Autoload suddenly stopped working after almost 2 years
I've had this MK3S+ for a little under 2 years. Just now after an about 18 hour print with PLA that went off without a hitch, suddenly it doesn't auto-feed. Does anyone have a good set of debugging steps for the filament sensor? What I've found so far on the web is mainly for problems that occur during assembly. I'm looking for how to debug a problem on a printer that's been working a while. Many thanks in advance.

Thanks--I saw that one. It seems to be more directed at initial assembly. The one part where it is directed at after assembly is continuous firing with stuck filament, which is the opposite of my problem--it's not firing at all. It just suddenly stopped firing. Is there any other place with more information on how to debug a sensor that stopped working after a while (in my case, almost 2 years)?

Navigate to LCD Menu -> Support -> Sensor info and see if the 'Fil. Sensor' value (1 or 0) when adjusted. 1 = fil. loaded, 0 = fil. unloaded.
If the sensor value is pulsating, try to calibrate it.

It's reading 1 whether or not there's filament in there, so I'm guessing that 1 indicates no filament seen by the sensor. Any ideas how to proceed next?
RE: Autoload suddenly stopped working after almost 2 years
1 means it thinks filament is already present. There are numerous threads and resources on the forum already about dealing with dodgy filament sensors. Essentially though they all require getting to the sensor and checking it is still assembled correctly and not gummed up with crap.
