Hi all, So I have had my E3Dv6 for a couple of weeks now, and it has worked pretty well on larger prints with PLA and ABS. The problems happen when I print something small like 3D Hubs Marvin in PLA. I am not sure , but I am thinking because of the slow feed rate and frequent retractions, some how it gets jammed and the filament strips. I have tried retractions between 0.5 and 1mm. I am using a Makergear M2 and am using a 30mm ball bearing fan which I think provides good cooling. I am using the following drive, heatsink shroud: http://www.thingiverse.com/thing:344950 I believe it provides good cooling. I am using a 25W E3Dv6 with 1.75mm filament and direct drive, on a 0.4mm nozzle. Larger prints like I said seem to print without any issues at all, and I have done loads both in PLA and ABS. But it's only smaller ones, like Marvin and 3DBenchy, which give up about half way through, because of stripped filament. But I have only tried PLA. Will report back soon with ABS. Please help. Its driving me nuts. thanks, loiphin.
