Again, I really appreciate all the great discussion on this thread.
That's great it's working for you, apart from the known issues with these boards, what a lot of people also find using the various iterations of these boards, is that once the spindle is powered on, the noise that's fed back into the circuit renders the system unusable. Given it appears to be working for you now, if your not planning on using it with a spindle, you may well be exempt from the troubles!

It's rumoured that everytime someone buys a TB6560 based board, an engineer cries!
