The Quad design intends to address three areas of concern. Instead of three columns, Quad uses four columns allowing effector tilting, which one day might be useful for milling but should certainly address the problem of hotend tip alignment and dragging that is worse when, say *four* hotends are in one effector; allowing a square, not round hotbed, which admits of laminated Peltier chip design, consequently if a range which is cold enough obtains, through differential thermal expansion, allowing part auto release without scraping; Quad also incorporates a new spider rod joint design also intended to have no backlash and it may be possible through some optimization of dimensioning and clearances to allowing milling such as of the hot cold bed cold side air channels.
The way I'd build it would be hollow rectangular tubing with sliding blocks inside on leadscrews:
Each block would capture two plates on opposite sides spaced rightly.
Each pair of plates would capture one ball strut end.
The effector would likewise capture ball strut ends. Sophisticated sockets wouldn't be needed.
