Hi Andy

Thanks for the reply, currently slowly building around study and work, and as yet I have no spindle. Gathering info so I can get the correct type
That is the correct unit and on page 27 it gives the settings for the 3 codes and you can choose the output pin in the software
M3 set to pin 1 (me presuming A) and the other 2 unset but the option of Pins 1 to 7, wondering where those pins are and presumably the speed would go to the PWM of any controller but which is the speed pin.

cheers Dave
