I have been getting some inconsistent cutting depths lately. I took the Z motor cover off and watched the coupler while the machine was cutting a long flat straight profile and saw the coupler slightly turn. So I believe I have traced the problem to the Z axis coupler screw that attaches to the Z motor. When I first got the machine I managed to strip the screw head when tightening it down. Now I can't tighten or loosen it.
I already ordered more couplers but in the meantime I have some hard deadlines and need the coupler fixed yesterday.
I'm planning on getting a screw extractor and replacing the set screw. I don't want to mess up any of the other coupler screws by removing them.
So I thought I would ask if anyone knew the size of the screw so I could get a replacement? Thanks
