I have a plug-in pendant:
CNC4PC
This is the board that connects it to the2nd parallel port:
CNC4PC
The problem is, it will only jog in one direction.
When it is turned clockwise, the machine will go in the -neg direction.
When turned CCW, nothing??
I have traced down the wire and they appear to be on the correct pins.
How do you test an MPG?
If it pulses clockwise, shouldn't CCW be ok also?
Does it require A & B both to pulse?
Thanks for the help,
