    CNC Controller

    The Buildbotics CNC Controller is Amazing. I have a CNC with a controller built by another company and it is like comparing a cadillac to a chevy, both will get you there but there is a world of difference in the ride. I have thrown y old controller away. The buildbotics comes with local network wifi compatibility so you can control the controller from anywhere in the house. This is a huge advantage since no one wants to sit in a room with all the sawdust, noise and laser smoke. Most controllers lack PWM (Pulse Width Modulation) but the buildbotics comes with it standard. PWM allows you to modify your CNC to use a LED laser at its fullest capability to burn pictures that are accurate and true- on request I can send some pictures I have burned. The setup and controls are intuitive and well designed. You can tell a lot of thought went into its design, for instance, the control screen gives you both the time the machine will finish the cut/laser as well as a countdown until it is done- and it is totally accurate. It also has an onscreen mockup that will show the machine cutting/lasering the proposed project. It will tell you the percentage of completion and it comes with a game controller which makes moving the spindle/laser to the right spot a breeze. It also seems to control the motors in a much smoother fashion then my old controller. It comes with the optional add-on camera (which I recommend purchasing)so you can see precisely what is happening. If you use this for a laser it is comforting to know that the house isn't burning down. Technical support is also phenomenal. Doug will spend any length of time, at virtually anytime of the day to help solve any issues you might be experiencing. I recommend this unit without reservation. It is well worth the money and hard to appreciate until you actual use it.

    When I started to build my first DIY machine 3 months ago what I feared the most was the controller part. This plug and play controller can support large stepper motors, can control a VFD and have an user-friendly interface.

    I can only highly recommend this product and its customer service.
