Well I have upgraded to Marlin and moved the head closer to the bed by adjusting the Z-axis, it was perilously close before, now its probably even closer. It managed to print a test cube, will try the whole cleaning thing, but my the plastic peek insulator is plastic on mine and the brass thing will not come off anymore?

Hey all, I am writing here because between me and two friends we've just about at our rags end trying to make this blasted thing work. The assembly all went well as far as we can tell however we have a number of issues and have only manage to print 1x 20mm cube and 2 bits of a 20mm cube, most of the time it doesn't work well enough to print anything except drippy plastic... Issues: 1. Brown gunk Despite being very careful about the length of the tube and fully reassembling the extruder head, we still occasionally get brown gunk come out of the space between the metal block and plastic tube. I am not worried, but why is it doing this? 2. Temperature accuracy It seems that my Ultimaker is chronically under-temprature, I have been watching it whilst writing this post, it's set to 215ºC but never seems to deviate from 209ºC. Again not major concern but I worry it might be loosing temperature during extrusion. 3. Extrusion This is my main issue, it seems like the extruder is rotating and pulling in material but not really extruding any, or that plastic runs out by its self when the motor isn't running, and it seems that the ReplicatorG control panel doesn't work so I can't seem to get things setup. We're all super disappointed by our new gadget, we really hoped to have something coming out by now, but we've either missed something or there is something wrong with what we are doing. Please help!
