Thanks. Managed to get it work, but not with the board itself. The Pokeys U board is limited to 3.3V PWM max. Confirmed by their support guys and online via a thread. So got a £4.99 RS485 USB adaptor which I got working last night. So no need for spindle control from the Pokeys. Not ideal but it works.
