DIY Rotary Table Controller.
What is it?
It's a device which allows you to control a rotary table or dividing head.
It provides a simple to use menu in which you can enter values allowing you to divide circles into 'n' parts, move by 'n' degrees, rotate work continuously or even enter simply programs for production work.
For ease of setting up it allows the table to be jogged into position using 'jog' mode.
Construction is simple, it can be built on stripboard or a pcb can be constructed using the provided design. It requires a PIC microcontroller to be programmed using the provided HEX file (or I can provide pre-programmed chips at a small cost). Other parts are easily and widely available and are non-critical.
Typically the cost of the controller electronics should be around £20-£30. Additionally you'll require a suitable case, PSU (old laptop PSU is ideal), keypad and stepper motor and stepper driver along with a suitable coupling to hook up to your rotary table. (For most 4 to 8 inch tables the common Nema 23 motors are fine).
