General Mach Discussion / Re: Another 2nd parallel port question
« on: October 13, 2011, 02:07:05 PM »
I swapped the cables around. Added the ribbon cable & header for the 3 parallel port.
Tried Mach on all 3 ports, no luck on #2 or# 3.
Called them all port #1,2 or 3 at one time. Went through all of the assigned addresses in device manager, too.
Pendant didn't work on port #1 ( motherboard provided port).
I have noticed that the LED on the pendant come on when you start the machine.
It stays on while Windows is booting up. A couple of seconds before the Main Windows screen ( with the icons) comes up, the pendant LED goes out.
I'm not sure but that sounds like something to do with the "charge pump" circuit.
There are (2) different CNC4PC brains. One is with charge pump, and the other W/O charge pump.< I've tried both
About an hour ago I sent an e-mail to Steve @ PMDX. This may be impossible, or he may have a 10 second fix.
I would be willing to wire this pendant pin-by-pin if takes that.
The only thing really needed is:
MPG
Axis selector
Axis increments; .001, .01, 01.
The E-stop had a relay that is wired outside the comm cable.
Stay tuned for further updates.
