Hi all. I am having a lot of trouble with the G41/G42 cutter compensation on my plasma cutter. The kerf on the plasma cutter is 0.060", and I have it set up as tool number 1. When I enable G42, the cutter starts out ok, but goes all haywire when it reaches the circular interpolation portion of the "R" in the part. I just updated to the newest lockdown version of Mach3 thinking that would help, but it didn't. Can anyone offer any insight into why this might be happening? Here is the G-code for the part I am trying to cut out (the M1 commands are in there because I am manually starting and stopping the torch right now). Any help would be greatly appreciated. Thanks all!
