R&D prototype stage with the electronics of this. The driver design has changed slightly to take advantage of more power to enable a wider variety of stepper motors. The electronics will now be based on the L297 and L6203 combo and will drive bi-polar stepping motors up to a whopping 4 amps per phase. The driver circuit will be designed to drive three axes without the need for a breakout board. That is to say, you will only need one driver board that the parallel port will connect and output to the three motors. Very simple.
The kit will be offered in two forms. the first configuration will be a kit that will require complete assembly (approximately 4 – 5 hours assembly). The second option will offer the electronics assembled.
Stay tuned during this timeframe that I will be developing this kit and I would like to hear any comments that you may have. If there is a specific product or component that you would like to see, or see develop, please provide feedback.
