Hi all, I have a quick question about my z screw coupler (as i understand it, the metal cylinder at the bottom you can manually move your z axis up and down with).

When I manually raise the z axis (with steppers disabled) by rotating the coupler clockwise, after I let it go, it reverses it’s rotation on it’s own and sinks back down. This is frustrating because it takes forever to actually move it any distance. Am i doing anything wrong? Should you only ever move the z axis with software, and if so, is there a way to fix the issue of it going back down? I don’t know how to adjust the tightness of this part, I’m still pretty new.

    Thanks, that’s probably the route I will take. Just wanted to know if that behavior was abnormal or not, but it sounds like it’s not too far outside the realm of people’s experiences in general

      Probably.

      FWIW with the motors unlocked I can just push on my print bed either up or down, and it’ll move. Mine just doesn’t move under its on weight. Maybe it would if it had a big model on it or something, I dunno.

      If yours is a bed-slinger gantry machine where the head moves up and down rather than the print bed, the same applies. Just in reverse.
