No filament coming out !!!

Post by shaker_khanfar » Fri Oct 19, 2018 9:06 am


I bought a Mini 2 two weeks a go and it was printing fine, it suddenly stopped printing. I checked the motor and it's working fine. I tried unclogging the nozzle and some brown material came out of it (i'm printing with wight ABS). When i start extruding, the filament goes in and then the motor starts making sounds as if the material is stuck and can't go in anymore.

Any suggestions ??

try to clean the nozzle first, and also clear the extrude gear inside the extrude head,the brown material is the melt and sorched ABS material

I am having the same problem. The nozzle is not clogged. The ABS filament feeds in just fine and will extract just fine. It acts like the clog is before the the extruder. How do I clean that out?

Are there any videoes or instructions on proper cleaning? I've seen some links to a video which is no longer availabke.

Just had my fist clog today after making around 4kg of more or less failed prints and rafts :P.. "Cold pull" of filament didn't seem to do the trick for me, ended up removing nozzle and running some filament through the heatbreak and then pulling out a cold clean plug from that and installing the spare nozzle while the old soak in some acetone.

Both nozzle and heatbreak had a liner of old ABS that didn't melt properly greatly reducing the flow, but a little dismantling and a new nozzle did the trick. Not sure if that is the correct method, also not sure about the whole "heat nozzle up past printing temperatures and give it a good tighten before letting it cool down" thing, to prevent it from coming loose when expanding from normal printing temperatures?
