Dual x carriage IDEX XY GANTRY

thingiverse

This is designed to be a BCN3D Sigma-like Idex system. Its design features four dual direct drive extruders that can be adjusted in height. I recommend using E3D Titan Aero or classic Makerbot clone extruders for optimal performance. If you need to make adjustments yourself, the Fusion 360 file is available for download as well. The main board should have six stepper drivers, but you can always add one more to a system like Ramps. The pins are used for E3 in pins_RAMPS.
