Filament Stopped Extruding

My A1 Combo printer has stopped printing mid print on the same file 4 times. I’ve changed the filament over, albeit the same filament just a new spool.

Each time the print has stopped its start ‘invisible printing’. I.e, the filament stopped extruding, but the printer continued to move as if it was printing as normal.

I used a Eryone Silk filament PLA.

Video attached below.

Is the room with the printer warm?

It’s quite cold in there actually. It’s located in my garage.

I’m just testing a regular print file of mine to see if the same thing happens. But using a different filament.

Mine started doing this yesterday. I’ve taken the extruder unit completely apart, cleaned and inspected everything. Ive tried 3 different filaments, 4 different print files.

Ive tried a new .4mm and a .2mm hot end, and it still fails.

I’m not getting an air print error either.

So I’m pretty sure this was the filament. I’ve replaced multiple parts and tried different filament and error was happening. Very strange. Seems to only happen with this filament. :unamused:
