[BFW-5513] [FEATURE REQUEST] PCTG as new Material

[Keridos]

If it makes sense, enter what type of printer or upgrade the feature request applies to.
Printer type - MK4

Describe the expected functionality
Add a new material profile for PCTG:
Nozzle temperature: 260°C
Heatbed termperature: 100°C

Two examples for this type of filament

PCTG seems to have the same Temp specs as ASA. Shall it still be added ?

[bkerler]

I've added PR #3591 for this request. It would be good if you can confirm that you successfully printed with that material on the MK4.

[Keridos]

I printed successfully. Have not fully worked out the retraction settings yet as my sample was a bit too moist after shipping (suspect the packaging was faulty). But after drying it prints ok. A bit of stringing, but that's it.

Yes. It's much more straightforward from the user perspective. And combining them ("ASA/PCTG" in the menus, etc) would be a strange as they are completely different filament compositions. Leaving them as separate items, even if they have similar values under the hood, also allows the temps and profile characteristics to diverge over time if tuning and feedback suggest they print differently and do need different treatment.

[bkerler]

OK, then the PR should be fine for that. PCTG is a separate item.

[bkerler]

I added a new PR which allows usage of custom filament profiles, which is even more convenient :)

[silvvero]

I would also like to requst PCTG as new filament in the mk4.
PrusaSilcer support it in mk4 profiles so the machine itself should also support it.

Also the XL could use the ability to load PCTG. PCTG is available in PrusaSlicer, but not in the material load menu, leading to lots of warnings when sending a print as the materials do not match

Hey, I will try to push for adding support for custom material types. Unifying the related issues under the internal ticket BFW-5513

[CZDanol]

Hello, we've released a 6.2.0-alpha1 firmware with user material types support: https://github.com/prusa3d/Prusa-Firmware-Buddy/releases/tag/v6.2.0-alpha1

This means that while we decided to not put PCTG in our presets, you can set it up yourselves :)

[kvtorp]

I just did the following:
Defined PCTG on the XL
Loaded PCTG through the filament change menu
Sliced an object in PrusaSlicer, selecting the toolhead with PCTG filament
Sent the job for printing through PrusaConnect
Watched the job start on the printer

Everything worked perfectly, and there were no warnings, dialogs, or filament selectors bugging me about my filament choice in neither PrusaSlicer/Connect nor on the XL itself. Success!

@CZDanol Thank you for listening to us
