In the initial post it says 170°...
Do I have tso suggestions for you as I am suffering from the same problem!
- I noticed that lots of cooling helped somewhat - but also increasing! The print temperature to about 210- 220° which was more then I usually printed PLA at. Whoch software are you using?
In Slic3r try to adjust the "external perimeter width" - try to go bigger then your nozzle diameter.
changing this from about 0.4 for my 0.4 nozzle to 0.6 or even 0.7 or 0.8 on steep overhangs did the trick for most of the parts I was having trouble with.
also you want the air not just to be pushed all around your hotend with severyl 120mm fans bit to be directed exactly where the fresh extruded plastic xomes out of the nozzle.
i also insilated my heaterblock - so it will not react towarda the nassive cooling with heating upnunevenly...
a small layer of high temperature silicon is what I can recommend.
that red stuff is heat proof to 260° or 300° for shorter times.
hope this helps a bit.
please post your results,
Alex
