There is a small controller you built yourself that drives a stepper motor via a keypad with a small screen so the user does not have to input G-code or use a computer, all it takes is a key press that would work on this saw project for you.
You can set up a program with it to do division so a certain amount of turns of the stepper lifts the saw blade to a given height and same in reverse to lower, this you would need to workout yourself.
