[extrusion problem, atomic method doesn't give solution]

I tried the Atomic method another 4 times since I posted the last image of the filament after the procedure and it seemed to come out less messy all though not as perfect as I see on demonstration pictures. I tried to print a model (figurine) which went well for a while but halfway the problem reoccured. Thin, crusty layers and a lot of 'hair'. But some parts are printed well. I am using Simplify3D. Temp. 210º, Building plate without heating. I already cleaned the filament feeder. Should I replace the nozzle?

[extrusion problem, atomic method doesn't give solution]

Hello,

I am experiencing extrusion problems. Very irregular prints with PLA. So I tried the Atomic method to clean the nozzle. But the filament comes out with a strange dent. Any idea what is wrong here?

Thanx in advance.

Thanks! I found it.

Thanks, the gap wasn't too big, there was nothing flowing at all, even not before the nozzle reached the bed.I refer material again and then it came out. I had a look at their site, but don't see an English version, I am overlooking something?

Cheers!

Thanks, I will try but for now I ran into another problem: the filament (PLA) doesn't come out. So I refed the material. It seemed to work at first, material coming out from the nozzle while feeding. But when I started printing again, nothing. Can the nozzle get clogged?

Out of the box I printed the Ultimakerrobot and it worked fine. Since then I can't manage to make good prints. I tried the robot again but now the filament curls up around the nozzle and/or doesn't stick on the plate. I recalibrate the bed and am printing with factory settings. The filament is black PLA.

What can be the problem?
