About RelayRepRap

This project is about exploring whether it is possible to make a RepRap control system that can be made by a RepRap.

A counter and clock divider circuit

This video shows a counter circuit that I hope will form the basis of a simple punched tape driven system for controlling the speed and direction of a pair of stepper motors.

The punched tape will have a simple mask for each motor for selecting the speed (1/1, 1/2, 1/3 or 1/4 of the clock rate) and direction. A third mask will be used for specifying the count of the modulo 12 counter on which the punched tape should advance to the next position.
