I am no expert but my 3d printer is acting very odd. It does not extrude when printing, and when I lean in close I can smell something have been burnt. I looked up online, apparently I can unload the filament and look at the end to determine whether the nossle have clogged. But when my printer unload the filament the stepper motor just makes lots of noise, I think the filament is stuck in the nossle. Help! What should I do? (I am printing with regular pla)

What is the temperature in thé status screen while unloading thé filament ?

The temp is 210°c

Can u try to pull out the filament manually? Just heat thé extension a bit more en disconnect thé guide tube on both ENDS and try to pull it out?
