Well I might be retrofitting a decent sized lathe that had the drive gears for the threading stripped out, don't ask me how. What we're looking at now is setting the lathe up for CNC and just ripping out the thread gears and feed gears. This isn't a problem really if you're not doing much with the machine. My main question is how to set the retrofitted machine up to be able to do threads. There has to be somekind of encoder on the chuck/spindle to tell the computer where it is and the computer then has to be able to tell the servo for the carrage drive where to be. My best guess is there is an encoder attached to the spindle and that would connect into an input of some sort on the breakout board. Any help would be greatly appreciated.
