Hall sensor instead of IR filament sensor

[emard]

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.

Thank's for the reply! and logo embossing as in 2.6 alpha1 for text would be nice too!!! in stl format or what could be done! Le sam. 28 janv. 2023 à 14:56, Prusa-Support ***@***.***> a écrit :
