This seems like a pretty nice xy table, I think it came from an industrial sewing machine. The threads don't seem to be ACME, any guesses?
It has about 10.5x10.5 of motion. I think the motors (not shown) are 450 oz unipolar steppers.
I'm considering mounting it to replace the Y and Z axis on top of a Solsylva table with the the goal of routing dimensional lumber or making small parts out of plywood/mdf.
My motivation is purely for hobby purposes. Suggestions welcome.
