Hi All,
I am considering cutting some gears and therefore I need a rotary table or dividing head. I am considering building a CNC dividing head.
The basic idea is to build a dividing head like Harold Hall's basic one and then power it with a stepper motor to get the divisions.
So here are my questions: first, what exactly do you need for precise motion control? Will a stepper motor, motor controller, and breakout board be enough for this sort of precision? I will have it geared down (to the motor). Software shouldn't be an issue, I should be able to sort that side out.
It would seem that I could build something like this very cheaply - that is the chief attraction of this idea. (+ I should be able to cut gears with any number of teeth)
