I continue to flounder with extruders. I started with QU-BD and have moved to Bart's modifications, Makergear, and J-Head. J-Head seems to be the rave. I can't get it to extrude though. Without the hot end, you can barely hold the filiment from moving with two fingers. But, I have difficulty getting any of the filiment to go through the extruder even when assisting with fingers. I bought two of the J-Heads for 1.75mm.
Upon disassembly of the extruder I found that I actually had some melted plastic sticking back out the top! I got the head hot and pulled a piece of plastic out of the extruder that is 3.2mm in dia. I checked the unused extruder and the tube going down into it is over 3mm in dia.
Does this mean they sent me the wrong hot ends?
