I am going to remove everything and start from scratch.
Run Acorn and CNC12 running on the PC for several hours. Make sure you have no errors.
I would then pull the drives out of the cabinet. On a table wire them to Acorn one drive and motor at a time. Get that axis to move. Check the error logs as you go. If OK add the rest of the drives and connect to the motors. Run the machine with parts on the bench to test and watch for errors.
You do not need limit switches. Use simple home at first
Then wire in your spindle drive/motor (leave the axis drives and spindle motor on the machine.
Point is, take it one step at a time until you see the errors show up. Then you'll know what your problem is.
THEN on the bench, wire the back panel and retest everything before putting into the cabinet. No errors, put it in the cabinet.
Remember all grounds to ONE point, where the ground of your power cable comes in and lands.
Use shielded cable from Acorn to your drives. Ground one end of the drain wire. I would take it back to the one ground point.
Here is an Acorn System Schematic you can look at for some ideas, or to wire it up as the schematic shows.
