I built an electronic leadscrew for my old metal lathe (since sold). This is an in-progress picture of the enclosure for the electronics. I have yet to move it to my new lathe, since it has a gear head and it's pretty easy to change thread pitches.
Earlier, the control box with its display and buttons, on the bench.
And a bench test of the display board, wired up to a dev board, a power supply and a logic analyzer.
A couple more test clips: one at the bench with the control box, and one on the lathe itself.
