CNC controller enclosure

I converted my Proxxon MF70 mill to CNC quite a while ago. When I was testing things out I wired up the PSU and controller board and just threw them in a Tupperware container so that nobody got electrocuted. It even had the lid open to allow the cables (including 240V mains supply) in. A temporary hack if ever there was one. You know how temporary hacks are though – they tend to stick around longer than intended.

Well, I finally got round to making a proper acrylic enclosure. I attempted to mill one ages ago, but struggled with the small working area on the MF70 and abandoned it. This one is laser cut. It’s held together with machine screw’s and has two shelves – one for the PSU and one for the TB6560 based stepper controller. I particularly like the rounded piece for the power LED and the hexagonal grid for venting.

I’d be happy to share the design files if anyone is interested, but I doubt anyone has exactly the same setup as me. I also altered things as I went, so I don’t have any “final” versions.
