I think it makes a nice project for guys like myself who likes to tinker. I can probably dovetail this one to the DRO driven project I started a year ago.
Not really sure on the jig rigidity though. Maybe triggered pneumatic clamping and release and triggered carriage forward and reverse with simple relay logic toggling the VFD. The way my VFDs are wired I can go from forward to reverse without activating the stop botton. Just thinking out loud.
Thanks, Boyd.
