Another custom BOB for 7192TH ?

After my happy success with the 7i96s, I decided to upgrade my MPCNC 3 axis machine.   

Ordered a 7i92th which is now waiting for me to pickup at the post office.  Thought I'd get a head start and built a couple cable assemblies.  Then started trying to configure linuxcnc.

I think I don't understand something.  Since I don't have a BOB expansion card and I was just building a 26pin hdr to my drivers (TMC2208's) I figured it should be relatively straight forward.  It doesn't appear to be; at least not to me.

This is what I've built:

P1
PIN    Function      Descr
IO17   GPIO Input    XMin
IO18   GPIO Input    X1Min
IO19   GPIO Input    YMin
IO20   GPIO Input    Y1Min
IO21   GPIO Input    ZMin
IO22   GPIO Output   Chassis Fan
IO23   GPIO Output   PS Fan



P2
PIN    Function      Descr
IO0    STEP0         X Step
IO1    DIR0          X Direction
IO2    EN0           X Enable
IO3    STEP1         X1 Step
IO4    DIR1          ~X1 Direction
IO5    EN1           X1 Enable
IO6    STEP2         Y Step
IO7    DIR2          Y Direction
IO8    EN2           Y Enable
IO9    STEP3         Y1 Step
IO10    DIR3         ~Y1 Direction
IO11    EN3          Y1 Enable
IO12    STEP4        Z Step
IO13    DIR4         Z Direction
IO14    EN4          Z Enable

and I tried selecting G540x2 'firmware' in pncconfig but I don't seem to have favourable options in the P2 tab for configuring my stepgens.

Sorry, thought I had a handle on this from my previous machine.

pin# is the pin number on the BD25/parallel port connector
I/O is the Mesa input/output number used in HAL

Is a firmware file for the pinout you listed (with 5 stepgens on P2)
and just GPIO on P1

pncconf seems to work with this using the discovery option

That "Thank You" button doesn't adequately express my thanks for your continuing help!

Thanks!

I was confused because pncconf listed:

P1: 017, 1, 5, 020, 9, 6, 024, 7, 8, 1, 033
P2: 000, 0, 0, 003, 4, 1, 007, 2, 3, 0, 016

as the Pin #'s and I didn't (don't?) understand how to translate that into physical pin numbers on the physical connector. Specifically, how is "000" different from "0" and "0" ?

I agree that pncconf could use better column labeling
The 3 digit numbers are GPIO numbers, and the single
digit numbers are module numbers (like stepgen 0,1,2,3
or pwmgen 1)

For your listed setup, pncconf config page setting should
look like this:

Main config page:

 

P1 page:

 

P2 page:

Oh! I had almost that! I missed the 'Amplifier Enable's and the "+ Home" parts of the limits.
