The liftup is still happening at the end of the cut and the corners and radius are still not right. The machine seems to running smoothly but I'm starting to wonder if I'm loosing steps some were along the way. But when I do the axis calibration test it says everything is fine.

Its not a lost steps issue, or it would not return to the same point. I tried with your xml when the look ahead was 20 and set it to 2 and the lift problem went away, starnge its not for you. I will look further at the xml and if I see anything I will post.

Cant see anything else, try running it in exact stop mode and see if it works. Just edit the code and put G61 at the end of line N20

I started dropping the FRO rates and slowly the problem went away. I'm not quite understanding this, as the rates I initially used are what worked under Mach 2 just fine, but obviously seem to be high for Mach 3. Will keep trying different rates in the motoring tuning configuration until I find something that resolves the issue .
Thanks for your help
