Once I had completed my MPCNC V2, 25mm version, F, (actually a rebuild of my first V1) I noticed the Z axis was off square by 1 to 2 deg. It was easily obvious to the eye. I have tried to adjust with the bolt bearing tightness but it has not cured it all. The instruction to just nip up the bolts was observed. I figure the X axis cross bar is setting too low, pulling the Z assembly down and producing the angular error.
I figure I could add a printed shim to raise the necessary cross bar on the rollers, or redesign and print new thicker spacer corners.
Anyone else noticed this?
