Use Wade's Extruder and you can skip the PEEK, because it does not need it. Two screws through the base of the PTFE will sufficiently hold the barrel.by katzlbt - Mechanics
Ok, here is my summary for nophead (I posted it on the Wade's Extruder Wiki Page too) I actually hand-drilled the holes using the detached drill head from my lathe. My black PTFE (carbon filled?) is very soft and easy to drill and I used a brand new drill. The holes should be drilled to 2.5mm, then you should insert the PTFE Insulator and drill a 2.5mm hole through both using the ABS part as guby katzlbt - Reprappers
Ok, its done and was not that bad. The drilling enlarged the holes in the ABS carrier and thread-forming with the M3 was not hard. It actually was really easy in the Teflon (almost no friction to feel). Unfortunately my drilling was a bit off so the hot end is not straight by a few degrees. But that should be ok.by katzlbt - Reprappers
Hi Nophead, Ahh, thanks. That makes sense. Its definitely your parts, they are very high quality. All screws just snap in. A job well done. Indeed, they are drilled to 2.5. I did not notice at first, but my 2.5mm drill fits through very tightly. I have a M3 tap drill, but do not like to use it on plastic, because it does not give good threads. I guess the task is to mount the extruder as tightby katzlbt - Reprappers
Hi all, I got my Prusa/Wade parts from Nophead and find it hard to mount the Teflon (PTFE) barrel. The instructions say that one should use a M3 for mounting, but the holes in the ABS are just 2.3mm wide. Wade suggests to drill the Teflon cylinder with 2.3mm. This seems awfully tight for an M3 that has a suggested hole size of 2.5mm for thread cutting??? How can I drill the holes correctly intby katzlbt - Reprappers
How can it work to use a 3W Resistor for 20W power? 12V and 6.8R = 1.765A this is 21.176 Watts?by katzlbt - Reprappers
Am Di 26. 7. um 19:00h werde ich einen halbfertigen RepRap zum IT-Syndikat/Hackerspace in Innsbruck bringen. IT-Syndikat c/o Cunst & Co; Tschamlerstraße 3; A-6020 Innsbruckby katzlbt - Austria RUG
Hallo Alex, Nophead includiert die Wade-Extruderteile im Plastikset. Die Düse habe ich schon selber gemacht. Bei Interesse kann ich euch auch eine machen. Und das Heated Bed ist Luxus, den ich erst nachrüsten wenn es funktioniert. Achja, und das Computernetzteil besorgt euch doch vom Sperrmüll, statt ein neues zu kaufen.

Ach ja: direktes Anschließen von Steppern geht nicht. Die saugen ja bis zu 2A Strom! Dann braucht man noch die Extruderdüse. Die habe ich selbst gemacht. Und einen 0.5mm Bohrer um €4, der in keine Bohrmaschine passt. Die nophead Plastikteile sind etwas teuer, die könnte der Erste der einen RepRap bastelt drucken :-) Leider ist mir ein Kühlkörper beim Testen umgefallen und hat den Arduino zerstörtby katzlbt - Austria RUG
