Filament won't load IR Sensor calibration good
My MMU2 won't load the filament to the nozzle. As soon as it gets far enough into the extruder to pop the idler gate open - the extruder stepper reverses and spits the filament out. In other words, as soon as the IR sensor says the filament is loaded, the extruder reverses and spits our the filament. Why?

Check your gear alignment. Sounds to me like the filament is missing the PTFE tube.
I am not familiar with the filament path for the MMU2, but it still has to make it's way into the PTFE.

Alignment is spot on, no problems there, as to the [tfe tube - it doesnt ge that far before reversing
