guys, its been awhile but im getting back on track with this project... its taken a couple of turns however, current config is centroid acorn and DMM 1.3Kw servos... just waiting for the backboard for the electronics to be cut... i tossed the original cabinets in favor for a later model cabinet ( single cabinet to hang off the side of the machine )

would love to get some input on motor speed control... keep the original pneumatic s ? switch out to vfd ? anyone with ideas on spindle speed tach ?

here is my latest video on the build.. showing the electronics and servo selection
