Do I have a bad installation
Well that's what i was kind of thinking. If you don't anything connected that would send any signals to Mach, then it should stop at that
g76 line, yes there will be simulated preliminary moves, but it should not go any further than the call for threading.
You had other versions installed before 033. So the pc could be using a wrong driver, or if you have multiple installations, it could be taking the first exe it finds....etc. I always do a computer search for any MACH.exe or sys and delete all of them the search finds and
then do a reinstall. But that's just what i do. SO could be, but i didn't want to tell you to go through a new installation and clean out the PC for no reason.
I will send you a PM and we can have a quick call and discuss.
