CNC machine cutting incorrect dimensions

[Neale]

Have you tried changing tool size defined in HSMexpress to see what happens? You mentioned that you had changed tool size in Mach3.

Yes I have. In Mach 3, the tool size change doesn't affect the cut. Changing the tool size in HSMexpress changes the code accordingly.
But as the deviation from the dimensions is not constant, I can't just define a larger tool - that then messes up other areas if you know what I mean...
