Complete Newbee - Need help

    Good morning, I am new to this community and joined in hopes you could help me step into the world of CNC’ing. Couple of years back I purchased this multi-cam CNC that had been sitting for a while. It had been used to machine deep pockets into Ovation guitar bodies. After cleaning out all the fiber material I found all the slide bearings in almost new condition. I took a bunch of picts and proceeded to completely disassemble the unit for restore. All the wiring too! I thought I would I’ll just look up what information I need to put it back together… bad plan! Not only can I not find how to wire these components I’m not even sure where to begin, what to keep and what to ditch.I will replace the spindle but would like to keep using the x,y,z motors. These are Allen-Bradley N-3412 B series brushless servo motors powered by Electro-Craft DDM-009 drives. All the rest I want to have new. I figure to use LinuxCNC on a Raspberry 5 with Unbuntu to control these x,y,z axis and (maybe) control the spindle (whatever that will be) separately. What add-on board and how to finally connect the motors escapes me.I have looked and looked but don’t know where to start. I need help.I would greatly appreciate any advise or direction. 

The way I would approach this (many ways).

First you need to look at the old controller and pray you see a step and direction text somewhere on the board, wire labels, anywhere.

If so follow the below. If not I'd probably see if I could find the software or manual to program the drives. Maybe chapgtp can help here?

If it's step and direction your life is easy
Step 1. Buy a 7i96 or 7i96s, if doing spindle speed control with a vfd S makes it a bit easier. (If you want to check sanity buy a stepper and drive to verify it works before testing the drives)
Step 2. Test the existing servo/stepper drives to see if they work. If you tore apart the wiring this may take some trial and error.
Step 3. Figure out the screw pitch and run through the pnf config

Finally that spindle looks usable...prob the easiest thing to save. Is it a 3 phase induction motor?
