My CNC controls are in an old computer case but with the Arduino + terminal block, 4 drives, 3 PS (48v, 12v and 5v) this is pretty packed up and the wiring looks more like a spaghetti bowl than a CNC control box.
I have to add a 24v PS, DIN mounted terminal blocks and relays but for this I need another case.
I've looked at real control enclosures made of metal but it is out of my price range.
I know that it's not ideal, but I'm thinking of making a case made of wood.
