Feeder problem

Does anyone know what is wrong with the feeder on my UM2? It pushes through some material and then looses grip and slips so it generates a knocking noise.

I double support the idea of putting the filament on the floor (or below the machine). Using good filament, moving my spool below the printer, using ball bearings in the spool holder solved all of my feeder issues.

In general I agree, using bearings in the spoolholder myself.

however with some filament you get spools unwinding them-self due to the lack of friction... so I'm looking forward to upgrade to the geared feeder, think I'll try the old plastic spoolholder again then...
