This is an adapter to mount the E3D v6 1.75mm bowden HotEnd (dual) on the K8400.
This is a new design!
Try it.. and tell if you like it.
Release early, release often.
This part replaces the EXTRUDER MOUNT PLATE on the Hotend.
Assemble it in the same spot, but don't replace the original EXTRUDER MOUNT PLATE.
Do not remount the SMALL FAN MOUNT or SMALL FAN, these will be replaced by the E3D FAN/DUCT, mounted directly on the E3D v6 Hotend.
Connect E3D FAN/DUCT to the powersupply, direcly. If your setup is the same as mine. There will be free 12v connectors.
Carefull, high voltage... be sure to connect to the right connectors and only work on your power supply, while it is disconnected from mains.
The current setup is a little wider than the original. Your X home function, may or may not function correctly. This will not affect the quality of the 3D prints.
I extended the endstop finger, by glueing(CA) a small strip of try-rap to it (about 2cm)
Offset between hotends, should be 31.0 mm, but adjust to your own findings.
