Horus 3D Scanner Firmware

Modified from the original firmware by Gyrobot to work with the Arduino UNO and CNC V3 Shield.

• Motor is driven by "X" Pololu driver.
• 12V power supply <1A to CNC V3 shield required for motor.
• Lasers are fired by "Z.STEP and Z DIR" pins.

This firmware is written in C.
