When I was using the mother board parport I have made a test box.
This box is wired according to this schema:
The HAL follow this pinout:
Using test box has no reponse in linuxcnc. Is there something wrong with theese datas ? I suspect 6i25 output voltage and 10k pullup/pulldown resistors of the test box.
This box is wired according to this schema:
The HAL follow this pinout:
# --- MACHINE-IS-ENABLED ---
setp hm2_5i25.0.gpio.007.is_output true
net machine-is-enabled => hm2_5i25.0.gpio.007.out
# external input signals
#--- ESTOP-EXT ---
net estop-ext <= hm2_5i25.0.gpio.003.in_not
# --- HOME-X ---
net home-x <= hm2_5i25.0.gpio.013.in
# --- HOME-Y ---
net home-y <= hm2_5i25.0.gpio.014.in
# --- HOME-Z ---
net home-z <= hm2_5i25.0.gpio.015.in

Mesa 6i25 inputs have their own pullups, so they need to be grounded to trigger.
Shorting them to gnd works, or use a DVM set in Diode mode, red probe on gnd, black probe on inputs.

Did I have to move W4 down to disbale 6i25 internal pullup resistors ?

Is ther any shcmatics for shorting to gnd or dvm set ?

I don't know what is is a "a DVM set in Diode mode".Mesa 6i25 inputs have their own pullups, so they need to be grounded to trigger.

The test box works with parport. Wiring is OK.

Internet is your friend. I kwon what is dvm.

DVM = digital volt meter

No need, you can invert inputs by adding "_not" to input pins in hal.
