Andy, Gene - I do have a spare 12v linear regulated supply and a nice small
5v switching sitting by my new mill, was going to prototype with the 5v
first. (KBIC says 0-7v input in voltage follower mode - 0-5v will get me
going)
Interesting about the dc-dc converters; on reading, as Gene says,

I have a G0704 mill (known up here as a King Canada KC20-VS) that is
being CNC'd, with only one real issue cropping up.
The spindle speed control - original is a 4.7k pot, the spindle circuit
board is a copy of a KBIC 120 style board.
With the 4.7K pot in place, I measure 4.14v across the outer

Hi Peter;
Thanks for the response - I'll try that tomorrow.
My first mill (different manufacturer) was an easy replacement - no
external power required - so my mind was set in just do it the same mode.
So far, Chris Morley's pncconf is working well with your products - having
fun with this
