Opening up the MMU3 to clear jams ?

Is there a way to open up the unit to see if there is a jam between the idler and the toothe gear ? I am having trouble with slot 5 preloading filament.

RE:

I do that by removing the two screws with springs from both sides of the MMU3 and the top part will basculate towards the rear, leaving access to the tooth gears.

As noted above - very easy to open. Just bear in mind the screw positions, and do not tighten down when closing - the screw heads should align just above the notch so that the springs have space to work.

Thanks! that worked.

LOL.

So, instead, read "open to the rear side"
