Manual filament-change.g syntax
-
Remove the last M291.
Are you using DWC or a PanelDue?

@Phaedrux said in Manual filament-change.g syntax:
I don't think M24 is needed because once the filament-change.g macro has completed it will resume.
That's not how my machine does it atleast (on 3.4 or 3.5). If i add a
M291 S2dialouge infilament-change.git goes on to a paused state after pressing "OK" andfilament-change.gends. And when i then hit "Resume" from the paused state it runs throughresume.g. This behaviour is the same on both DWC and PD.One should think that when adding
M24at the very end offilament-change.g(after aM291 S2) on the other hand, it should automagicaly runresume.gwhen the macro finishes up, so you don't have to go through the "extra step" of manually pushing "Resume". -
@Surgikill said in Manual filament-change.g syntax:
Any ideas? I'm not sure where the issue is. I can run M24 from a macro, but it seems as though I can't run it from 'filament-change.g'.
I've run some tests myself.
When M600 is used in a print, it looks like the pause start doesn't occur until after filament-change exits (or pause.g exits if filament-change.g didn't exist).
Therefore M24 within filament-change.g won't work as it's not yet in the paused state.
So I'm not sure how you can create a resume prompt.
You can't do it in the print file, because it won't be active until the print is resumed.
About all I can think of would be set a global in filament-change.g and do a check in daemon.g
something likeif global.doingChange = true && state.status="paused" M291 S4 K{"Yes","No",} R"Resume print?" if result = 0 M24 set global.doingChange = false -
@Surgikill said in Manual filament-change.g syntax:
What I want to happen is the print to pause, the filament to automatically retract, swap filament, press a button to load filament, and then resume the print after a prompt.
Further to my post above, you could do the unloading and loading in filament-change.g
In my case I have a universal_load and universal_unload macro.
Each of my filaments load.g and unload.g this as does filament-change.gSo your filament.g could work per your original thinking as far a using M98 to call pause.g to do the movements
Then call your unload and reload macros
It will still not be in the paused state till after all this, so you've either got to it the resume button or do something like I posted above.
I don't see having to hit resume as being a big deal. -
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.

@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 -

🤣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 -
