Hello, I am attempting to get the charge pump on a PMDX-131 working. I have had this board for years and am just getting around to trying to get this working.
I have a charge pump output setup on pin 17 as described in the PMDX-131 manual. Because I was unable to get this to work I also attempted to use a CNC4PC external charge pump board through a PMDX-131 output (Pin 16). This did not work either. I used Halscope to watch the output pin signal and I am getting a signal from EMC2 as expected (at least internally). I then hooked an oscilliscope to the output and did not get a matching signal. I have no signal at all. I connected the CNC4PC charge pump to a signal generator and it worked as advertised. I also have a spindle motor working through PMDX output 1 relay K1. Has anyone used the charge pump on the PMDX-131 with EMC2 successfully? Is there anything obvious that I am missing? My thought is that maybe the buffer on the PMDX can't handle the HZ. I am basing the signal off my servo thread and have manipulated that up and down to but see no output. I changed parallel port cables also.
