Wonder if anyone has any hints for this problem. I just put together my RigidBot and tried getting it to move. The X and Y axes are able to home properly but the Z axis gets stuck!.
The brass Z-nut is running up against the Z-rod connector and won't go down any further. It can't touch the bed! I thought the Z-rod connector might not be completely flush on the stepper motor, but it aint going down any further.....
Can someone pls help?
