    We've 'upgraded' a printer for a client with a Bulldog extruder and E3D hot-end but we're getting very weak traction and thus often slipage through the filament. Tightening the bolt's doesn't increase the gripping :(
    What could we do?
    Attached is the problematic weak grip of the bolt.

    Thanks in advance!
