Posted · Grinding Filament

The past day or so my Ultimaker has started grinding the crap out of the filament.

I've tried clearing a blockage, so I know things are clean.

I've tried different filaments, ones that I know used to print just fine.

I've also tried tightening, and loosening the screw that puts the pressure on the filament and the knurled bolt.

So far, nothing has seemed to fix the problem.

It seems to start out printing fine, but soon starts grinding the filament to the point that it will no longer feed.

Any ideas on what else I can try to see if I can get past this problem?

    Tiny pieces of dust or wood that are difficult to see can cause partial blockages. That's the most likely problem. Best fixed by unscrewing the nozzle (gently! and while at 200C! Consider using oven mitts as you are less likely to damage it) then heating the nozzle with flame to burn anything in there out. Not so hot that you melt the brass.

    Alternatively is it possibly you have been increasing layer thickness or speed recently as the volume of filament that can pass through the nozzle is limited so if you switch from layer height .2 to .3 you will hit this limit likely or if you speed up from 100mm/sec to 150mm/sec with .2mm layers you can also hit htis limit.
