Reduce the accelleration on xy as well. Sounds like you are loosing steps on them as well.

Help / About ....  for the version.

ok, version is vr3.042.038

x was 31,31
y was 100,40

I changed the motor tuning on both to 31,20 now

I will reload a rod in the morning and see if that helps, of course y wasn't running anyhow, but x was and I reduced the acceleration on that by 1/3

Manufacturer says speeds for x,y,z are 1500 and 200.  I'm sure that's metric. So the speeds should be 59 and 7.5 in standard. That's quite different from what I had. I will try this in the morning and see if it fixes things.  A is correct, I know that as it's at the manufacturer recommended settings and in degrees.  Say a prayer for me! lol

Wow...now, 99% sure this looks like a victory dance!  I have x,y,z at 58 and 7.5 in motor control.  Lap 2 is cutting and appears to be dead on target and all pocket jumps have 100% cleared the work piece! I suppose the summary is that the motor tuning was way too high causing missed steps.

Good Job(;-)
