H2D Filament lodged INSIDE the Hall effect sensor chamber

Hey all,
After disassembly of the extruder on the H2D multiple times and not finding a stuck bit of Filament I’ve managed to find an edge case where a sliver of filament can get stuck in the Hall effect sensor chamber of the H2D Filament Sensor.

Since documentation didn’t have any info on this, I’ve attached photos of where it occurs in case anyone runs into this down the line.

I’ve also logged it with support.


This image with the dark grey bit of filament shows the culprit.

It looks like the filament somehow peeled away into the chamber.

Note that you can slide filament inside of the sensor and completely miss it. The way I figured it out is that looking THROUGH the PTFE channels you should see the spring arm obstructing the channel somewhat. If the channel is completely open you have something lodged beneath the Hall effect circuit boards on the sides of the Filament Sensor.
