Emergency Stop

@deckingman I built a folder and put a simple M112 in it. Test failed. I've got some checking to do. I suspect it may be a wiring issue. I'll have to work it out and get back with ya.

Suggest the first thing you do is change T2 to T0. That will work the same way that M112 does but without needing a trigger macro (that's why trigger 0 and trigger1 should not be used -T1 does a pause like M25). If that doesn't work, then you need to check your wiring etc. If it does work then you need to check the trigger2 file and /or its location.

@deckingman Yea its gotta be a wiring issue. I think I can sort it out. I'll get back with ya when I do.

@deckingman Ok I cant seem to figure out the wiring and I dont want to use the trial and error method my my new board. Do you know how to wire that particular endstop?

@SonnyD1 From a question in the the 'Question and Answer' section of the listing:

Question:
I assume the the green wire is the common? wireing needs to be in your description.
Answer:
Hi Green wire is common, Blue is NO, Yellow is NC.

So you can wire it NO or NC. We advise NC (Normally Closed), see https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_endstops#microswitch

Duet 3: connect the switch between the IN and GND pins of your chosen IO_x connector.

You said:

Do you mean you created a folder called 'trigger2.g'? It needs to be a text file, like any gcode file. And it needs to be in the sys folder.

@droftarts Thats how I have it wired. I have the green wire to the ground and the yellow wire to the signal. Also, I created a folder named trigger2.g with an M112 in it. I started a home all and hit the endstop and nothing happened.

@SonnyD1 said in Emergency Stop:

A folder, or a file? It should be a text file, not a folder.

@droftarts Yes it is a file. Currently named trigger0.g due to the "T" change you recommended. The file isn't even necessary with a T0.

SonnyD1

@droftarts I found the problem. It wouldn't trigger because I had a R1 instead of a R0 in my M581 command. I've changed it and it executes the M112 properly now. Any modifications I do on it from here on out would be easy now that I know. I would say this issues is solved. Thank you very much!

droftarts

@SonnyD1 R1 will only trigger while a file is being printed from the SD card. So it probably was working, you just weren't running a job! Also, yes, T0 and T1 ignore any trigger file, so any changes to trigger0.g won't do anything. You need to use T2 or higher to have it run what you want in a trigger#.g file.

@droftarts Thats what I may do later. For now I'm gonna leave it as is. Thanks again for your help!
