fan works but keeps switched off

Hi,

I have odd problem. I used MK3S successfully for several months.

Now front fan on the extruder unit (tilted one, the one that blows the air in the printing area) does not work.

Actually it works, it is not broken, it spins during selftest, but it just keeps off during printing.

It is confusing and frustrating. Even the prints I did before fail now. Obviously, because the nozzle area does not get cooled down.

Any ideas, please? Anybody with similar problem? 

Thank you

Check in the slicer setting so that the fan has not been switched off accidentally.
If you print with ABS, the fan should normally be turned off but on other materials it should be on.

Bear MK3 with Bondtech extruder

@rhdreambox

thank you.

I checked, it was not the case, however logical that would be. I did full reset and now it works normally. I do not know what was the reason, but it works, so that is basically all that matters. Thank you.
