General Mach Discussion / Re: Newbie new parallel port question
« on: March 03, 2011, 06:04:44 AM »
Your step and direction pins should be different for each axis unless you are trying to do something special.
A typical configuration would be something like
X step pin 2
X dir pin 3
Y step pin 4
Y dir pin 5
etc.
The actual pin numbers would depend on your controller board or how you have wired individual controllers to your breakout board.
Within Mach you have to enable the outputs to see anything at the parallel port and you will only be able to measure a steady voltage on the Dir pins as you jog in different directions (the step pins pulse too fast for reliable voltmeter readings).
Does this help or confuse ?
