This is a modification of Surfalex2000's Exit Filament files.
I trimmed out a lot of the fluff that was unneeded, added in my centering to ensure the print head is in the center, fixed the comments on each line, and changed the speed to match that of prusa's MMU filament swap. I also increased the retract 2mm from 65 to 67. For me, 65 stopped the tip of the filament directly in the bondtech gears, so I added the little extra.
I'm only included the two main printing filaments, PLA (215) and PETG (230) at the prusa default preheat temps. You can open the Gcode and modify the two hotend temp lines to match your filament as desired.
EDIT: I've added files for the Mini as well.
EDIT2: Modified them to add an additional cooldown. After the filament is ejected, the nozzle temp is set to 100C and the fan is turned on to help cool the nozzle faster to reduce any cooking of leftover filament in the nozzle. Once 100C is reached, everything is turned off.
What happens in these files:
1: Max feedrates, jerk, motor current, etc. set for safety (values taken from a file sliced in Prusaslicer 2.4.0 with default MK3S+ and Mini settings)
2: Extruder temp is set.
3: Printer homes, then centers, and waits for the hotend to reach temperature.
4: Filament is extruded, then retracted fully.
5: Nozzle temp is set to 100C and the fan is turned on 100%
5: Hotend/Heatbed/Fan/Motors are turned off, and flow/LA/current reset (Again, footer from a sliced file for safety)
As with all my gcode only files, everything is commented in the files, feel free to open them in a text editor to review.
