You could always use small interface relays for the pushbuttons. Energise the coils from the bob then wire the 'volt free' contacts across where each button connects.
Not sure how the pot is wired as I don't have a diagram for that board.
Re: Emco Unimat Pc control
Thanks, I thought the pot would be the hard part. Any info on these lathes is non existent, let alone a schematic.
I will see if i can trace the circuit. As far as I can tell the motor is under powered and the speed control dosnt offer full torque at low rpm so might not be worth bothering with but thought Id give it a try before getting a bigger motor and dedicated drive.
