3B-CoreXY motion platform
A new mechanism for driving a toolhead. I call it 3B-CoreXY motion system. The core idea was to shorten and simplify the belts as much as possible.
What we have is a system which uses three closed belts, and two motors. The motors work the same way they do on a traditional corexy system (see video). This system uses 3/4 the belt length of a traditional corexy setup, and arguably a much simpler belt routing.
