Hi everyone! I build my MPCNC a few months ago and it was working perfectly.
But one day it started to fail when milling. The thing is that when it starts milling, the first layer is nice, but the rest of them has a offset of almost 1 cm.
I have tried to re-flash the firmware, but it doesn’t work… I think that the error is in the communication between X and Y axis, because it cuts s square nice, but a circle doesn’t.
Consider adding some temporary thread locker (e.g. blue locktite) to the grub screws so they don’t continue to work themselves loose. The “blue” formulation doesn’t require heat to break loose but will prevent vibrations from backing the screw out again.
