.

My MPCNC uses dual endstops for auto squaring. Calibrating the positions of the endstops exactly was proving to be a challenge so I made these gauges to simplify the task.
You can use the markings on the tool for coarse adjustment or use a caliper for finer adjustment.
This tool removes any inaccuracies caused by measuring from the tower tops

It does assume that your frame is 100% square to begin with of course.

You will need to print 2 of each part for the tubing size you use (23.5mm, 25mm, or 25.4mm).
