Broadway is an aluminum 80/20 frame CoreXY 3D printer ( 600x600x900) print area 420x420x 800 using ramps 1.4 with mega 2560 and Repetier Firmware. Found many of 3D test projects here to test the 3D printer. This was designed for 3 side by side J-heads with bowden tubes using only the center one as adjusting 3 printe head heights was dontaing. my design uses 3 driect drive z motors with 3 aluminum hangers. Changing out ramps for MKS currently have 3 colors of extrusion with anycubic Bulldog extruders (have plans for 6 extruders) going to upgrade to the Diamond this way i can switch colors by only changing the extruder motor # and the bowden tubes. (6 colors) with 3 to the Diamond head of course you can only use 2 colors at one time. But what if you had 2 diamond heads and 3 more colors.
