Hi, did you have issues where the filament breaks where it exits the sensor housing?

No, haven't encountered that issue. Is your filament quite brittle?

No, it turns out that it breaks because my end gcode moves up the Z axis by 2mm at end of print. But now I have another issue - it breaks off at the entrance of the extruder mid print. The angle where it enters seems a bit sharp.

It's an Ender 3, but the design in that area is the same as an Ender 2. I was thinking maybe an extension of the arm so that the sensor is placed midway so the entry into the extruder is less of a sharp angle (the current design of the sensor pulls the filament down instead of letting it curve naturally) - or I'll have to find another sensor placement that is right in front of the extruder.
