CR-10 V3 filament sensor does...nothing?
I've got a CR Touch so I've flashed both the V2:
firmware (which both say right in the filename that they do filament checks), but neither seem to actually do filament checking.
I can put filament in, the sensor turns blue, I issue a M119 and no sensor switch is detected. M412 just says 'ok'. I pull the filament out, blue light goes out, controller seems blissfully unaware.
I just had my first actual filament runout (due to a filament snap) today, which is how I became aware it's not doing anything.
What should I check next? What's the expected behavior and how can I test for it?
Take apart your filament sensor (really easy) and bend the arm just a tad more to connect to the filament a little more. Thats all that is needed.

hi，@rhester72 You can update the firmware below, and then test whether the sensor can work normally
If it still does not work, it may be the sensor is broken, please change a new one.
