Hall sensor instead of IR filament sensor #192

Open emard opened 1 year ago

emard commented 1 year ago

Instead of IR sensor with a PCB, steel ball and mechanic arm with 2 magnets in repulsion, filament sensor can be simplified to 1 or 2 cylindrical magnets 5x5 mm in attraction and Hall sensor in 3-pin plastic transistor package 4x3x1.6 mm.

no PCB, no ball, no mechanic arm no physical rig for magnets to stay together - easy assembly. Less moving parts = less force required = less friction to the filament.

Hall sensor Honeywell SS495A or similar for 5V is directly wired to printer's motherboard, no additional electronic parts.

This is my project I'm currently upgrading MK2S->MK2.5S you can copy, remix or take sensor design as inspiration. https://github.com/emard/filament-sensor
