When the internal sensor lever is in use, no armature bearing prevents filament exiting the opening formerly occupied by the armature bearing. Installing a filament path insert closes that hole.

This part actually goes into the motor plate, but we cover it here as part of the internal lever MMU2S installation.

Position the filament path insert into motor plate. It is easier to handle with tweezers.

Secure filament path insert with M2 x 6 mm screw.

Sight down filament path and adjust insert position so filament path is enclosed but not constricted.

Filament path insert MUST be removed for single filament armature sensing option.
