Print preview wrong filament #31805 (CORE One) #26805 (MK4S…

What happened?

The printer can memorize the type of filament loaded in the print head. In case a GCode is loaded with a filament material setting different than the loaded material, the printer shows a message "A filament specified in the G-code is either not loaded or wrong type", or "This G-code was set up for another filament type".

Error name: Print preview wrong filament

Error code: #31805 (CORE One) #26805 (MK4S) #27805 (MK3.9S) #28805 (MK3.5S) #13805 (MK4) #21805 (MK3.9) #23805 (MK3.5) #17805 (XL) #12805 (MINI)

How to fix it?

Double-check both the loaded filament material and the GCode.

If the issue is with the loaded filament, unload it and load new filament using the printer LCD Menu >Filament.

In case the issue is with the GCode, reslice it and double-check it with our PrusaSlicer.

I'm having the same issue as Mihkel. I'm trying to print Prusament PETG-CF. There is no filament on the Core One, so I created a Custom one with the appropriate parameters. I'm also getting the "Material does not match" in Send to Connect, and the above warning message on the Core One screen.

Im about to print with extrud'r's PCTG filament on my Core One.
Unfortunately there is no such filament type available, so I defined a user filament on printer: @PCTG

Now what exactly I have to do in prusa slicer to get over the "Material does not match" warning in "send to printer" dialog?

I have created a custom PCTG filament profile for my Core One, but obviously Im missing something
