Hi,
Any advice would be greatly appreciated. I have just purchased a little cnc router for PCB work.
I have been trying different layout options while I wait for cables and connectors to turn up
There are three options that I can see and wondered if there are any issues with these, like electrical interference, heat concerns/ventilation or anything I may have missed.
Options 1 and 3 involved mounting the BOB onto acrylic and attaching this to the door panel.
The external case dimensions are 400mm x 300mm x 150mm but the removable steal base panel is 350 x 250 which is what I want to keep all the electrics on for ease of removal. All the connetors wil be mounted on the access panel on the side
Option 1 - and preferred option for me
Option 2
Option 3

My preference would be to have all parts in the case and not mounted to the door - Is there enough room to mount the powers supply on its side? Might give more room/options?

This document makes an interesting read if you want to focus on handling electrical noise in a system (thanks EddyCurrent!)

Hi Jim,
Thanks for the quick reply.
I did look at mounting the power supply veritally but the lock on the door hits the top of the PSU on one side and on the other there is a bar which sticks proud of the door panel visible in the second picture next to the gounding wire, which also hits the top of the PSU meaning I have to move the PSU more to the centre of the case.
Besides, being lazy I wanted it flat so I can easily access the screw terinals
Cheers

Thanks Jim,
I just remeasured and the lip on the door clears the PSU by 1mm.
Looks like your suggestion is the better one and it does give me a lot more space. I origanlly wanted to keep the PSU flat for ease of access to the screw terminal but I can live with it this way, how many times should I need to access these anyway, famous last words.
Cheers
Dave.
