Rc,
I just tried LAZCAM on another computer. ( man what a difference on a fast machine with lots of memory).I got the same error message. More than once. I didn't reboot, but changed the TOOL ANGLE to a value of 10 instead of .1 or .0001 and all was good. Then tried different  parameters and still had no problem.  Think the tool angle is the culprit. I tried the 10 value with a diamond and buttom shape seemed ok.
Need to tr it iin a more disciplined manner to really confirm.

I tried .01, .1, 1 here and in increments of 10 from 10 to 50.......wreck every time.

Here is the file.

Well now that's just LOVELY RICH.
One thing left to do.....
Please give me screenshots of EVERY dang setting....The tool selection window as well as the parameter list on the left.
I need to duplicate yours EXACTLY and try mine before I set something on FIRE !
Thanks,
RC

RC,
Both the roughing and finishing tools are the same.
