Filament width sensor (hall sensors)
thingiverse
The idea is based on https://www.thingiverse.com/thing:4138933 You need for V1 sensor: 2pcs small 623ZZ bearings (OD:10mm, ID: 3mm, W:4mm) 2pcs small M3 washers (washer goes under bearing) 6pcs M3x8 screws spring from an automatic pen 4Pin right angle male terminal 2pcs ss49e hall sensors one 5x2mm magnet wires some tube connectors The sensors are placed the same way as in the original design. For configuration and calibration info please check the original thing. I have connected it to BTT SKR V1.4 TFT socket (sensor1 -> RX0, sensor2 -> TX0, GND -> GND). Adc ports: P0.3, P0.2 Power for the sensors is taken from WiFi socket (3.3V) **Made a smaller version V3 of this sensor!** Instead of bearings, it's using 2pcs 5x8mm rollers (roller bearing rolling element) STL files for that design will have suffix V3 Everything else remains the same. Enjoy!
