Thanks for sharing ideas on how to square the Z-Axis. I am having the same issue however the parts are square (thanks Ryan) but still the Z-Axis is not in the X direction only. See pictures attached.
I noticed it after I started printing real parts – not playing around.
Printed a XY part (largest volume part of a build) for a second machine and it is way off, not the biggest problem for that part however. The wires got caught on the timing belt stopping movement in one direction…
I have tried to adjust the 4 long bolts that mount the XY to the XYZ parts with decent success in the Y-direction but none in the X-direction.
Any other ideas?
Corners, height, dimensions and squareness are 100%. Rotated the tubes to have new surfaces.
