This is one of the first versions of the E3D mount for my Huxley. I took a 4 year hiatus from printing letting my Hux collect dust. We needed to prototype a few things for a different project, and were having major issues with the original hot end. We opted to buy the brand named E3D v6 Lite Print head because of the great reviews. This mount was created as a first draft. We plan to develop the mount as issues arise (and I'm sure they will). Please keep that in mind if you plan to use it or remix. This part is under heavy development.
We used as much of the original Hux X mount as possible. We re-used the mount screws ,but did have to purchase a few bolts to hold the mount bracket together. The one from the pictures was printed in PLA, but ABS may be a better solution because of the proximity of the first two fins (that get ~35C-40C when printing with ABS.)
The E3D V6 Lite comes with a significantly larger PTFE tube as the original eMAKER Huxley. We have also created a remixed version of the rays-jones bowden extruder that includes a spot to mount the new fitting from E3D.http://www.thingiverse.com/thing:1365834
A word of advice after configuring Slic3r for the new hot end:
We had the 2011 model with the .5 nozzle so a lot of slic3r settings changed when we moved to the .4. Slow the the first layer WAY down. We were getting bubbling (and still are to some extent).
Our first theory was the airflow of the hot end fan impacting the cooling in unintended spots. E3D recommends leaving the back side of the fins open for airflow, but this was not an option because of the form factor of the Hux.(check the comments there is a solution for this issue in development by another maker) After testing, we realized that the fist layer was printing way to fast. We changed the print speed to 30% for the first layer increased the width of the first layer to 125%.
Revision History
Revision .93 Initial Development model. We would like to address the following issues
-unintended fan air flow out of the bottom of the hot end
-vents to allow lateral airflow
-delete screw holes on the small piece
-mount a 3m ptfe sheet on the bottom of the fan to protect against heating from the heater block
Please comment on issues if you think of something we would love feedback
