This is my DotG post processor for Mach3 laser operation.
Because the M11/M10 commands only operate upon axis movement and because DotG only produces it’s 'dot' output when the X and Y axis are stationary an imaginary B axis has been used to enable correct operation.
Within Mach3 the B axis is enabled and set-up with low step value - the Velocity / Acceleration can then be set to determine the ‘dot’ burn time.
Tweakie.
