Yea UK suppliers wont really help me, shipping is always an issue. Thanks for the offer though.

I have messed with the tension on the hobbed bolt, I have had it pretty tight before, to the point its putting pretty deep notches in the filament.
Not tried it SUPER tight before, read that you dont want it digging into the filament super deep.

When it slips, it eats a grove in the filament, and can no longer grab it to feed it, so,, the print continues with the printer not extruding.
So yea, frustrating, cuz that ruins every print that it happens on. I have had it happen after 5 minutes, and 5 hours.
