Great, just set this up this weekend coming from a Xpro v3 that was nothing but a pain from day one, this black box is much quieter and seems to be more reliable. The box its self is a really tidy package and has lovely removable screw terminals that are all labeled clearly.
I was origanally concerned about there being no conection for a external pause/resume buttons but i was able to get around this by wiring a momentary button to the door sensor connector, now when i press that button the machine pauses mid movement until i go back to the computer and click resume.
If you want to make stuff on your cnc instead of tinkering with the darn thing all the time i recomend this controller as so far i am very impressed with it.
message to ooznest please import the openbuilds interface board so i can buy it from you, please oh please!

Bought to replace a spark concepts v2 controller on my original ooznest machine. driving the black box with open builds cnc. easy to exchange controllers and calibrate movements.
very happy with the performance especially the reduced noise from the steppers and would certainly recommend this controller.

Transformed my CNC router! My old MACH3 driven controller was driving me mad just for the amount of time and effort keeping the old PC needed to run it working. The BlackBox is such a massive improvement along with the FREE controller software. I now have 3 axis limit switches working to allow a homing function. The speed and spec of the PC have no bearing on how the router performs. The unit is so compact it’s easy to intergrate with my old machine without wires dangling everywhere. As a bonus, I didn’t realise it comes as a kit. I had much added pleasure assembling the thing.

My cnc controller of choice. i have two now. easily configured, lasers, spindles etc more or less ‘plug and play’ the built in wizards are a real boon!
