Surfacing in spiral pattern problem

I just ran the surfacing function, and it left a mohawk strip, 6mm wide, down the centre on my board where it didnt cut. Anyone else seen that? Ver 1.06.

This is pattern the system generates, the gap in the middle is noticable in the visualizer

From my shed cam, you can see the line in the centre of the board.

@tgerdes Is the uncut strip 20mm wide by any chance?

No, it was about 6mm to 8 mm wide. Almost like it calculated the stepover incorrectly.

@tgerdes You may want to see what the visualizer shows if you reduce the step over.

Thanks for the report, we should have a fix for this in the next build - given your original inputs, the gcode generation should now properly finish the center of the board using the spiral pattern.
