Right, I have bought a EMCO Compact 5 Mk1. I want to convert it to run Mach3 or similar program.

What I would like to know is where to start?

Do I need homing sensors on the axis?
Where about on a control board would I wire in the rotary encoder off the spindle.

If anyone has any experience on doing thing advice would be much appreacted.

That is the main board I was looking at

Cheers,

Pete
