Problems With MMU 2.0

I have an MMU 2.0 that I recently installed on my mk3. When I turn on the printer, the mmu blinks green from right to left and then starts blinking red with 5 repeatedly before turning off. The mmu doesn't seem to be detected. I have flashed the latest 1.0.2 firmware through slic3r, and the blinking hasn't stopped.

I took a short video to demonstrate, but the LED colors aren't very obvious:

Re: Problems With MMU 2.0

I think your finda is triggered.

I have a Prusa,therefore I research.

The MMU is indicating some sort of error condition on initialization.

The most common cause is the FINDA senses filament in the MMU. If there's no filament in the MMU, it could be that your FINDA is the wrong height and isn't triggering correctly.

I'm running printer firmware 3.5.0, mmu firmware 1.02. I'll see if manually clearing the finda's pathway helps.

It prints - thanks for the help. A fragment of filament was messing with the FINDA
