When I was using the mother board parport I have made a test box.

Attachment not found



This box is wired according to this schema: 
 

Attachment not found



The HAL follow this pinout:
Code:
# --- 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

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.

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 ?

I don't know what is is a "a DVM set in Diode mode".
Is ther any shcmatics for shorting to gnd or dvm set ?

Internet is your friend. I kwon what is dvm.
The test box works with parport. Wiring is OK.

DVM = digital volt meter

I will make a new test box

I can't use pull down for e-stop.
It isn't in logic with normal security wiring.

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