Hi, someone has reported to me that their machine ( built with a smoothie board ) is having trouble with arcs output by my HeekCNC 1.0 CAD/CAM software. The output it is making is fine for LinuxCNC; using G2 and G3 with the I and J parameters defining the centre point relative to the arc's start point.
The smoothieboard documentation says that I and J are relative coordinates. Is this relative to the arc start point also?
Any ideas why the arcs might not be working correctly?
Can anyone give me some sample g-code with G2 and G3 moves which works correctly on smoothieboard, so I can produce similar code?
