Can anyone identify this control board and help use it

[SimonMaltby]

I brought a fairly inexpensive 6040 from Ebay - Germany (China seller) and although happy with the basic machine I have been trying to get PWM spindle control and direction to work. I also want to add some limit switches. The trouble is i'm really struggling to work out if I can connect to this board and if so what port / pins to use in Mach3

I managed to get one relay to fire using Port 1 pin 7 just through trial and error, but cannot get any change in voltage through the pin labelled 0-10v it's just stuck at 9.9v.

Can anyone identify this board or have you used one previously? I would like to keep using it if I can as it seems to have all needed. So just before I look at changing the control board and adding Motor controllers I thought I would ask around and see if anyone knows the board.




Many thanks and happy Christmas to all.
