Hi Desert Eagle,
Welcome to the forum.
DotG was originally intended for impact engraving so the actual ‘dot’ is produced when the X axis is stationary. The axis motion is basically stop – start. To enable DotG operation with a laser then a dummy axis (axis B) was used to trigger the M10/M11 commands. This article attempts to explain the M10/M11 commands and how axis movement (any axis) is necessary for their operation.

ftp://anonymous:guest@ftp.machsupport.com/Mach3/Mach3Version3.043.062.exeThe plugin delay, after the movement to the left, is something I have been meaning to correct but, like so many other things, it never happened – perhaps one day I will do it. You can make a reduction in this delay by operating the plugin in constant velocity mode.
The plugin writes directly to the Mach3 engine so no separate Gcode is available for viewing or editing.
The plugin uses a constant 40uS pulse width (this does not change) it is total number of pulses per pixel (determined by the pixel value) which regulates the laser power or burn.
Hope this helps.
Tweakie.
