    I have a genuine E3D V6 Hotend for bowden tube and 1.75 mm filament, puchased from reprap.me. It has been working fine, but I have now started experiencing a weird issue. The hotend seems to clog, when printing slow. Whenever I get below ~20-30 mm/s, the hotend builds up a clog. It can easily be cleaned out by removing the filament, cutting the end sharp and pressing it through again. But the clog builds up quickly again as soon as I print slow.

    I am printing with Devils Design PLA filament, and I have attempted a broad range of temperatures from 185 C to 210 C - all with the same result.

    I have even disassembled the hotend completely and cleaned everything out. Still the same result.

    I hope you can help me out with some ideas of where the issue may be?

    A piece of filament withdrawn when the nozzle clogged. 2016-05-27 22.23.05.jpg

    Generally clogging like that is caused by poorly blended media. Too much of the colorant accumulates in the nozzle and causes jamming over time.

    I'd try a different brand.
