why am i getting a kink as highlighted below? its not in the coding and not in the blue line, its just in the white line for the g41 command? but actually gets machined into the material

I would say it is a GLITCH in the TC code.  IF you run the code in reverse motion as in a conventional cut it will probably work ok.

Just a thought, (;-)TP

bugger, is there a way of reporting bugs in mach3?

Support@MachSupport.com

Just for what it is worth Mach3 is at the END of it development life.  I would not expect much more to be done to it before Mach4 comes out.

Just a thought, (;-) TP

These G41/G42 bugs are well known and have always existed. As Terry says, all you can really do is wait until Mach4 is out, sometime later this year.
I use comp all the time, and rarely see any issues like this, but when I do, I just don't use comp for that particular part.

Playing around with it here I can make it better but not perfect using your code snippet.

Can you post the complete file ?
