Filament sensor

For some time now, it has not been possible to print with the filament sensor enabled because the print constantly pauses, accompanied by a beep indicating that the filament has run out, even though there is still material available. It never used to happen before, and now I have to print with the filament sensor turned off, as it is otherwise impossible. What could be the issue?

RE: Filament sensor

the filament sensor could be out of adjustment, 
Or, 
the filament path could be worn. 

which version of printer do you have. 

 

with use the wires could have fatigued and failed, perhaps intermittently.

I haven't touched anything to the sensor since it was new, the printer reprinted for about 30-60 days.

This is MK3S

RE:

mk3s filament sensors sometimes need a thin plastic washer under the filament sensor, there are examples on thingiverse.

RE: Filament sensor

Sorry, I have no idea. 
It will take moments to print and test...
I have had Mk1, Mk2, Mk2S, Mk3, Mk3S, Mk3.9, SL1 and SL1S, but not Mk3S+

So first off loosen the fillament sensor screw slightly then when inserting the fillament you should feel a bit of resistance you should also be able to see a metalball down through the hole. Also reseat the connections both ends.

Please help me out by downloading a model it's free and easy but really helps me out https://www.printables.com/@Hello_474427/models

RE: Filament sensor

Mk3s+

Added ease of building. No real benefit  if mk3s is performing well

Turn automatic loading function off. Then open the filament sensor menu and check the status "on" or "off". Then insert filament and watch whether the status changes. If not, loosen the screw of the filament sensor *cover* half a turn and try again. ((Actually I am pretty certain I remember that the cover screw tightness is the culprit, not the sensor screw tightness, but the others may well be right; the process described is the same for the filament sensor screw). Repeat until switch is reliable off/on when removing/inserting filament. Then support the sensor cover with a non-conducting material washer, as proposed above, to allow tightening the cover screw without putting too much pressure on the sensor. through the tightened cover.
