Hi Just registered to say I am really pleased, My printer is self built but most of the hardware came from a 3Drag kit. Since I have had it I have been using a .5mm J Head hotend but I wanted to get into ABS and Nylon and the PEEK on my J Head had started to fail after about 100 hours of printing PLA, So I thought I'd give the E3D a go. Bought one from E3d-online, went together nicely (whilst munching the provided Haribo sweets ) and everything seems really good quality. With a custom mount it goes nicely onto my 3Drag extruder. Figured I would have a night of messing about before getting good prints again but no...I was already using a type 5 thermistor so I just reset my slicer to use .4mm. Recalibrated the Z axis and first PLA print came out great ! Can't wait to start trying other plastics without fear of meltdowns.
