Thanks for that Mitchejc,

For info here is where I got to using the SSR (small white square in the middle of the top DIN rail for those who don't use them):






But since these pictures were taken I've removed the SSR because as mentioned above I don't think it works well with the transformer. If it had worked then I didn't plan on using a heat sink because the 25A rating was just to help it survive the unrush current (which is momentarily 100s or 1000s of amps), but then it should settle to a couple of amps (?) for normal running. But if you've got a heat sink then I guess there is no harm in using it anyway.

New plan is to do what I should have done in the first place which is to run 24V DC control instead of 12V (as industry do) which means I can use a 24V DC contactor to switch the transformer and SMPS. The e-stop can then (through the relay) cut power to the drives in an emergency.
The proximity switches are happy on 24V and if I ever upgrade to something like the CS labs unit this also uses 24V. Just waiting for all the new bits to arrive from China.

At the moment I've laid the earth terminal blocks out to act as end stops/cover plates for the main grey terminals because in case you didn't know one end of each JXB4 terminal blocks is open so the last one in the row is 'exposed'. I've got some cover plates on order and when they arrive I can then cluster the earth terminals in the middle to make it as close to a star layout as possible.

Also when the new relays arrive I plan to re-do the diode layout and run it through a terminal block instead of hanging out the back piggy backed onto an cable.
