I have found the BOB axis controls, they also feed into the 42 pin connector and am looking for the feeds from the board to the steppers (4 found and 2 to go)
That should be easy enough just follow wires to steppers. If there was a better picture of the original board i could probably tell you. There will be 4 wires per stepper. So look for blocks of 4wires that will probably be same colour wires.

The E-stop is easy enough and you have relays and contactors in there but first, you will need to find their voltages and what other things you need to control. I see what looks like a spindle Speed controller board so this will need to be incorporated into your wiring and safety etc.

To be honest, if you are going to start again with a new controller and drives then I suggest you trace wires and label them, then rip out everything else in the control box and start afresh. It's often quicker more reliable and less confusing.

If you inventory what you have and find the voltages etc and tell me what controller you are going to use I will happily help you work out a wiring schematic.
