  • The solution ended up being a setting on the printer that was overriding the firmware setting. I found the answer here.

    In case anyone is having the same problem, It seems that the settings stored in the printer overwrides the FILAMENT_RUNOUT_DISTANCE_MM in the firmware. So I just went the the printer configuration -> advance configuration -> filament and then I changed the runout distance and stored the settings.



  • Thanks for the reply, it’s good advice to try looking at the sensor as a unit by itself. I did take it apart because in some of the reviews, people said that the mechanism inside of the vase jiggles as the filament is pulled in and out during retraction. I ended up wedging some plastic from a raspberry clamshell container (cleaned). Inside, there are two bearing wheels, one fixed and one that compresses the switch. The lower wheel turns another wheel with slots like a wagon wheel with a light sensor on the spokes to detect movement. It seems to work like a mouse scroll wheel.

    There are 3 wires. From what I read, one is ground, one is +5v and one is SPI (from memory, I could be wrong). I can definitely check the switch part.

    I was originally hoping to hear from a fellow Ender user with a simple, “yes it works without modifications” or, “I followed different instructions to make it work”. In thinking through your post, however, I may flip off the motion detection portion of the firmware code and run it as a simple switch to see if that works as expected.
