> It seems a CoreXY or H-bot design, I always believed that the issue with this design (like any cartesian design) is with the limits of acceleration and "drag" of (relatively) massive parts
there are enormous multi-ton machines which can move faster than tiny little delta printers.
delta printers are good at maximizing speed when you have constraints like price, noise, weight, "fits in my home", "uses single phase residential power" and "cannot literally tear my limbs off". don't confuse the constraints of consumer printers with the constraints of industrial machinery, which is what it looks like these folks are trying to design.
