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.
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.
