Certainly a printed manual is preferable.
The PathPilot install provides you with all their machines as a choice, so various lathe and mill models.
I had to make a custom cable to align what PP wanted with what my BOB wanted, not all the signals lined up in the standard 1-1 cable.
The reason for suggesting P2 is that the PP hal files all reference P2, If/when you update PP it overwrites your modified config, so the less editting the better
Re: motor/vfd I think you are correct. This thread seems to give more speicifics one what you need to change to use PWM to Voltage with PP. I can't help with that, my spindle is either on or off
As you can see from the below, the cable pins differ between Tormach machines (the more modern ones use a custom board so do not apply at all). A quick glance at your C11 board lead me to say you need a custom cable to get the pins aligned with what Tormach expects. You would then use the Tormach supplied .bit files, not the one for C11. On the other hand you could edit the PAthPilot .hal file and 'fix' the pinouts that way. For me that was too daunting a task to start with. I might get ambitious later, first want to get my machine running.

Hi PCW,
Thanks for pointing that out, I think I did notice that. The c11g I found in another thread on here, completely different form factor than my c11, so I would definitely reference/use the c11x2d version. I'll just need to research how to make the spindle work

Hi Gerri,
To clarify what you're saying on a custom cable and referencing the tables below for the 440mill:
the column that says "db25" and column labeled "mesa" would mean that tormach uses pin 14 on their BoB for spindle speed, and mesa expects that to be on pin 1? So the bit file is what makes that decision.
To continue that example for a custom cable (assuming for example c11 used pin 14 for spindle speed, and mesa pin required pin 1) I would simply wire pin 14 from c11 to pin 1 on the mesa side. It might be opposite what I listed.
I feel it would almost be easier to do a 'find and replace in the hal file to make the changes virtually. I don't know how much surgery that would be though.
Already learning alot - thanks for the help gents
