Does this wiring layout look ok for a starting point?

lots of drivers is this double traction on x and y

Of course the door closes. Did I add too much? One of the major items on the door is the hardwired wireless 433 Mhz pendant which I would be lost without. One of my mates suggested to have seperate LED indicators on each power supply 5v, 24v , 48v and that has been handy troubleshooting when building it.

Yes the 7i76e supports 5 axes so I added the 5th driver for a future rotary axis because I had the driver available but I probably will never add it. But I did test the functionality.

You seem to have a lot of power supplies. I suppose you have them now, so might as well use them. but my milling machine has one 24V supply (ironically to rotary axis that I have since sold...) and then the 12V, 5V and 4V (for some Ikea LED lights) is all derived from the 24V by some little buck converters. These have LED voltage readouts, which is handy for troubleshooting.

I'm happy to drop the number of power supplies if that will help. I could use power bucks for the 5v as this only powers the MESA and the other one only powers the home switches. Would this be a better option?

3flat powersups in a row is not that good mount this brings in EMI for shure

and the twisted powerlines are a hell of a magnet on DC

As in the above would it be better to use power bucks?
Should I untwist the power lines? I've bought some copper tape and was going to shield them by warapping it around the twisted pairs and grounding to the ground plane?

One random example from Amazon UK, but they are on eBay, Banggood, Aliexpress etc too.

What's the benefit of DIN rails, is this needed or just the best way to do it?

Cheers for all the help so far guys.

Should I ditch 2 power supplies and go with power bucks?

I made the same mistake you did with power supplies that are far too big (And in fact the 5 volt power supply is unecessary) BUt heck what you have will work!

Thanks Rod
The photo's have helped ease my mind a lot. I read the Linux CNC best wiring practices and was basically shitting myself that I had one big antenna! Looking at yours which (I assume) works well I see a lot of my fears were unfounded. I'll crack on with it and update when it's finished.
