I'm back to converting my Boxford TCL160 after quite a long break.
The Spindle and X and Z axis are now all working.
I now need to hook up the original encoder to give me the speed of the Spindle.
The disc on the end of the spindle shaft has 100 holes and on the outer rim there is one hole.
There is a dual slotted opto used to sense the speed. is has 4 wires, yellow,red,blue,green,
I need to hook these into my breakout board which is a CM106
