I have assembled my MPCNC very secure. Everything has the right dimensions, is rectangular and running smooth without backlash. Only one problem, the Z-axis in one direction is not 100% perpendicular with the table, its hanging a bit (about 2 mm) skew in the middle assembly, see the pictures.
Played with the tension of the bolts, but that doesn’t help. Anyone an idea/suggestion what I can do more?
