Talk:Geared extruder nozzle
Revision as of 15:06, 1 June 2011 by Reifsnyderb (talk | contribs)
is there a reason the teflon to brass interface is an M7 thread instead of an M6 thread? people already need an M6 tap and die to make the tip and heater block; why complicate it with a weird rare thread?

Reifsnyderb- In the original variation, the M7x1 threads interface between the PTFE and brass nozzle can be skipped. If it is not threaded, the tension created by the threaded rods holding the nozzle in place is enough to hold it together. Without the M7x1 threads, the PTFE is much stronger and is less prone to break.
