Add "Manual filament change" option and logic #2379

Ocraftyone · 2023-10-10T09:30:52Z

This option does a few things that make a SEMM setup where you are manually swapping the filament on pauses a bit easier

disables calling the "on filament change" gcode during setup. This may be useful on a machine that can change the filament itself, but for manually changing the filament, it is an unnecessary pause. It should be assumed the first inserted filament is the first one to be used.
tool change command is changed to a gcode tag. This prevents errors on machines that do not understand the command possibly resulting in a failed print (or at least error messages).

fixes #1377 and fixes #2230 and fixes #2356

The only thing that may cause a bit of trouble on this is changing the configs to update for this. The config value is defaulted to true (as i figure a majority of printers don't have an AMS/multi extruder system) which may cause issues for edge cases. There are a few paths that I see, but I don't know which is best

disable it by default
change configs of affected machines to have it disable by default
find a place to integrate logic that if there are multiple extruders/AMS detected, disable and set false
LMK what you think is best and if you have any tips for the implementation

Awesome.
Thanks for taking care of these issues 👍

I suggest we disable it by default.
The reason is it's default behavior(disabled) in other slicers.

@SoftFever just made that change

@Ocraftyone Thank you for your patience.
I made some small changes in 66707c4
Please review.
If all good, we are good to merge 👍

I have a bit of concern about when the tag is inserted in to the code. I'll look into it a bit more later tonight.

@SoftFever I just made a review with my concerns

Wouldn't it be better to keep the tag variable name in camel case to match the format of the other tags? For example, Manual_Tool_Change. (To be clear, I am perfectly fine with how the tag presents in gcode)

You are right.
It is better to make it consistent 👍

Is there a reason for dropping the "T" here? The T is currently used when processing the tag as it removes the tag then passes the rest to the original process_T method (See GCodeProcessor::process_tags Line 2122). This could be modified, but I think the T also makes it a bit clearer what the number means.

I didn't mean to delete the T, must be deleted by accident.

I found another bug see my comment of my new commit.
I didn't a quick test, it should work well now.
Let me know if the test go well on your side.

Do you get the chance to review the changes?

Ocraftyone · 2023-10-21T11:23:37Z

Sorry. Only concern I have is that I originally tried using the SEMM optgroup, but I believe the on change function has been changed and doesn't update the plate correctly. Is that working for you? (Like mark the option and it prompts you to reslice)

Changing to other optGroup won't affect it.
It didin't invalidate the slice status properly because the PR didn't handle this new option in invalidate_state_by_config_options function
I will fix it with some other options in a separate commit.

I did try it, and the printer indeed stopped at the correct layer but there was no way of 'resuming' the printing after my manual filament change. Selecting the 'Resume' command didn't work as klipper/mainsail said it wasn't in a 'pauzed' state. What did I miss?

You need to configure your "Change filament G-code" on the machine G-code tab and the corresponding macro on your klipper configuration. For example, I use the M600 G-code command and I have a M600 macro where I first save the position, then move the nozzle forward and unload the filament. Then I load the new filament and click resume and that's it.

thanks, that'll do the job. I've found a nice example M600 macro on reddit and I adjusted the pause position to the place of my purge bucket

Please share the macro you are using... even with 1.8.1 this is still pausing for me after purge line completes. thx!

thank you, found it! I have not seen this documented anywhere.

Do you have a macro that does a purge or extrude N mm (say 20mm) before it resumes?
... would be a REALLY nice addition to printer settings, right under the change option ;-)

It is not possible to do this in Orca, you will need to modify your printer's macro to do this after the filament has been changed and before printing resumes.

Ask in a forum or group for your printer

By the way, ORCA has a setting finder. It is a magnifying glass icon.

Thank you for the help!

Yes but not a single search across all settings. Would love to see a single global search. Settings are divided between Printer/Machine, Filament, and 'Project' (left part of the menu that is not actually labelled). Not always obvious where to go hunting.

dobainier · 2023-12-23T15:43:33Z

Hello,
Thank you very much for this feature.
But I think I missed something when I tried it :
I enabled "manual filament change" in printer's parameter and added a "change filament", the filament parameter are the same but it's a different filament color in preview tab.

But when printing it didn't pause to change the filament...
Do i need to add an M600 command in the Gcode ?
