Thanks Nick,
I got it working by adjusting the gib until it only got stuck at on point of traveling upwards. After that I dropped the z speed a bit in the Mach 2 motor tuning and this seemed to do the trick.

It's one of those "feel" things. Make sure the gib is loose - the last moves you made should be in the upwards direction. Once you get it adjusted, try using it - don't tighten the screws further. If they end up vibrating loose then readjust and as you suggest, tighten each a tiny bit at a time. Too much will obviously throw everything off...but I found that I needed to become comfortable with the process experimentally - after a while you will sense the feel better. Also it is better too loose than too tight...
But very loose will cause other binding issues...
As I note in my setup articles, it can cause you to go insane. Once it works, leave it alone...I haven't adjusted the z-axis in months now that I have it working right... |
