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.
