as if it were a Litho Plane… In Artcam (cnc program) you can load a bitmap image, and say , black = 0mm, white=4 mm deep…
and then you can do things like this:
so with black you do not remove anything, so that remains dark, with white you remove 4 mm, and if you shine light through it, it becomes lighter…
so I’m making a toolpath like that, only the other way around… I say, with white you mill 0mm deep, and black 0.00255 mm deep…
and then instead of letting the z-axis go up and down, I use here for another axis… with which I control the PWM of the laser.
and it’s getting better…but just for fun looking at how i can improve my workflow so that it becomes easy to get a good result…
