Re: Slots/elongated holes

Danny Miller <dannym@...>

What's with this "no circles" thing, anyways?

I'm not gonna trouble myself or you with complaining about free software.  So don't take it as complaining.  But I'm kinda wondering what's so hard here... the gcode for circles is just a type of arc, it should be implementable.  PCBGcode's has some upgrade work since then, can't it be fixed?

Circles aren't supported, but you can use two arcs to make a circle.
Arcs work correctly. There are several in the set of boards I made, as shown in the pics I uploaded.
Let me know if arcs work for you.

Jj did you come to fixing the arc/ circle bug? Im making a ringlight
