Manual filament-change.g syntax
-
A little further digging confirms that until filament-change.g has completed the printer status is pausing.
I put this in filament.change.g
echo "Printer state is: ", state.status
And got back
Printer state is: pausing
And looking at the 3.5b3 source for M24 it specifically ignores any M24 call in that statecase 24: // Print/resume-printing the selected file if (pauseState == PauseState::pausing || pauseState == PauseState::resuming) { // ignore the resume request } -
I'm working out a solution to do what you're asking for now @Surgikill, based on what @OwenD mentioned above with a global and
daemon.g.I've got a proof of concept
filament-change.g&daemon.gwriten, but i haven't got time to test it before tomorrow. -
@OwenD My issue with resuming the print with the resume button is it is very easy to fat finger the cancel button. There also is no sanity check after hitting the cancel button, hence why I want the resume to happen in its own prompt, therefore no fat fingering can happen. Even having a system prompt occur to resume print after filament-change.g completes would be preferable to having to use the resume print function.
@Phaedrux I'm using it on dwc, but I also have a machine with a paneldue that I can try it on, but it appears that doesn't matter from what @OwenD has figured out.
@Exerqtor Could this just be a bug and M600 with filament-change.g is not working as intended? From the wording of the documentation, it seems like the order of operations is 'pause printer'>'execute filament-change.g (or pause.g)'. It seems as though the filament-change.g is locked inside the pause operation, although the source for 3.5b3 seems to indicate that it is intended to lock the printer in a pausing state during a filament change.
-
@Surgikill calling pause.g at the start of filament-change.g is OK if it does what you need at that point.
Perhaps we need to allow a M24 within filament-change.g to resume the print as soon as filament-change.g has completed.

That would surely make life a bit easier

@dc42 Putting the printer in a pause state before filament-change.g is run would also work, although that seems like it may be more work. Either one would be great though.

@Exerqtor
Your M24 is not indented in the example -
@OwenD said in Manual filament-change.g syntax:
@Exerqtor

🤣Typo when I pasted it into the forum😳I'm using it right now btw, and the pause-resume handeling is working just like intended
✌️(the rest if the macro needs a little polishing though) -
@Exerqtor Thanks for that. I'm going to try modify those files a bit to set them up the way I want. From the documentation it looks like daemon.g will work on 3.4.5.
-
No problem! Yeah sorry I just copied that part from my
daemon.gwhich containsif fileexistsfarther down (I'll edit the post straight away).If you're running pre 3.5 the only thing you would HAVE to change in
filament-change.gis to remove the following lines:- 41-42
- 52
- 54-55
- 63-64
EDIT:
I forgot to mention you would of course also swap out the
M291(line 66-72) with something pre RRF3.5 friendly, like this for instance:M291 S2 R"Manual Filament Change" P"Change & prime filament, then press OK." G1 E{var.purge} F200 ; Purge filament -
