I can't seem to get my Homing/Limits to work. I have tried almost everything.
The only way I can get them to work is if I disconnect my Breakout Board, but once I connect my breakout board the switch leds turn on as if they were triggered. I have tried running the Parallel port in EPP-1.9 and SPP, EPP-1.7 and SPP and Printer Modes but neither of them seem to help. Under Device Manager I told the Parallel port to accept all interrupts. This didn't help. Basically it seems like somewhere in the breakout board my input pins are grounding and theoretically being switched.
What am I doing wrong?
I'm using the following components:
Internal LPT1 Parallel port
Windows 7 32bit
