Here is a project that I have been poking at for almost a couple years now. Designed with the commercial user or discriminating high end hobbyist in mind, it uses HIWIN precision ground ballscrews pushed by 1200 ozin 3 phase closed loop easy servos. .000016 step resolution and over 6K ozin torque at the gantry. Acceleration (to be tested) in the 1800-2000 ipm/sec range
24 by 36 cutting area with a 5 or 6 tool ATC. Air operated, slide away tool rack and a few other goodies to come in the future.
