Ok, good to know thank you. Gantry is pretty light and feedrates aren't that high.

Capacitor mount brackets arrived today so roughly laid it out on the aluminium plate. Plate will be trimmed off just after caps, and before MCB.

I noticed that the toroid 2x24V AC cables are a much heavier gauge than the 240V AC cables so I'll match that heavy gauge with the DC cable out of the rectifier and over the caps.

It's a bit bigger than the blown SMPS it replaces but should still just about fit in the cabinet, top centre:
