That makes me feel better. Where do we start?

Is there a way I can send you the files I have?

Just attach the HAL and INI to a message here.
You said you could jog one axis, if I understand correctly?

I can jog all three axis. Cannot home or run a program. It only works when the charge pump is off.

To start with the charge-pump:
I think you should have a PWM on the correct pin, but to check.
First open a terminal and clear the dmesg logNow start linuxcnc from the GUI.
Then clear the terminal (or open a new one) and typeCopy and paste all that output to text file, and attach that to a message here.

Unfortunately the output of dmesg and the first part of "show pin" has disappeared (probably off the top)
Perhaps do them one at a time.
However, we probably have enough info to activate the charge pump. It needs to be 10 kHz and 50% duty cycle, to add the following to your HAL file (probably at the bottom)
That should get the charge pump working.
Does that make sense? It is worth mentioning that emcmot.00.enable is a signal defined earlier in the HAL file, and a) Could be called anything, as long as it has the same name everywhere it is used (and I don't like that name as it looks too much like a "system" name, and it isn't. and b) In modern Linuxcnc the "newsig" command is not needed.

The pwmgen is used for the spindle analog output on the G540
The chargepump is fed by a stepgen (stepgen 4 on the first connector)
You can get a clean pin-out of your current config with:
mesaflash --device 7i92 --readhmid
(with the default 192.168.1.121 IP address)
if your 7I92M is set for IP address 10.10.10.10 you would need:
mesaflash --device 7i92 --addr 10.10.10.10 --readhmid

In that case, ignore most of what I just typed.

Charge pump still a no go. I redid the terminal commands singly and attached the results. I was sent a newer hal and ini from Mesa and have attached them as well.
