CNC Arduino Shield

Specifications:
• Enlarged board to add a 4th Axis that can clone the X, Y or Z-axis. With a 4th option to use pin D12-13 to control it.
• Added a breakout header for all the Axis’s
• Added a communication header for UART(Serail) and I2C
• Added a connector for an optional fuse. (Fuse not supplies as it needs to be selected for the current that will be used.)
• Capacitors are mounted horizontally giving more clearance between them and the stepper drivers. Good for ventilation.
• Added a pull-up resistor on the axis enable pins. This prevents the pin from being in a floating state
• Added 2 mounting holes
