Hey guys. I'm having an annoying problem during a simple tool change. At the "T2 M6" line, I insert the tool into the spindle and press "cycle start". This causes the Z to slowly extend all the way down and crash the tool into my work. Mach does not seem to move beyond the "T2 M6" line. The spindle never starts or anything. I end up hitting reset but I'm assuming the Z would continue to go until it hits limits. Any ideas? Thanks in advance

After spending a good while digging around, I stepped through the M6End.m1s macro and found that it was causing the z move. I purchased this machine second hand and I suspect the previous owner edited this file. All set now.
