endstop trigger and bangbang questions

[Phaedrux]

It's hard to tell from the photo of the wiring bundle but have you followed the Duex wiring guide on connecting the grounds with a short piece of wire as shown here? https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring

Can you send echo sensors.gpIn[1].value and report the results?

[deltajegga]

yes its wired the same.
i get this back

Error: meta command: array index out of bounds

@deltajegga said in endstop trigger and bangbang questions:

;M950 J1 C"!^duex.e2stop"
;M581 P1 T0 C0

You've uncommented these lines right?

@deltajegga said in endstop trigger and bangbang questions:

Error: meta command: array index out of bounds

means gpIn[1] doesn't exist, so either the M950 J1 command wasn't run or it didn't work

What do you get if you send just M950 J1 in the console?

[deltajegga]

hahaha, silly me. i guess it would help if i uncommented them.
ok i get a value of 0 back.

and if i send the m950 j1 i get back
Pin !duex.e2stop, active: false

M950 J1 C"!^duex.e2stop"
M581 P1 T0 C0 S1

And with this? Does it work as expected?

[deltajegga]

no, it still resetes if i home

[Phaedrux]

I wonder if having the wiring bundled like that is causing the e stop switch pick up the signal from the endstop.

Usually when I'm making my looms I always twist the wires to try and prevent cross talk. Can you physically separate the wiring for the e stop from the bundle and test again?

[deltajegga]

ok, interesting. so that solved the triggering when it shouldent problem. (i allways thought that only pwm and data lines cared about twisting.)

but it still wont trigger when i press the button. just a reminder im using a normally open switch.

Try changing it to normally closed. This should be configurable with the S0 S1 switch, but it's worth a shot.

I twist or braid everything when using cramped conduits. Just as a matter of habit.

[deltajegga]

yeah still nothing.

[Phaedrux]

And you're sure the switch really works?
Do you have a regular endstop microswitch you can connect in its place to test?

[deltajegga]

yeah i tested it with a multimeter at the plug on the duex.

@deltajegga In RRF 3.1.1, the 'C' parameter has changed to 'R'. See https://duet3d.dozuki.com/Wiki/Gcode#Section_M581_RepRapFirmware_3_01RC2_and_later

Try changing command to M581 P1 T0 R0 S1

damn, got my hopes up. i tried that with !, ^, and !^ on the pin name but still nothing. here is a refresh of the config.
