   *   LASER_POWER sets the laser intensity (uint8 opcode, uint16 power)





daan

1:578d6bbe9f09


    27

   *   we can extend if we need color.

    29

   *   (not implemented) FAST_MODE (uint8) Sets the laser in fast mode.





daan

1:578d6bbe9f09


    30

   in fast mode, the motion commands will be set, and the galvo goes to the new position





daan

1:578d6bbe9f09


    31

   as fast as possible.





daan

1:578d6bbe9f09

   ----- slow speed ------





daan

1:578d6bbe9f09


    35

   *   (not implemented) SLOW_MODE (uint8 opcode) (default) Sets the laser in slow mode.





daan

1:578d6bbe9f09


    36

   in slow mode means that we go step for step over each pixel with a line raster algorithm.

daan

1:578d6bbe9f09


    39

   *   STEP_SIZE (uint8 opcode, uint16 size) sets the galvo step size when drawing lines.





daan

1:578d6bbe9f09


    40

   using cheap optics and a short throw the laser spot size is probably a few orders of





daan

1:578d6bbe9f09


    41

   maginitude larger than the theoretical step size of the galvo. This parameter allows





daan

1:578d6bbe9f09


    42

   you to control the step size when going slow.





daan

1:578d6bbe9f09


    43

   





daan

1:578d6bbe9f09


    44

   *   STEP_DELAY (uint8 opcode, uint16 delay) sets an optional delay when drawing each pixels.





daan

1:578d6bbe9f09


    45

   this is sometimes neccesairy for extra illumination of the surface.
