I have been building a plasma cutter that runs on GRBL 1.1h and I was using a self designed controller.
This controller worked fine until I attached the plasma . A soon as I triggered the torch, everything shut down.
I now find that the BlackBox is available again, and wish I was able to get one before I built my own system which actually cost more in parts than the BlackBox itself.
Now that they are available again I want to order one and get my machine running as it should.
Plasma CNC machine
The plasma CNC that I have built has a water table that measures 1350mm x 650mm. The water is flooded onto the cut area while cutting and recycled around with a pump. This is to reduce smoke, cool the metal being cut to reduce distortion and also to keep sparks to a minimum. Most of the machine has been made from aluminium , the frame and table from steel, the water table, stainless steel.

Reason for this BuildI have several CNC machines that I have designed and built over the years, but often I needed a special part to help with building some project and the need for a CNC plasma became apparent .
I started to research what would be the best solution for me and decided that after seeing so many different designs that I would be best to design my own from scratch.
The mechanics of the design are straight forward and based on common solutions, the electronics I thought would be simple also due to building other machines successfully, but plasma is a different animal, it needs some special attention due to the EMI problems associated with plasma systems.
The BlackBox may be the answer to this problem and I will incorporate one into this design. If as successful as I hope it will be I will be building more similar machines for several friends that have shown interest in my project. Already I have ideas of an improved version of the hardware that goes into the machine design.
