topic_solved Duet 2 Wifi trigger with Hardware Button not working
eisi last edited by eisi
i am new to this forum, i have built an BLV MGN Cube with an Duet2Wifi. I have a struggle getting my hardware buttons to work, (2 "Normaly Open" buttons) with them i want to set 2 triggers, one "babystep up", "the other babystep down".
One button is wired to the E0 endstop connector, and the other to the E1 endstop connector (GND to STOP)
when i press the buttons i can see the LED's for the endstop light up, but no babystepping
here are my changes to the config.g: (i am on RRF 3.1.1)
M574 E0 S0 P"e0stop"
M574 E1 S0 P"e1stop"
M581 P"e0stop" T2 S0 R0
M581 P"e1stop" T3 S0 R0
and the both "trigger#.g" files in the sys folder:
M290 R1 S0.05 ; babystep up 0.05mm
M290 R1 S-0.05 ; babystep down 0.05mm
when i test the triggers with the M582 command, they are making what they should, but with my hardware buttons there is no reaction.
does anybody have a idea how i can fix it?

@eisi your M574 E parameter is for RRF2, but you're using RRF3 where E doesn't exist. Please check https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3
for RRF3 syntax. You will have to replace S0 by S1 and ! also.

i found myself a solution:
my error was that i not assigned a M950 command.
now my hardware buttons are working.
the M574 is absolete on RRF 3.11 if using a M581 command.
