| The laser is controlled by sending commands ("g codes") to it via USB->serial connection. Additionally, the laser control electronics can read files containing these commands from an inserted SD card without the aid of an attached computer. | The laser is controlled by sending commands ("g codes") to it via USB->serial connection.

| There are several ways to command the laser to fire: | There are several ways to command the laser to fire, each is enabled or disabled at compile time, according to the following option in Configuration.h: |
| - G0 / G1 (**default: on**): enabled by the LASER_FIRE_G1 option in Configuration.h, G0 moves the laser to a specified set of coordinates __without__ firing, a G1 command moves the laser to the specified coordinates __while__ firing. | * LASER_FIRE_G1 (**default: on**): G0 moves the laser to a specified set of coordinates __without__ firing, a G1 command moves the laser to the specified coordinates __while__ firing. |
| - M3 / M5 (**default: on**): enabled by the LASER_FIRE_SPINDLE option in Configuration.h, M3 turns the laser on in place, without requiring it to move. M5 turns the laser off in place. | |
| - E movements (**default: off**): enabled by the LASER_FIRE_E option in Configuration.h, any movement in the E axis (which represents the extruder when controlling a 3D printer) fires the laser. In this way, the laser can make use of unmodified g code generated for 3D printers. | * LASER_FIRE_SPINDLE (**default: on**): M3 turns the laser on in place, without requiring it to move. M5 turns the laser off in place. |
