Please let me know if you have any ideas about what's going on here.... I have a home made 3 axis cnc router using probotix and gecko electronics/steppers, etc. This has worked to some extent although I've had a few electronics problems that have been cured, I think. Things seem to run ok in manual jog mode but now when I run a g code program Mach 3 will flash the z axis limit switch line on the diagnostics page (just a blip) and tell me I've hit a limit switch. This happens in random areas, usually once per program. And during the time that the machine is waiting to be reset and the program restarted, it jumps code (a varying number of lines), so I can't finish a program unless I reset the line pointer. Here's the kicker, it does this even when it's in demo mode and the electronics are shut off.... What th'??
thanks for any help,
k
