Since the very beginning I irregularly have a problem with the Z axis while probing. It sometimes gets stuck when z move up and the switch does not open.
Today it happened again and I decided to see if a change of the spring #6 pressure could help.
So I loosened the SCCN8-6 collar and moved the z axis with my finger up to test the pressure and the switch. In the sticking angle position I could feel some kind of two to three "bumps" / resistance on the way up and down. Turning the pickup tube approx. 90° brought up a position where the tube moved smooth and without sensible "bumps". 90° ahead and the bumps where back.
My explanation for the bumps:
its seems to be the balls in the linear bearing! The bearing balls don't seem to like the rotation of the tube. In a normal application like a 3d printer they never rotate but always move linear along the tube.
I encountered a similar effect with my manual P&P device I constructed using linear ball bearings before I bought the Liteplacer.
Does anybody have a suggestion how to get rid of that sticking of the linear bearings? Any replacement suggestions?
