Tony, I completely understand about not wanting to be dragged down the rabbit hole of endless support for your lathe "conversion". You have shared a great idea, shared the electronics, and demonstrated the actual lathe build. Your gift to us is all that is needed for the "ee"-talented among us to arrive at a similar system. However, there are many of us whose neurons are running about 1/2 a watt when it comes to electronics! Have you considered, or been approached, by others that could take your design and produce boards and software support for a small royality?

James (Clough42) developed an ELS based on an Tektronics board that has become quite popular. I have often wondered why he stopped at just a single axis. Although, its clear his motivation was getting rid of the miserable change gears. I think he is now batching his boards a few hundred at a time. Have you talked to him? While a ball screw conversion and other physical features of a machine are as diversified as the world and bring the associated problems, I suspect your electronic system, or its logic, is fairly adaptable. I don't need or want full CNC, I just need an ETA (Electronic Taper Attachment or ball turner). LOL
