Video Description:
Building a CNC plasma cutter at home is as awesome as it sounds, albeit a little dangerous. Plasma can reach temperatures greater than 25,000C, and no metal in the path of this inferno stands a chance. In this build, Dr. D-Flo will show you how to control the motion of the plasma torch through linear actuators to achieve automated and precise cuts. This video will cover topics such as the operating principle of plasma cutters (high frequency versus low frequency plasma cutters), specialized components required for CNC plasma cutting like the floating head and water table, how to generate tool paths for plasma cutting, and many other topics.

This DIY plasma cutter (known as the LEAD plasma) is based off the OpenBuild’s LEAD Machine 1010 (Paid Link: https://geni.us/Lead-CNC). Dr. D-Flo received a BETA version of the lead plasma kit for review. Due to receiving the kit for free, this video is contains paid promotion, but Dr. D-Flo has used parts from OpenBuilds for several years now.
