Printer stops extruding randomly

Here is something to read and to learn:

A350 printing "into thin air", no filament extruded

This sounds like user error. It is likely that your extruder gear is spinning as intended but the filament itself has had a groove ground into it by the gear. [image] This can be caused by a number of reasons as follows: Printing at too low a temperature, if you do this there will be excess pressure in your hot end which wont allow the filament to be extruded at the proper rate. Your extruder gear then over time grinds a notch in the filament and no longer can grip it properly resulting in…

What’s your filament?
What’s your toolhead?
What’s your print settings? Speed, Temperature, layer height?

I was using 1mm retraction at 45mm/s on the single extruder.
Was your filament grinded as shown in the linked post?
Or is it tangled on the spool?
Did you hear clicking sounds from the extruder gear?
