Question about Z screw coupler
(lemmy.world)
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.
I don't recall it ever crashing, with the printer on or off. I can test explicitly what it does when the printer is off, when my current print finishes
