PETG Carbon filament requires higher temp for loading
I just purchased a roll of Atomic carbon-infused PETG filament. I also installed a hardened steel nozzle. Per spec, the temperature range of the carbon PETG is 240-265C. However, when loading filaments into the Prusa Mini+, the PETG option on the filament loading screen only shows a temperature of 230C, which is below the filament spec, especially considering the hardened steel nozzle (less heat conductive). For now I chose ASA for filament loading, which has a listed nozzle temperature of 260C for filament loading (and a too high bed temp of 100C, which slows down the loading process).
The problem is, whenever I print a model configured with PETG, the Mini+ will prompt me that I have a different filament type loaded, and if I want to abort/ignore/change the filament. I guess I can live with that inconvenience but my concern is that the incorrect filament choice might influence other printer behavior related to ASA vs. PETG filament.
Is there a way to customize the list of preconfigured filament types and temperatures in the filament loading screen? Or can that only be done via the firmware?
RE: PETG Carbon filament requires higher temp for loading
You can create your own profiles in Prusa slicer.
Choose the generic petg profile and adjust it to your wishes and specs.
Save this e.g. under the name Atomic petg.
RE: PETG Carbon filament requires higher temp for loading
I know about the filament profiles in Prusa slicer. I already cloned the Generic PETG to make an Atomic Carbon PETG profile. The "problem" is on the Prusa Mini+ itself. The profiles for "PREHEAT for LOAD" screen are too limited for this use case, and I'm wondering if that list can be customized. See picture...

You can use in the prusaslicer also the asa profile where in filament setting you can set your desired temperatures.

RE:
On the site of the filament you use I come across the following.
Print nozzle temp - 240 - 265C
Print nozzle size - 0.40mm or larger
Heated Bed temp - 60 - 78c
The difference with the petg mini load profile is 10 degrees.
I think you can just use the petg prehead profile of the printer to load.
When printing, the temperatures from the gcode file are used, so those of your created profile.

True. Can’t hurt trying it. If the filament gets stuck, I can manually crank up the temp to free it.

Hadn’t thought of that, good idea. I’ll try using the 230C PETG profile for loading first. If that doesn’t work well, I’ll got the PrusaSlicer fake ASA profile route.
