Brassfill Issues anyone?

[Joelistics 0]

Hi guys,

I have been having issues with brassfill from colourfabb while printing from my UM3.

Every time I print, the print goes well for the first 10-30 minutes. Then for some reason the feeder grinds the filament and snaps it at the feeder. Either this happens or the filament simply snaps by the feeder, I am not sure.

I know brassfill is very delicate but it should not be this delicate right?

Has anyone else had this problem before? Or has an Idea how to possibly solve this? - I am new to 3d printing
