    I must admit that this unit exceeds all expectations. Easy to use 4 Axis all competitions.
    Forget the complicated Mach3, ignore Acorn complication and and wiring mess that could take you days to setup. And openbuilds good controller yet BUILDBOTICS is more powerful 4 Axis and smoother operation. I am so satisfied and happy to buy it.


    If they sell this on Amazon or ebay or etsy they will be on top of all companies.

    God bless you

    Great Product

    I replaced a Blackbox on a Newcarve 1045 with this Buildbotics controller. It's very easy to set up and get going. The cuts seem so much less violent and smooth. Doug's support, when needed, is great. I have zero complaints about this controller. Top-notch.

    Great Service!

    Posted by Luke on Aug 24th 2021

    I’ve been running with an early model of this controller for years. Last fall, my discount power supply died and took out this controller with it. I was glad that their tech support took the time to help me debug the problem and took care of me when I had to send the controller back, for analysis and replacement. This is really a great product and its great to see that they stand behind their work. I definitely plan to support them in the future.

    Still working great after 2 years

    Posted by Ian Douglas on Jul 20th 2021

    I bought a 6040 from China and upgraded the controller with this one. Still works great after 2 years. Updates to the firmware have always worked without any issues. Highly recommended.

    Excellent Controller

    Posted by brandon kelley on Jul 6th 2021

    I purchased this for my Mega V XL CNC and I am so glad I did. I wanted a standalone controller so I wouldn't need a PC near. I love that I can create a file in the house and send it to this controller. Excellent controller and I highly recommend it.

    Great controller

    Posted by Bryan on May 31st 2021

    I built my CNC from scratch and as a computer programmer I thought I'd do the controller also, scrape together some parts and some freeware and have at it.... what a waste of my time. This controller is great, I was up and running in hours and have been doing projects ON the machine ever since. What a great turn key unit. I had a couple questions and the support was fantastic, timely and accurate, this experience has been all around wonderful.
    Thanks for making a terrific product,
