Filament sensor with a button to trigger print pause/filament change
Description
Another filament runout sensor, which contains an adjustable sensor/switch position and an override button to pause the print, instead of going through the menu in the controller. The filament can be slide in both way and the sensor can be moved away when not using it. The hinge of the mount was assembled with a piece of filament and melted with glue gun on both ends. The included frame mount is for the Tevo Tornado, so you'll probably have to make your own frame mount. The schematics included is for your reference only and the board file is to help optimize the soldering of the wires. Since I'm not an electrical engineer, you'll need to make up your own circuit if you see any issues with it. Use short PTFE tube, one M5 bolt, 2 M5 nuts, one toggle button, one 3mm LED and 2 resistors(500~1K for LED, 10K~100K ohm for the button). The switch I used is probably KW-11, but not exactly sure. Also I have modified the final design from the result of my print, but I have not reprint it to see if everything still fits. Will do it when I need to retrofit the other printer later.
