Hi, I have a lathe which I'm converting to CNC using a TB6560 board.
It has an output for spindle control but no way to connect a speed sensor to it.
At present I have a 240v single phase motor on it ( I hope to convert to 3PH at a later date) and I would like to connect a speed sensor to it so that the thread wizard will know how fast it's turning.
I could hook up a separate display so I would know the true speed, but I would prefer to use MACH3 to detect the speed directly if at all possible.
Does anyone know if it's possible to connect a sensor via another input such as USB?
I have asked the manufacturers but they reckon no-one has asked about this before and could offer no advice.
Thanks for any suggestions, except for "go buy a gecko"
