On the configuration page, make sure you select only the number of stepgens,
pwmgens, and encoders you will use (to free the pins for GPIO use)
pncconf lists both the GPIO numbers (3 digits) and module numbers ( 1 digit like stepgen 0,1,2,3 etc)
in the first column so its a bit confusing. Normally standard firmware will assign stepgens in a sensible
fashion so 0=X on BOB, 1 = Y, 2 = Z etc

Normally you would assign stepgens something like this:
For the I/O on P3 you would need to look at the pinout file
to get the DB25 <-> GPIO conversions to know which
GPIO matches which BOB pin

i dont think this is going to work for the dmm pinout. its missing pin 2 and pin 3

thank you. I don't understand what the purpose of IO connector 2 and IO connector 3 is? some "Num:" are in both. maybe I should remove the keyed molex connectors on the board and replace it with screw terminals. otherwise im stuck with that pin configuration. or make a new db25 cable

IO connector 3 is P3 on a 5I25 or 6I25 (the DB25 on the bracket end of the card),
which in all you need to configure unless you are using 2 BOBs
The pinout should be correct, why would you change any wiring?

it should look like my image
if you
1. Select 5i25 with internal firmware prob_rfx2
2. Set the number of encoders and PWM gens to 0
3. Select accept component changes
4 look at the IO connector 3 tab
