Filament sensor and cleaner

prusaprinters

Inline filament sensor and cleaner WIP (work in progress) To avoid cluttering in my enclosure i feed filament from another closet section by ptfe tubes. Previously i mounted the filament sensor and a separate cleaner near the filament roll but i found it inconvenient to miss the meter of filament when it the sensor triggered and the hassle of feeding so much filament in one tube. This new setup i can have several tubes ready to go and just swap near the extruder. This version is meant to feed a tube in one end and out the other to the extruder, for bowden setups i would recommend having this before the extruder in case the filament is soft enough to curl inside the cleaner. I think this would work fine without tubes as well, but i have not tested that yet. This version has the large bore PC4-m10 connector, but i may make a PC4-m6 at a later point as this could be more convenient. To thread the connector i simply heated it carefully and threaded it while hot. Dont burn the plastic component of the push connector. This is my working prototype for now, but with some more experience using it i may create revised versions. If you have suggestions for improvements i post a comment. Category: 3D Printer Accessories
