Hello everyone,
I want to order a control enclosure and I have a 800 x 600 x 300 mm size in mind for my 3 to maybe 4 axis (in the future) router. My question is will this be large enough and what sort of size enclosure do others use that have similar machines requiring similar electronics.
Regards Chris
600x600x200 0r 250 should be more than enoughQuote:

Best option is to find sizes of all the key parts you'd like to use, then do a quick mock-up.
My tip would be to leave plenty room around components to run some cable trunking.
I used the largest old PC case I had lying around in the shed. But then I'm an incorrigible cheapskate!
I use 500 x 600 x 200. There are 5 x DM860's and a VFD plus the other stuff :)
All good suggestions, I've just thrown one control box out that was home-made/formed from sheet steel - to the limits of my bender (90mm). That was not deep enough when I replaced my baby drivers with slightly larger drivers (TB6600s?, can't remember and not close enough to check) I wouldn't recommend any cabinet less that 200mm depth.
I'd go along with the "it's never big enough" idea. Do a dummy layout of the bits going in there, work out what you need to house them, then go a size or two bigger. Otherwise, wiring the thing is going to be like keyhole surgery. Cable trunking as mentioned above is useful but takes more space (and I wouldn't wire another control cabinet without it) and I used a fair bit of DIN rail for mounting things along with a lot of DIN rail terminals. Also consider using crimp-on cable terminations - the little ferrule things - which are cheap enough from China and make wiring much easier and reliable with less chance of odd stray strands causing shorts.
Thanks guys, think I'm going with this one.

Will I need some sort of backplate to mount the DIN rail onto?
Looks to me as if there is a backplate as part of the package - the "2mm galvanised steel mounting panel" item. Does make it easier to get everything fixed before bolting into the cabinet.
Have you sorted out what you are going to do about external connectors for motors, limit switches, etc? Best if you can drill for those before getting swarf in all the electrics! Guess how I know...
Good point Neale. I followed an excellent build log you tube instalment that shows how tough the steel is to to core drill into. I will try to plan it all out beforehand.
