Hi everyone. I am so close to finishing my lathe thanks to a lot of help from here. One last thing is controlling my lathe motor and VFD. It can use modbus and also analogue. Can someone tell me how to do this and what pin do i use on the BOB. Also, must I use stepconfig?? I have been reading for about 2 hours now and got nowhere. Thanks

Morning Andy. Sorry, ignore my post. I looked for days trying to find where to connect the board to the VFD but have found a more in depth manual and my BOB does not have a pin for 10V control. Only a relay to turn motor on or off. So I have ordered a new BOB from E-Bay that does have a dedicated 10V pin.
