Hi tee2,
I experienced the same problem with the motors not changing direction. The ground wire was not in the terminal in the driver properly for the direction terminal. The wire was sitting below the terminal so when i tightened the screw it didn't grab it, but for some reason when i tugged on it, it stayed in, and i missed it the first time i checked my wiring.
It had me confused for a while, i still dont know why the motor even moved in the first place, but maybe you have a similar problem.
As for the y and z problems, it sounds like an issue with pin assignment in mach3 like bluerobotkid said. When I connected everything i had my step and direction pins reversed (ie step was dir and dir was step) and nothing moved at all.I'm still new at this, but this is what I have learned so far, hope it helps.
Cheers, Dave |
