Free PDF plans for cnc plasma cutting table water table build and easy free woodworking projects. My experience is that everyone and their cousin has a consumer grade plasma system in their garage, nobody wants low def plasma cut parts, high def plasma is troublesome, laser technology is growing by leaps and bounds, plasma technology has dead ended, waterjet is good for everything that laser and plasma cannot do and CNC turret punching is absolute king for parts that are a mix of cutting and forming.
Yeah, I have to stand over my machine and adjust the torch height manually and that means I can’t do anything beside cutting when it is acting up. I finally found that 14 Ga doesn’t react wuite so strongly to the Plasma stream heat and allows me to make less adjustments to the torch height during a long cut series, I try to cut up a whole 4X8 sheet when I push the start buttib.
These modules provide access to step and direction pins, optically isolated digital input and outputs and a plasma machine interface, which are all accessible through Mach3 using the custom screen sets supplied by CandCNC. The table can find the height of the plate or sheet at various intervals and account for sheet warpage etc… and still maintain optimum torch height for best cut quality. Consider that it may be a good idea to go all the way through getting a simpler machine working before graduating to your ultimate CNC project.
The table will probably be 75x75x5 square tube and 50x50x5 square tube with a water tray similar to this. The table was fully developed in a 3d modelling environment first and then built in my garage with average tools to prove the design and assembly was feasible.

The components that make up this axis are precision Hiwin linear profile rails and precision grade MOD 1.5 racks on each side of the cutting table. If the plate is cutting under 1-inch water, the metal contains most of the smoke and dust so that there is no need to use any dust collector. The water table can absorb up to 95 percent smoke and dust which are generated by the cutter during operation.
The basic plasma cutting process involves creating an electrical channel of superheated, electrically ionized gas i.e. plasma from the plasma cutter itself, through the work piece to be cut, thus forming a completed electric circuit back to the plasma cutter via a grounding clamp. And, while I dont know this for sure, you basically need to cut a deal with the city because you put so much water down the drain to run one. Depending on how many corners you cut with the CNC Router, and how elaborate your CNC Mill project is, a CNC Mill is probably the most expensive, hardest to do, but most flexible DIY CNC Machine.
It is reduced to 3% of the water volume in the water table and, according to the MSDS sheets supplied by the manufacturer, it is legal for disposal in any public drain or even on the ground. Now you need to add a CNC plasma table or two to the shop so that the torches can be used more effectively, but this is a much bigger expense and you are not sure where to purchase the tables. The water above the air chamber is usually 6” deep when raised to the bottom of the material.
I had major difficulties deciding what type of machine to base mine on, what mechanics I should incorporate, how big to make it and so on… In the end it all came down to time and money. I had the gantry drawing from Precision Plasma which has a width and length you have to build to, and also take into consideration the gantry tube distance to the cutting table height.
