General Mach Discussion / Stepper Motor Rings/No Movement.

« on: August 29, 2010, 08:25:09 PM »

I have a homemade cnc router with 3 axis. Breakout board connected to parallel port via 25 pin cables (two cables connected as adaptors). I set ports and pins correctly(I really believe this). When I hit any jog button (+x, -x, +z, etc.) no motor actually turns but I hear it turn. When I hit the +y nothing happens. When I hit the -y in Mach3 it rings constantly until I hit the +y and it shuts off. Sound familiar to anyone?
