Hey thats awesome... I just looked it up and it is actually very similar to my machine. I just bought a used HH Roberts Standard Modern 14x40 CNC lathe. Did your machine come with stepper motors? Mine came with DC brushless servos and resolvers but I am thinking I will swap motors and drivers to brand new stuff here instead of screwing with the old stuff. What HP is your spindle motor I need one of those too. Nice to meetcha! Peace
