Not all M6's, and when I found the bug, there was no rhyme or reason on what actually caused the issue. The default macros worked fine, but I could get it to lock up with a single line of code in the M6 macro.
It was fixed in 3.043.028 I believe.
I've just set up all the auto tool change stuff in your screenset and it wasn't working, just sat there waiting for me to press start again without doing the move to tool change position and then the probing....just been looking into why and just come across this so will see what version of Mach I'm using.
