Nozzle block prevention tip

Recommended Posts

Hey fellow UM'ers just thought Id share this little tip. I had a few blockages with both my UM1 and UM2 in the past, I always wondered 'how is material getting into the nozzle to cause blockage?'

So I took a small piece of sponge material, and pushed the filament through it before it goes into the extruder, then attached it to the extruder with a rubber band. This means it it cleans the filament as its pulled up into the extruder. No blockages since !

I've had this little mod on both my UM1 and UM2 for 2 months now and done a fair bit of printing so I do think its working !

(UM1 is for sale in the for sale section If anyones interested !)

Unfortunately as it happens, most of the tiny pieces of cr*p that get on the filament in a UM2 come from internal wear on the stock feeder, which accumulate inside it and cannot easily be removed.

So I use the same hunk-of-poly-foam technique (you don't really need the rubber band), but with Robert's feeder, which does not shed plastic particles and is easily cleaned.
