5i25 to PMDX-131 Configuration Issues

I have been working to configure a Mesa 5i25 connected to a PMDX-131. I have used MesaFlash to install the 5i25_dmmbob1x2.bit file to my 5i25 and I have configured the 5i25 to contain 4 stepgens. The dmesg appears to match my configuration, but I have been unable to get the steppers to move. I am able to turn the spindle on, I have connected a charge pump to pin 17, and have even been able to turn on my flood coolant. I have included the dmesg output below: If anyone has any ideas that may help me I would greatly appreciate it.

You will have a 500Hz charge-pump running through GPIO. The PMDX docs say that 100Hz is the minimum, so that seems OK.

Can you open a halmeter and check that the value of hm2_5i25.0.stepgen.00.position-cmd is actually changing value when you jog that axis?

Also please post your hal/ini files

That would save a lot of guessing

Please find attached all of the files in my config area.

As a quick guess I think you have your step times too short (500 ns)
for most step motor drives with optocoupler inputs, 2usec (2000 ns) is
probably a better starting point

OKay, headed out to change it now and test.

I am assuming you mean the steplen in the ini file.
