I was just thinking about creating a small tabletop CNC machine and was drawing a simple picture of the table when I began to think that the linear rails were redundant if I were to replace them with 1” Acme screws. I’d either drive the two screws using a timing belt or two servos. I’d use two AB nuts in place of the bearing blocks. Does anyone know how rigid 1” Acme screws are over a 24” distance? Also, what issues/problems to look out for?
