That BoB does not appear to have the 0-10v output needed to control speed. So the answer is probably - buy a different BoB.

The BoB the OP shows doesn't do that job, in fact they are crap.
The one Cropwell has linked to does the job far better, used loads of these and if you shop around you can get them as cheap as this.

Depends on what spindle motor you have.
If it's the high speed water cooled Chinese ones then it's to the VFD. If it's something like a Kress then you need a variable speed power supplyJohn S -

I have got one sitting in a drawer, one day I might be arsed to fit it. Trouble is you have to hack out the original onboard speed control which means you have then dedicated it to the SuperPID, and I aint got time fer that malarky !

I have a air cooled spindle with a vfd so I connect to it then. I will have a look today at the vfd and see if it is self explanatory as to where the wires go thanks for the help so far
