Most users do not require this feature. Don’t confuse True interpolated 5+ axis motion with simply having 5 or more drive ports on the CNC control board that all can command and move 5 or more axes. Allin1DC, Hickory, and Oak without this 6 axis simultaneous software is considered a 4+2 system. Which is: Fully interpolated motion for ANY four axis in ANY combination at ANY given time. For instance XYZW, XWAB, ABCW, ZWAB, XYAB, ZYAB, etc..
