New start

Wouldn't have the VFD so close to the drives. I'd move all the Power in to same location as VFD and separate the BOB/Controller/Drives far away as possible.
Not fan of PC in the case because it's creating heat which kills drives etc but if you must then you really need think seriously about heat extraction.

To be honest unless you have exact dimensions then sketch like this never gives true picture so your better getting all the components together and lay them out on table and you'll quickly see best layout. Often it's little details like wire routing etc that lead you to best layout, you also soon see that you don't much space as you think you've got.!!

Cheers Jazz!
I have exact dimensions and have laid all the parts out. Can't take a pic right now because of sick kids. Wife will kill me if I make a venture to the shed :D
The box is 100x50x20cm.. It seemed roomy even with trunking and din rail and everything :)

I would get all your bits together first and then lay them out, you will be surprised at the amount of space you need.
Pic of one of my control boxes. This one power the lathe and mill with mpg's etc

Haha !
Clive it looks like you might have one cable to many in there!! Just kidding :)
How big are those? 60x60?

No 50x50x20. I got carried away it was just for the mill at first then I added another two drives for the lathe etc etc. the pc is on the door with the monitor on the other side.

Just for the thought..

If I were to mount the vfd outside of the cab..
Separate mains connection with emi filter and still cy for the spindle..
How and what should I route between vfd and Bob? Cy? What I'm planning on using is software controlled start/stop and speed. So I'm guessing 4 core should do it?

Well.. I'm impressed!
I would be seriously out of my depth shifting through all that. But I guess it's easier when adding one thing at a time with purpose in mind!

Help :D

How about this layout?

I take it they are AM882h's not just standard AM882 which are DC only.

3 of mine are AM882h's and one AM882 so I had to go the DC route.
