I am having problems with holes in the Z axis. They are oblong. I wanted to adjust the Z belts to make sure they are all the same tension to see if this is the problem. It’s both the top and bottom, so not an overhang issue.
I got three of the 4 to be equal at 150hz no problem. But the 4th is about 220hz and I can’t adjust it lower. I have it all the way out and it’s still too tight. Is there another adjustment somewhere? I’m adjusting the top of the belt. Do I have to disassemble and adjust something at the bottom?
