Hello all,
I have been using mach 3 for 2 years now on the same machine and set up with no problems. Suddenly I turned on my machine as usual to do some work and no dice the motors didn't move. The dro shows movement, but that's it. The limit switches did work. and the estop was functional. I tried a new driver, new motor, new computer, different version of mach3, different parallel port cable. The only thing that does work is increaseing the steps in motor tuning but the machine only crawls without accuracy. also the limit switches did work but with new driver don't respond and arn't reconized. the estop still works. I'm confused and have exhausted my options, any help would be appreciated..
