bdwidth Optical filament width and motion sensor for 3D Printers (bd width)

bdwidth sensor is an optical width and motion sensor for 3D printer. Feature: Adjust the flow rate in real time Pause the printer while the filament jams and runout  Width accuracy: +/- 0.01mm  Connection: USB port or I2C port  No calibration required  Firmware update from the usb Package list: bdwidth sensor 1.3 meter i2c cable 1.5 meter usb type-c cable   Note： Transparent filament: It cannot measure the width of fully transparent filaments, but it can still measure movement.
