Filament sensor not working
I’m not sure what or if I have done something wrong when putting together the filament sensor but I keep getting a message to unload and load filament. I keep unloading and loading filament but it seems to either not detect it or something because it will keep asking me to do the same thing over and over. This is frustrating as I can’t use the auto load filament feature. Any suggestions will be greatly appreciated.

Sorry, machine is an mk3s+
To confirm your diagnosis you can disable the filament sensor in the LCD menu - if it prints OK without the sensor then you've nailed it.
If so, look first at the plugs on the Einsy - are they seated correctly? pull and reinsert.
If no joy check there is no debris caught in the sensor, even a fragment of stringing can cause trouble...
Let us know how you get on.
Cheerio,

I have disabled the sensor in the LCD menu and it does print just fine with it disabled. What does this mean?
It means you are correct in thinking the problem is with the filament sensor circuit.
Check the sensor is clear, check it is correctly connected.
If no help test the resistance of the part with a multimeter. You are looking for a resistance, not an open circuit or a short.
Cheerio,

I have been able to repare and replace whatever needed with my MK3S+ (that I 💕 ) but the problems of the filament sensor I never managed to make working consistantly -apart from the very first months after I received it from Prusa). I disabled the filament sensor at least a year ago and have never missed it. It is unlikely you will have problems, unless you are careless with your filaments. I mainly print with Bronzefill of Colorfab (Prusa).
