Hey all, Just an update, I swapped out the old jhead for an E3Dv6 and the problem went away, so it's either in the old hot-end or an interaction between it and the rest of the system. I'm planning to dissect the jhead and see if there's any explanation there, but first I'm going to use the new hot end to finish printing a spare printerby jjg - Printing
Finally got my Prusa operational again so I can print the remaining Tantillus parts. As the final printed parts roll off the line, I'm anxious to get started assembling, but I'm wondering if I can roll with what I have, or if I need some more minerals. In particular, do I need the "real" linear bearings inside the carriage or can I get away with printed ones? Secondly, the drill rod I have forby jjg - Tantillus
CAD software is mostly OpenSCAD, but I've tried models I've created myself in Tinkercad, and models created by others from other software as well. Good call on the Gcode visualization but the models look correct in Gcode visualization as well.

After the firsby jjg - Printing
Excellent article, just what I was looking for! I had thought this was a fairly "solved problem" and was considering slapping a syring-based extruder on a printer whose plastic extruder had failed, but apparently it's not quite that simple You mention that commercial Moineau pumps use a stainless rotor and rubber stator to maintain a better seal than is possible with a printed unit, however coby jjg - Paste Extrusion Working Group
