Build objective is to maximize build area (XY) without reducing precision and reliability. Build dimensions are 36" (X-axis) x 36" (Y-axis) x 6" (Z-axis). X and Z axes are integrated by fastening gantry plates together and intended to remain fixed to a workbench or frame for maximum rigidity (Currently installed onto my custom built workbench). Y axis is built similar to C-Beam machine, but inverted such that the drive screw is shielded from dust and cuttings. Additional 20x40 linear rails with Mini V Gantry sets are used as support wings to balance the build plate along cut line.
Control box is built to minimize and simplify connection points. The 18"x7"x3" box houses the 600W 24V power supply, BeagleBone Black with CRAMPS cape and 3x (up to 6x) Pololu DRV8825 Stepper Drivers. Connections for each axis include motor and max/min limit switches which are all pre-wired inside the box and output to a single Aviation-style 16-8 (8-pins) connector. A 5V/10A regulator/converter is used to step down power from the 24V power supply for auxiliary use and run the BeagleBone Black.
