My 'Scribbler' (named in part for it's original creator and the fact that I have it set up for fast, sloppy prints) is the easier fix as I can fix it with tools and not printed parts.
I've only had the parts for maybe 3 months? Finally got to modifying the bits so they work together.
It's amazing how much better buying a few parts for a few bucks works.
I machined part of the sholders off on the brass fitting so it would sit in the carrier and made a plastic nut. The intent is that it matches the groove mount that the EZstruder can work with so well.
The bottom piece I just drilled out with a varibit, reamed a bit with a flat screwdriver and pushed hard to get the NPT threads to bite into the plastic. As long as this bit doesn’t get hot enough to soften the PLA I think I should be fine.
A google plus auto-awesome animated gif. The right #3DBenchy failed due to a loose connection on the extruder wiring. The left one is my 2nd successful print with the new feed system. The current print is a few tweaks to get it to print faster, better.
