    Fun assembly project

    Posted by kizmit99 on Dec 10th 2019

    I haven't actually used the BlackBox to drive anything yet, but I got it to drive a CNC mill I'm planning to build in the next few months. This basically comes as a kit, but the assembly process itself was quite a bit of fun. It seems well made, and I'm certainly hopeful that it performs as I'm expecting it to.

    BlackBox Motion Control System

    Posted by Mark in West Texas on Dec 7th 2019

    The Blackbox replaced a TinyG controller running with Chilipepr which needs internet connectivity. One of my shops is located in the sticks without internet and this seemed like an affordable option. I grabbed the Blackbox on sale. It went together without a hitch and fired right up. The only headache I ran into was trying to mount it in a small terminal box. It would be nice if the mounting holes were located on the sides instead of the ends, but no big deal. Thanks for an affordable all in one unit that works.

    Although I’ve not tried controlling anything with this yet, I’m looking forward to it.
    Simple connections for components, I just gotta build myself a cnc now.

    BlackBox Rocks!!!

    Posted by Nicholas Herbert on Dec 2nd 2019

    This is the easiest solution to hobby CNC. Setup was about an hour with OB Control software. I set up a XYZ touch probe and it worked perfectly right after setting it up. I don’t know what else to say but do yourself a favor and buy the BlackBox!
