* For PRUSA_MMU2:
* T[n] Gcode to extrude at least 38.10 mm at feedrate 19.02 mm/s must follow immediately to load to extruder wheels.
* T? Gcode to extrude shouldn't have to follow. Load to extruder wheels is done automatically.
* Tx Same as T?, but nozzle doesn't have to be preheated. Tc requires a preheated nozzle to finish filament load.
* Tc Load to nozzle after filament was prepared by Tc and nozzle is already heated.
