I have been working with my MPCNC for a few months. everything seemed to be running ok so I started cutting some simple shapes. I am finding that parts are ending up thinner in the Y dimension than they should be, X seems better and Z seems about right. I am also finding that it seems to be cutting some corners and angles short.
In trying to trouble shoot I checked for play in various parts to see if that was at issue. I am not finding much play but I do find that when not moving one of the x and one of the y motors seem engaged and holding their position while one for each axis seems to move freely from the position it was moved to. The motors are turning but should all four motors be holding their position and resist movement?
