Meas 7i92M with DIY stepper driver board - PnPConfig setup

Hi,
I had the setup running before I reinstalled my laptop with the latest LinuxCNC version - stupid me didn't backup the "ini" file for LinuxCNC and I need help to recreate it.

I do have a 7i92M (IP 10.10.10.10) and use a self-made stepper driver board at the P2 connector, with the following connections:
Parallelport-Pin / IO-7i92M / Function:
1 / IO-0 / X-DIR
14 / IO-1 / X-Step
2 / IO-2 / Y-DIR
13 / IO-3 / Y-Step
3 / IO-4 / Z-Dir
16 / IO-5 / Z-Step     

I ran LinuxCNC-PnPConfig, but did not find any proper board/setup, that allows me to select this particular connection/config.

I remember previously it was straightforward to configure the individual pins for a 7i92M board - now I am struggling.
I am not sure which firmware is on the 7i92M board - but I assume it is the default, since I did not change it.

Any help is appreciated !
Thx

[Edit:] I found my previous discussion on the same topic in this forum from 3 years ago, but it does not help me much, since I cannot select and assign DIR/Step signals to 7i92M pins:   forum.linuxcnc.org/39-pncconf/43847-7i92...and-pncconf?start=10

 

The default 7I92 firmware is 7i92_7i76x2D.bit, and that matches your pinout

You should be able to to use pncconf with "7i92-Internal Data" and
"7i76x2 with one 7i76"  Then disable the sserial ports and encoder
(If you don't use one) and unused stepgens to regain control of
their GPIO pins
 

I did as you recommended, but in the PnPconfig under the "P2" configuration tab I can select for Pin0: "X-Achse StepGen"  assuming this is creates the stepper pulses - but how can I select the "DIR" function for Pin14 ???

Do I need to set "Anzahl der Schrittmotoren" (number of stepper motors)  to 0 as well ? 
Since I am using L297 drivers.

[Edit:]  OMG, no I understand the pinout display when selecting 3 stepper motors in the config.  This is really not easy to read, when selecting the stepper: the "0" covers 2 pins (IO0 and IO1) with ( I  assume since it is not explicitly given) the IO0-pin connected to X-Dir (when selecting X-axis) and IO1-pin connected to X-Step.

I took a while until I understood it.




 

I do have another question.
I found old parallel-port config files and want to extract the stepper scales and parameters for the 3 axis.

For which parameters do I have to search in this old config files ?
Is it in the *.ini or in the *.hal file ?

I find this:
[AXIS_0]
TYPE = LINEAR
HOME = 0.0
MAX_VELOCITY = 20.0
MAX_ACCELERATION = 30.0
STEPGEN_MAXACCEL = 37.5
SCALE = 228.571428571
FERROR = 1
MIN_FERROR = .25
MIN_LIMIT = -500.0
MAX_LIMIT = 500.0
HOME_OFFSET = 0.0

[AXIS_1]
TYPE = LINEAR
HOME = 0.0
MAX_VELOCITY = 20.0
MAX_ACCELERATION = 10.0
STEPGEN_MAXACCEL = 12.5
SCALE = 228.571428571
FERROR = 1
MIN_FERROR = .25
MIN_LIMIT = -500.0
MAX_LIMIT = 500.0
HOME_OFFSET = 0.0

[AXIS_2]
TYPE = LINEAR
HOME = 0.0
MAX_VELOCITY = 20.0
MAX_ACCELERATION = 10.0
STEPGEN_MAXACCEL = 12.5
SCALE = 355.555555556
FERROR = 1
MIN_FERROR = .25
MIN_LIMIT = -100.0
MAX_LIMIT = 100.0
HOME_OFFSET = 0.0
 

Now facing an error when starting this config in LinuxCNC - any idea ?

You can use parallel port joint ini values, though you may be able to increase
the velocity and possible acceleration values due to the increased steprate
and step smoothness from the hardware step generator.

I do agree that pncconf should show the physical pin numbers in addition
to the stepgen/pwmgen/ etc numbers to avoid confusion.
