The Diamond Hotend is a product that has been around for a few years and my original plan was to build a machine from scratch around this part. After a few months of frustration with the performance of the M3D Quad, I decided to give the Diamond Hotend a try.
My setup uses some clone BMG extruders from overseas and relatively small OvertheMoon stepper motors from printedsolid.com. After committing to these spec changes, I am concerned that both may have been poor choices on my part. That remains to be seen.
I also chose to reuse the KF2510 connectors that are stock on the M3D Crane cable. Sourcing the female connectors, metal inserts and an appropriate crimping tool proved to be a bit of an adventure. But in theory I could switch back to the stock Quad head by simply swapping out the connections and reversing any systems setting customization.
As of this post, I have the hotend hooked up and tested but still need to add a part cooling fan and some fine tuning. I will try to follow up with a video update in a few days.
