Leadscrew Coupler Separating

Coupler Separating?

If you are using a “plum” type coupler, like the Upgraded Couplers we sell, and it is separating when you move your Z-Axis this is caused by binding occurring on the Z-Axis. The #1 cause of this happening is due to the eccentric nuts being too tight on the extrusion. The other cause of binding could be due to a mechanical issue like a bent leadscrew, misalignment of the coupler on the motor shaft or leadscrew, or your gantry is not properly squared up.
