A

• stop (abort) loading filament (idler sensor detection triggered for T-codes and C0 code)

• not confirmed by ok

Tx 

• if filament loaded unloads current filament
• selects and loads filament x
• once done confirmed by "ok\n"
  
  

Lx

• loads filament x into the unit
• if successful or canceled by user on the unit returns "ok\n"

Ux

• unloads filament if loaded
• once done confirmed by "ok\n"

Gcode implemetation : M702 C sends U0 to the unit, waits for "ok\n" from the unit.

Sx

• if x = 0 returns "ok\n"
• if x = 1 returns MMU2 firmware version
• if x = 2 returns MMU2 build number
• if x = 3 return power failures count

Mx

• if x = 0 sets mmu to normal mode
• if x = 1 sets mmu to stealth mode

Fxy

• sets filement type y to the extruder x ( not implemented )
  

Xx

• MMU reset ( not implemented )
• currently just X0

Px

• read FINDA
• currently just P0

Cx

• continue loading after error
• currently just C0

Ex

• eject filament x (move selector sideways and push filament to the front)

Rx

• recover after eject
• currently just R0
  
  

Wx

• wait and signal load error (typically used in MMU load fail)
• currently just W0
