Orca tool changer support

[SoftFever]

Description

Add support of tool changer printers.
A new printer model has been added: Generic ToolChanger

Currently only support tool changer printers like TapChanger and StealthChanger.
Support for Prusa XL is still WIP. Prusa XL is supported now

⚠️WARNING⚠️ : please proceed with caution. It hasn't been tested on an real printer yet. Please double check with g-code before printing it.

🚀GOOD NEWS🚀: Multiple successful prints have been reported; it should be safe to try Discord Thread.
For bugs, please kindly help by logging issues with details and sample projects, then label them as ToolChanger. This will help me track them.

Test

Feedback is welcomed!
For Mac users, please ref to this instruction: https://github.com/SoftFever/OrcaSlicer#how-to-install

• Occasionally crashes when change printer settings
• Prusa XL profiles and custom gcode
• Ooze prevention bug
• Prusa XL z offset issue when prime tower is used
• Preheat nozzle(temporary solution)
• infinite(tall) skirt when both ooze prevention and skirt are enabled
• skirt/purge cone overlap
• Document about custom variables

Implement #5943 #2050 #5079

Would it be possible to get build artifacts for this, as it would allow more people to assist in testing, without needing to know how to build with Visual Studio?

[Hardy786]

I would love to test this out, but I am no Github genious, and have no idea how to get at it! Someone please point me in the right direction!

I was trying this for a Raise3D Pro 3 and this error appears everytime i try to slice.

Before i was doing it by enabling the manual filament changed with custom change filament gcode for extruder switching. I have removed everything in it and is still doing it.

I've attached the 3mf file for the project.

Ooze prevention should work properly now.

Looks like some setting is not right. Can you compare your configuration with the built in tool changer configuration?

@SoftFever
i have a running prusa xl 5 head config including the modified start stop and change gcodes

@hliebscher , can you share your start, stop and change gcodes for Prusa XL 5T?

[SoftFever]

Prusa XL 5T support has been added.
I've done manual g-code inspection, looks good.
Looking for experienced testers as I'm don't the machine.

Perfect!
I tried to port PrusaSlicer's XL 5T profile and keep the custom g-code as original as possible.
Can you review the profile I just added and let me know if it looks fine?

Hi !

So I did some test on Omni3D industrial machines (Factory NET, 500Lite and PRO) and everything is going well so far !
I wanted to give you a better feedback but honestly, there is just nothing to say lol, your build works perfectly for me.

To be honest, I did not go too deep. I just tried printing parts using 2 heads with dissolvable support, not crazy stuff. But I believe that's what most companies are interested in.

My coworkers were blown away to see those machines running on OrcaSlicer instead of Simplify. We are all used to slice with Orca at home but at work it's a different story and not for the best lol.
Anyway, thank you again for this build ! I can't wait to see it added on the new release of Orca !

Using the Windows portable version from this build: https://github.com/SoftFever/OrcaSlicer/actions/runs/10044929494

I had some trouble with a giant prime tower, even though the prime volume in the process settings and for the filaments were set to low values like 5mm³.

The problem turned out to be the flushing volumes, which had a multiplier of 1 and were auto-calculated for my white and red filament.
Since the button for flushing volumes is hidden when the SEMM checkbox in the printer settings is not checked, the slicer should probably also force the flushing volumes to be 0.

it shouldn't used the flush volume for tool changer.
What printer are you using? Can you share the project file?

Ah, my bad, I think the problem was caused by using and adjusting my existing printer profile to multiple extruders instead of creating a new one. When creating a new printer profile with the generic ToolChanger I could not reproduce it.

Anyway, my printer is a Voron 2.4 with StealthChanger, here is the project file:

I installed this version to test a Voron tool changer, which appeared to work ok, but when I changed back to Bambu X1C and start a print I get this slicer error...

the same problem, i built from the latest code.

The quoted issues have been fixed.
Can you provide a bit more info regards how to reproduce the issue?

Looks like you are trying to use flush_length variable in your stealth changer, which is not defined in this build.
You can try this PR instead: #6241

[FlisherOfatale]

I opened a buf related to a crash when using pre-multitool printer profile and converting them to multitool.

Hi great work, wish i have a mm printer :)

Machine Setup > Toolchanger thumbnail
• Will make a design for later with orca arena thumbnail

Filament Settings > Multimaterial > Toolchange parameters with multi extruder MM printers
• You can use param_toolchange.svg for this

Parameters > Filament for features

basically combined a spool with walls and surfaces icon

Parameters > Ooze prevention

btw you can tag me when an icon needed

[staal54a]

I've got to run somewhere so I can't grab screenshots/logs right now but I am seeing an issue where the "Extra length on restart" value is not utilized unless a prime tower is enabled. I have an IDEX with purge buckets and brushes set up so I want to be able to disable the prime tower and fine tune that extra restart amount to account for the minimal ooze I lost over the purge station.

If I haven't uploaded a screenshot/log within the next several hours or so, please poke me in case I forgot. Though I expect it should be easy to recreate if it really is an issue.

Merging it first to avoid more future conflicts

[webbbn]

Just wanted to say that I am currently adding multi-toolhead support to my Voron 2.4. It's my own design, based on the great work of TapChanger/StealthChanger, etc, and haven't gotten to the point of actually making any multi-color prints yet, but was able to test this over the weekend with what I have working, and it worked flawlessly.

I'm happy to see that it's been merged, and look forward to seeing it in an official release in the future.

I had some potential suggestions for improvement as I was working through configuration, but I'll hold those until I an confident I know what I'm doing. :-)

Thank you. Looks good!
Except the ooze icon feel a bit off.

It's not finalized yet ;)

Noticed strange movement to the prime tower at the tool change. After printing a layer, active tool touches the corner of prime tower and the proceed to dock. That action produces really nasty stringing. Also when using "no sparse layers" feature, theres smooth Z movement. That also produce strings. Would be nice to have some sharp movement to the side at full speed before moving to correct Z height.
