Hi all, amidst a very productive printing session, that dxxxed PLA filament from some amazonic source got stuck in my hotend, well, in my printer's E3D-V6 hotend. After taking it apart and heating the block, I was able to carefully unscrew the nozzle. It's cavity was empty, the nozzle itself looks like a child boy's nose, dense with transparent material, nothing to worry about. The blocking, though, is obviously a few millimeters upwards in the heat insulator, that piece of delicate fine mechanistry that connects the heating block and the cooling part. The filament's path is locked with material. How can I get that out there without scratching or deleting the insulator? I've got some fine drill tips (1.7mm among them, pressurized air, and more. What is recommendable? Also with the aim of having a well functioning device again. I guess it got stuck there due to a somewhat too enthusiastic thermal regulation. I calibrated the PID parameters, but I found already that this new filament shows a different behaviour compared to the stuff I used so far - obviously, the dealer / maker went belly-up. Marlin's screen showed underswings of up to 2° C, maybe enough to hit on that steep slope between liquid and stuck. Is there some faq where this sort of problem is discussed already? I can't imagine that I am the only one experiencing this. Thanks in advance, and a very happy and sucessful 2016! Cheers, Ulli.
