Interesting that Inventables doesn't sell this one. I wonder if they'll unveil it for the holidays? Maybe they've decided to go a different direction with Carvey and XCarve instead of keeping the Oko line alive?
It's just Sparkfun riding coat tails again. It's funny they call it a "deluxe kit" when it looks cheaper than the X-Carve upgrade kit for the Shapeoko II. And the Z is springs and belts instead of a ACME screw or even a threaded rod. If I remember right, this is the unit that spawned the Shapeoko II. I can't imagine why anyone would buy this over the basic X-Carve.
Some things are meant to be closed. Your mind isn't one of them.
