spindle speed is “whatever the router provides when it’s turned on”. I haven’t built any control for that yet. speed is fairly slow, but I don’t remember specifically what I set it to.
I’ve recently retired fritzing for sprint layout and the world is a much better place.
the workflow (most recently) is: Sprint Layout -> EStlcam (mill outside the line) -> gcode.
I posted the next board I created using this method and it’s significantly better than the first.
I’ve built a couple circuits in Eagle and just haven’t spent enough time to really get to know it. Sprint layout on the other hand, took me about 30 minutes to get pretty good at. plus, I have the addition of someone nearby that is also very good at sprint layout.
i’ll try to look up the federate when I get home…
