Filament does not come out of the nozzle any more
Greetings!
I am using a Prusa Mini+, filament is high speed PLA, diameter: 1,75 mm, nozzle: 0,4 mm
and after yesterdays filament change, nothing comes out of the nozzle any more.
I have tried to repeat the filament change a couple of times, stuck the needle fully into the nozzle, took the nozzle out and tried the filament change without the nozzle, that worked. Place the nozzle and tried again, nooo!
What do I need to do?

Thank you Diem,
have tried this repeatedly, exchanged the PTFE tube, material comes out without nozzle, but despite cleaning the nozzle before, nothing when that one is in. Guess I have to exchange the nozzle ?
Remove the PTFE delivery tube - you are going to feed directly to the print head ...
Move the head close to the Z axis to reduce strain.
Heat the nozzle to at least 10° above the hottest printing filament you use.
Take 50cm or so of PLA and, by hand, push it down through the print head - it may take some force at first - if it does feed push the filament slowly at first then accelerate to as fast as it will go - finish by pulling the last few cm back out as fast as you can.
If it doesn't feed, you have a ruined nozzle.
Cheerio,
