The easiest control box of all my automated tools and I have five tools that use other than a Blackbox. This one really is easy to adapt to one of my other tools that had the control box get fried during a lightning storm.

Great Piece had motors turning in ten minutes

Very well-designed and manufactured. Robust (with a capital R). Requires assembly, but the online video and instructions are excellent. No problem to assemble. Once I determined my non-standard stepper motor wiring, it worked great. Mounted on my C-Beam with the included hardware. A significant improvement over my previous rinky-dink controller.

So far so good. Assembly was a breeze. Compared to my old system, it was like a laptop to a mainframe; fits in your pocket. Documentation is abundant and clear, support is cheerful.

I was surprised when it arrived with my C-Beam machine. It was packaged inside plastic bags but was well cushioned for transport. I found it hard to believe it came in parts and I had to put it together. But, after watching the Openbuilds supplied video I had no problem at all. It goes together really easy, program is just as easy to install and all the plugs needed are supplied. It really looks good in black. I would suggest buying a small jewelers screwdriver. The wires connect with very small screws, only 3/32nds wide. A 3mm wide jewelers straight slot screwdriver is almost to wide to fit into the holes where the screws are located. I had a 1/8th tip for my nut driver that was almost to big. I recommend this for your next CNC or 3D printer.
