No, as there is no way to flush the current move from the buffer and do a restart from the current position.

I have to admit that your test file did not work as expected, but after a few changes it worked better.

All I can say is the code below works on my mill and simulates OK on screen.

depends where you live, in the UK we would take it to a engineering tool makers or re-grinders.

Get the tool sharpened, it may be causing excess load on the drives and stalling them.

Hi Chris,

the tool path that you have shown is flawed, it will cut into the side of the hole on entry and exit, this is due to the fact that you are trying to apply the G41 comp into a sharp corner, this can be resolved in one of two ways you can fillet the corners with 3.2mm rads or you move the start point into the centre of one of the arcs or flats then all will work as it should.  G41 has problems but if you follow the rules it is fine and it will work with subs.

V4 uses tool compensation type C and solves all these problems but that is still some time away.
