Unwanted filament changes on every print!

Hey all!

I'm experiencing requests for filament changes with every print. It seems to have started after disconnecting my MMU2, but not sure 100% on that timing.

It's not totally random, but seems to happen between layers even though I haven't added any color changes. I thought it could be related to the filament sensor, but given it doesn't happen randomly, it doesn't make sense for that. I downgraded to the previous prusaslicer thinking its a slicer bug, but it's still happening.

I've attached the gcode. Can anyone see anything in there that could be causing this issue?? 

Thanks!, it's driving me crazy!!

Ok, figured out the file posting issue. Gcode attached.

If anyone can figure out what is going on I would so appreciate it! It's made printing anything so painful.

RE:

Anyone from Prusa that could tell me what hardware/sensor problem that would cause the printer to pause between layers(not random), many multiple times during prints, ask for the filament to be removed, then asks for new filament to be installed? There apparently isn't anything in the gcode causing it.

It's literally made my printer unusable.

Thanks
