No extrusion during printing

Hello!

The k8200 i’m currently using recently stopped extruding any filament as soon as i press the “start print” button. Manually extruding works well, and it oozes when the extruder is heated up but not printing. Once it starts printing, it’s like it retracts the filament too far, and there isn’t even any oozing due to the heat.

I’m using repetier host v1.6.2 and cura engine for slicing; if anyone has any ideas what might be the issue i would be very grateful.

Thanks in advance
