Hi! Does anybody have any experience with NURBS curves? I'm trying to create a closed curve. It's my understanding that with a uniform b-spline (i.e. all weights set to 1), the curve should close if I repeat the first two points as the last two points in the control point array.
However, the curve doesn't *quite* close, see screenshot below. Is this
just the way the implementation is (i.e. not really good for closed curves)
or am I doing something wrong?
Here's the gcode, followed by the curve as seen in Axis.
