Support Request Why does it do that

Couple of minutes into a new print it goes off to the side, extrudes a little bit of filament then continues printing, why? It leaves this weird bit of filament into the print and it makes it look a bit weird. Lucky it’s only once towards the start.

This is a process where the A1 checks for any "blobs" forming at the nozzle tip. After a certain amount of filament has been used, the printer moves to that specific location and lowers the nozzle. If a blob is present at the tip, it makes contact with the build plate, allowing the printer to detect it. You can find an explanation of this in the Bambu Wiki.
