Ender 3 Filament sensor assembly (using orginal Z endstop)
thingiverse
Update 28.06.2020: Updates for slightly better fitting Z-Axis fixation. Added v2 to accomodate full Aluminium MK8 extruder. An Ender 3 (possible also PRO?) filament runout sensor using the original Z Axis Endstop (no longer required as BL-Touch is in place). Additional required: 2x M3*12 Screws for Z axis mount (original is too short) Extension for Cable (depends on your Board etc) recommended GUIDE for Firmware changes to enable filament sensor: https://youtu.be/gwHpXaj_6xE I used x endstop max connector (as it is default defined as filament sensor pin for skr v1.3 board) Holes need slight enhancement (3mm drill for z axis screw, 2.5 mm for board screws)
