How about creating a pen plotting mode? Like others I’ve 3d printed a pen holder and played around with pen plotting on my x-carve. It’s not hard to plot in Easel, but it would be a breeze if Easel supported it by providing a ‘Paper’ material and ‘Sharpie’ tool. Easel just plotting all the geometry projected onto a single ‘top’ plane. I don’t suggest spending lots of engineering effort on this, but if it’s not too much trouble it might be a nice feature to show off the machine.
