HICTOP HIC Technology Dual E3Dv6 Extruder x-carriage (Marlin Firmware)

Here is my new x-carriage for dual remote E3Dv6 Extruders. I have also had to redo the firmware (currently running Marlin-1.1.0-RC2 since it already supports MKS Base board used in this printer). I'm still working on fine-tuning firmware and I also have to modify the x-axis to allow wider range of movement so both extruders will cover edge to edge of the bed.

This is not a perfect design. It prints well, and fits together well, however if I were to redo it, I may combine some of the parts ra
