Prompted by a forum thread: https://forum.linuxcnc.org/20-g-code/37542-strange-behaviour-m61-qn-and-cuttercompensation
I have done some experiments in sim/axis/axis-mm using the sample g-code (included below) With M6 T2 enabled (about half way through) it's all fine With M61 Q2 the code _runs_ OK but gives a warning message when the file is reloaded. (And with M61 Q12, it correctly gives an error on loading, and on running) Testing with tklinuxcnc, no error except in the M61 Q12 case, when there really is an error. So my conclusion is that the file-check on loading in Axis is to blame. In what way might that handle M61 differently to the way that the actual machining process does? ; Testfile for M61 Q2 and cuttercompensation problem. In Tooltable Tool T12 D=12 and Tool T2 D=2 required.
