Impulse filament sensor

Instead of the standard filament end sensor, an optical filament end sensor is offered. It can monitor not only the end, but also its consumption in the tube, i.e. you can stop printing and not spoil the model if the nozzle gets clogged or the filament stops for other reasons. If you have a standard sensor installed (as in the photo), you can install it in the standard place - the mounting holes must match. In addition to the printed models, you will need any bearing measuring 16x8x5 (688ZZ). Standard U-shaped bearing used in 3D printers (photo). Optical end sensor, as in the photo. 2 M3x25-30mm mounting screws with nuts and 1 pc M4x10mm with a nut. The printer also needs to be modified to be able to use a pulse filament flow sensor. The "FS5_koleso2_TPU" model must be printed from an elastic material such as TPU or any other filament. It can also be replaced with 2 rubber rings of the same color. Good luck!
