Just to add my 5 cents, I have problems using NativeCAM with plasma, because NativeCAM uses tool compensation, then I can't use the digital output to enable THC. I don't see any reason why the digital I/O should be disabled if tool compensation is on Thanks Pedro Grijalva M.

Andy, With regards to M6 it seems that changing tool size might be just like starting out with cutter comp, it needs some ramp in distance to establish the cutter compensation distance and it wouldn’t know how much to apply. Alan > Date: Tue, 2 Oct 2018 12:16:54 +0100 > From: andy pugh > To:
