X and Y Axis stucked

Hello guys, thanks for your answers and sorry if I disappeared (last couple of weeks been quite busy)…

Yesterday I made a check on the machine and I noticed that my build is not completely square (there is 2/3 mm error on X Axis, the Y one seems to be perfect aligned), I think that could result in stucked motor (and obviously missing steps in the software).

In these days I decided to move on a Lowrider in order to solve the problem (I will keep all the hardware I already bought and try if this solution can be more consistent) but I will give another chance to my MPCNC and I will try to make a perfect square as soon as possible.

Thank you everybody, I will write again as I get more details.
