T?-Tx - MMU2 Special Commands

2.0.0 control MMU2 special filament loading commands

Description

For the MMU2 (and other Multi Material Unit clones) the T0-T7 commands select a new filament. After this command you must extrude at least 38.1 mm of filament at feedrate 19.02 mm/s to reach the extruder. (The distance to the extruder may differ for your particular machine.)

Special Commands

  • T? : (Requires MMU2_MENUS) Wait for target temperature, then load the filament all the way to the nozzle. G-code to extrude more is not needed.
  • Tx : (Requires MMU2_MENUS) Load the filament up to the direct-drive extruder gears. No heating is required.
  • Tc : Wait for target temperature, then load the filament from the extruder gears up to the nozzle. G-code to extrude more is not needed.
