This is my DIY CNC plasma cutter. It is 100% built from recycled parts. The total cost to build (with the exception of the plasma torch, is < $200. It is very much a work in progress. I am working to reduce backlash, and improve precision. I have only just recently attached the plasma torch, and just need to wire up a controller for turning the torch on/off. I am planning to use a waterless grill for V1. I am also looking at upgrading the linear rail system to one based on openrail, for more accuracy.
