Installation

Either compile it yourself or use the appropriate release.

It should accept commands from most GCODE senders so long as they are on the right port and serial baud (9600).

The following pins are used as default pins in the code:

G0, G1: Linear movement command.
- Parameters: X, Y (mandatory)
  - X: X-axis position
  - Y: Y-axis position
- Optional parameters:
  - S: Set brightness
  - F: Set feedrate
  - Z: Laser toggle
G2, G3: Arc movement command.
- Parameters: X, Y (mandatory), I, J (mandatory for G2/G3)
  - X: X-axis position
  - Y: Y-axis position
  - I: X-axis offset for arc center
  - J: Y-axis offset for arc center
- Optional parameters:
  - S: Set brightness
  - F: Set feedrate
  - Z: Laser toggle
- Additional information:
  - G2: Clockwise arc
  - G3: Counter-clockwise arc
G21: Set units to millimeters (not implemented)
G28: Homing command.
- Additional information:
  - Moves to the home position (0, 0)
M0: Stop command.
- Optional parameters:
  - P: Delay time
M3: Spindle on (laser on).
