The X- and Y-axis are both operational. I did some tests, and used the mill as a very expensive “spiral drawer” 🙂 I did put a drawing marker in the mill-attachement, and loaded a spiral example into Mach3. The chirping and creeping sound in the movie, is the drawing marker, which is pressed hard to the wooden panel. (The drawing marker is almost empty)
