While writing gcode for T3694 I am unable to trigger the Z-Min/Probe
Previous test stand gcode utilizes M226 (wait for pin state) to force the tester to trigger the probe before the test will proceed.
This is necessary to verify the circuit is functioning properly.
I am able to walk the unit through G29 by triggering the probe and holding the switch while running M119 reads triggered, so I know everything is set up properly on the hardware end of things.
M226 P31 S1
prevents the unit from proceeding through the remaining gcode, however I am unable to trigger to allow the gcode to proceed.
M226 P32 S1
gives the same result
M226 P31(or32) S0
the unit ignores this line and proceeds.
M42 S1 I am unable to read voltage between nozzle and bed ground
M42 S0 I am able to read 1.8-2v between nozzle and bed ground
Running either prior to the M226 does not affect results.
If you know of another way to do this I am open to ideas. The goal is to have a test that starts from a gcode with stock FW and have the test unable to proceed if:
a) the test is running unsupervised
b) a failure occurs
