Filament unload GCode

On my MK3S, I would like to unload filaments with much nicer tip than a long string I need to cut systematically with pliers.

I do not have the MMU2S yet to perform this.

Do anyone already created a piece of GCode to mimic the filament extraction from the extruder with the cooling steps and speed variations like performed with a MMU2S?

Thanks in advance for your replies.

I don't have a Prusa so I can't say that your printer will honor the function but M660 is filament change. I appearently requires ADVANCED_PAUSE_FEATURE to be enabled, again don't know if Prusa has that turned on. Anyway I'm sure you can simulate it with more basic GCode commands.

Oh better Idea, make a dummy and slice it with a colour change then look in resulting GCode.
