Hey guys, I'm almost through a spool of Colorfabb XT-CF20 mainly printing small parts. Today I had a 3D Hubs order with some big parts that took up to 6h printing time. I always noticed the blob of filament on the nozzle while printing with XT-CF20 but it never turned into a problem until now. The blob only grows while printing and when it becomes to big it drop right in the print. When the head passes again it crashes into this blob resulting in the motor skipping steps. Ruining the print, offcource. I've read about this problem on the internet and also hear on the forum, but I've never found a clear solution for it, if there even is one? I've tried printing slower, different temps, retraction,... Nothing helped. I have an E3D Hardened steel nozzle, 0.4mm. Would a 0.6mm make any difference? Are there people that do not have this issue, what are your settings? Thanks allot in advance, I'm desperate... Andreas

Is there anyone that has a fix for the filament that sticks to the nozzle? When printing my nozzle is full of filament and drops it right into the print, later crashing into it and skipping steps. Making this filament unusable for prints longer then 1h

Is there anyone that fixed the issue with the blob being on the nozzle all the time while printing this filament? I'm sick of this filament. Everytime I have a +1h print it drops blobs into the print, crashes and skips steps. I've tried different temps, different speeds, different retractions but nothing seems to help.
