Hey 12, thanks for the reply.
I don't see the signals in the clearpath software, I see nothing there. But the drives work fine using the MSP software.
What I see is that the LEDs on the PMDX board are blinking as I would expect, DIR coming on and off with each press of the test button and STEP barely illuminating and getting more intense as the pulse train ramps up.
I looked at these signals with a scope looking for pulse duration and better see what was actually happening and thats when I saw the low volt signal. I understand that excess current would drag the signal down, but as you said the board should be able to provide what the Clearpath requires and other folks have this working.
I don't have a current probe for this scope so I can only read the DIR signal's current with a meter, I can do that tomorrow. FWIW I did reverse them with the config dip switches and the results were the same. Its also of note that the PC +5v pin is fine the whole time.
The Clearpath motor is set for Step and Direction -doesn't appear to have any other options available, they are greyed out in the software. I never saw any way to tell it what signal types to look for but I was hoping there was such an option in there somewhere.
Set for 800 Pulses per rev, as delivered.
Config switches are set per switch table, the pulse train occurs when it should and direction toggles properly as well, its just that the voltage is too low.
I'm not following what you mean by using the PC+5V to the Clearpath + etc.
