At first glance:

Change  step times from 500 to 4000

The charge pump needs to be done with stepgen 4
(the software charge pump will not work)

Recent versions of pncconf know how to setup a stepgen as a charge pump

I got the charge pump working. I'm still having trouble with the axes.  The led on each of the direction pins on the C11G board lights momentarily when I let off of the jog button. It is brighter in negative than positive for some reason. Pins 1, 14, 16 and 17 are all on constant with the charge pump. (Which I think is fine. nothing connected to those terminals)
I used pncconf wizard to generate the files. The only thing I did to them was comment out lines 22 and 23 to make it not crash. I tried to match up all of the parameters from the previous ini and hal file in the wizard.

Thanks again!

The direction signals are not really significant as they
may toggle once at the end of motion. I would try with
actual connected hardware.

The drives are there and should be working.

I had this whole mill making chips well for a few years with a parallel port and 2.7 i think. A power surge took out the VFD for the spindle. There was some glitch with linux that the screensaver wouldn't wake up so you'd have to reboot. I had that one bypassed, but it resurfaced and I couldn't remember how to fix it. I made a bad vfd buy on ebay and later a couple of stepper drives went bad at some point. Then it sat for a while. I'm trying to get it running again now.

It has some new to me used gecko 201's on all 3 axes. Its got an offbrand new vfd that works in manual mode at least on the spindle. and a new (used) PC with 2.9 on it.

I checked for movement on all three connected axes. Seems to have different holding torque on different axes but no movement whatsoever.

Did you set the step times to 5000?

Thank you! That did the trick. I did that when I was trying to mash two files together, but when I realized that I could use the wizard i forgot about it plus the wizard lets you select the drive which gives you 500 for that value which maybe keeps you from running away or burning something up but doesn't do much for making the motors turn. I dug the other specs out of my old files for the drive and put them in the wizard and the steppers sound happy again. Now I just have to get the spindle drive to respond and I'll be back where I started :O) Thanks again for your quick replies and patience with me.
