I have the China TB6560 controller, For the power in put it says 12-36 V. Is this REALLY 12-36? If so I should not have a problem with 24v, right? or does it depend on how big and power demenading your steppers are?
A lot of people use 24-volt power supplies with TB6560 boards. That's the voltage that I'm planning to use with mine.
I'm not sure that I would go too close to 36 volts, though, even though the boards claim that they can support it (and the TB6560 IC's maximum rated voltage is something like 40 volts). Too many people have had their boards go up in smoke, so it's a good idea to give the upper voltage limit some breathing room.
