Grumpy_Mike:
In what way was that different than the method 2) I described?It is virtually identical to Gcode.
I'm not quite sure what you mean by "method 2" but I had the impression from Reply #14 "No one has said anything about turning a bit mapped image into a vector image" that you were talking only about drawing from vector images.
It is different from GCode to the extent that GCode has to be interpreted and actual coordinates for stepper moves do not.
