This appears to be what is happening when I turn the machine on.
Replied by tjamscad on topic LinuxCNC error on Enshu VMC530
This will allow LinuxCNC to load but when the machine is powered on the drives and contactors go crazy. The also causes a joint 2 following error. That is my Z axis.

If you have schematics, you should really check for voltage drop on the 24V rail, and the mains power drop.
Also check for anything shorted on the 24V side. Start disconnecting things and testing, one by one.
That is a no god state as that switching on and off will mess up something else.

In your video one of the contactors is sparking a lot, so check what it is connected to or disconnect the output wires from it.
That might be the actual problem, but it also might not be, the sparking can be caused by an iductive load also.

If i comment out the XX axis PRDY line for X,Y and Z linuxCNC will boot and run I just can't move any axes.

The relay that is sparking so much in the video is for the hydraulic pump.

Unfortunately, you are using non-standard board addresses, so the diagnostic program won't work properly.
The diagnostic is dumb, it will only test an encoder board at address 0, a DAC board at address 4 and a DIO board at address 6. So, if you change one of your encoder boards at a time to address 0, then you can test it with the commtest mode. Then, you can swap the address settings and try the other board.
If the commtest works OK, that will indicate that communication between the PC and the encoder boards is good.
If the commtest does not give a no errors report, then you have to debug further.
