M581 in RRF3 not triggering trigger2.g
-
@deckingman
Hi it is wired to io2.in which are the general io pins on duet3.If I configure io.2 as an end stop, it works so therefore proves the wiring is ok.
-
@bearer
I have put trigger2.g in the /sys folder as per documentation.
I have tried with and without spaces between P and T parameters, neither of them work. -
@chas2706 have you tried adding the '^' to the P parameter. You have it configured for a High->Low transition but if it is not already set High by the pullup the Board wont see it.

@tekkydave
Ok thanks. I will try that later. I'm printing at the minute.
Cheers. -
@chas2706 I use this M581 P"!0.io3.in" T2 C0 which is pretty much the same as you. I also have a file called trigger2.g in the .sys folder. The reason I asked which pins you use are so that I could compare your configuration with my known working one. Mine is connected between io3in and gnd so I ask again, "which pins are you using"??
-
@deckingman
It is wired the same as your only on io2in. Connection is between io2in and gnd. -
Like I said above, if I change M581 code in config.g to M574 P"!io2.in" , the switch acts as an end stop and works as such and so proves the wiring is correct.

its not what you wrote so there we ask to confirm..

Snippet from M581 Gcode documentation...…..
Any trigger number # greater then 1 causes the macro file sys/trigger#.g to be executed.
…….That is what I have done.
In my sys folder where config.g etc resides I have placed the trigger2.g file as per documentation.

@bearer
Sorry, there was a typo error in the first post. It should have said:The file trigger2.g in the sys/ folder has the following code...…..
-
If I put M581 ^P"!io2.in"T2 C0 in config.g as you suggested I get the following error:
Error: M581: Missing port name string when config.g reloads.
-
^goes inside the""is it safe to try and execute the trigger macro to see if there are any issues with the code?
M98 P"/sys/trigger2.g"should to the trick to see if its okay... or just post the config.g and trigger2.g contents so people can see whats going on.

@bearer
Running M98 P"trigger2.g"in the console works.
adding ^ inside "" does not.Here is my config.g:

Ok here's what ive found:
In the M581 command I re-introduced the missing space between the "io2.in" and T2.
I operated the microswitch connected to io2.in and nothing happened.
I started a print and operated the microswitch and the trigger2.g executed.
It seems that the "C0" parameter to set the code to execute at anytime does not work and only operates when printing.
Or am I missing something? -
In the Gcode description for M581 it says:
M581 - RepRapFirmware 3
Parameters
P Specify one or more pin names
Tnn Logical trigger number to associate the endstop input(s) with, from zero up to a firmware-specific maximum
C Condition: whether to trigger at any time (C0, default) or only when printing a file from SD card (C1)The Condition for C indicates that when set to C0 will trigger at any time. This is not entirely true. It will trigger AFTER all current moves have finished.
So it is useless for my purpose. -
@chas2706 said in M581 in RRF3 not triggering trigger2.g:
It will trigger AFTER all current moves have finished.
i belive that could be a bug as it did behave like described in the documentation a while ago.
which versio are you using?
M115will show it. -
@bearer
Oh right maybe it is a bug.I'm on version 3.0RC2.
-
Hmmm... I'd expect the trigger to instantly start executing the trigger2.g... however, I'd expect the commands inside that file to enter the planner Q like anything else.
Phrased another way: If there is a long running single G-Code command executing at the moment of trigger, the first command (other than M112 estop, which is handled in a special way) inside the file cannot start until the current command finishes. It also might be true that a chain of short moves that have been treated by the planner as a connected chain, that (dynamic) group of commands might have to finish.
I have no hands on to current or past behaviors. The above is just what I'd expect from the way the planner works.
-
@Danal Last time I tested it on my gen 3 main board (about 2 months ago) it worked as expected/intended (i.e. practically instantly even when printing). The only thing I'm aware of is that M581 is not currently supported for gen 3 expansion boards but both the OP and I are using it with the main board.
@chas2706 Try removing the H2 parameter from the G1 move in the macro. As long as the printer has been homes, it isn't necessary and maybe H2 moves within a print get ignored (because the H2 parameter is usually only used when homing).
If that doesn't work, can you add M118 S"Trigger 2" to the start of your macro. Then check if you see that message when you trigger the macro during a print. I'm just wondering if the macro itself is being called but something is preventing the contents of the macro from running. Adding a message at the start of the macro will prove if it is being called or not.

That would certainly be preferred! I'll keep reading as you guys experiment with this. Very interested.
