ERR: Failed to extrude the filament. Check if the extruder is clogged

Hi.
That night I printed my project and in the morning time saw at panel “Print completed”.
But in real only 30% was printed.

After I try to print a new project.

When the filament moves to the head I hear some tick-tick-tick sounds and after a few seconds filament moves back to AMS.
Then it starts again: move filement to the head → tick-tick-tick → move back.
And 3rd time again.
After 3rd time I see the next error:
Failed to extrude the filament. Please check if the extruder is clogged. After troubleshooting, click the “Retry” button. [0700 8007 105215].

I thought maybe a problem with the nozzle.
I have a new one and I replaced it.
I start printing a completely new project again.
Looks like it is okay but when it made calibration lines and started to print the item - no filament was extruded at all!

Then I try printing a new project again → and everything starts again!
Move filament to head → tick-tick-tick → move back… And repeat…

How to fix that?
I use standard PLA Green Sparkled filement.

There is a video:

Thank you

More than likely an extruder clog.

I Have the same problem.
I change my hotend and i test to do benchy, it’s done :slight_smile:

I changed it 4 times.
And made all kinds of recalibrations and tests…
After that, it starts work. But it’s very strange :frowning:
