Project Group Picture
As a result of the system design, the team was able to develop a functional CNC controller capable of:
- accepting and parsing GCode paths
- controlling an arbitrary CNC machine
- using closed feedback control loops.
- running on a bare metal environment on the RaspberryPi module.
The controller currently requires the use of the AS5161 encoders, coupled with diametric magnets on the motor's shaft. However the system was designed modularly such that as long as position feedback was given, the system would be able to do precise position control with arbitrary motors.

Actual Result
As shown above, the CNC was able to follow the path constructed by the following GCode.
