THC

Hello everyone,

I wonder if mesa-thcad 10 is enough for controlling the torch height for Smooth cutting. Or what are the best electronics and hardware for professional smooth cutting. For instance is ohmic sensing necessary etc ?

The Mesa cards can be used to build a great CNC plasma cutting table using LinuxCNC. I use a 7i76E with the THCad card. A lower cost option is to use the 7I96 card. Look at rodw's spaceship here:

The THCAD-10, a Mesa 7i76e and the new plasmac config described in the thread called "Another Plasma Component" is the way to go. You will be hard pressed to find a better plasma controller anywhere.

Thats what John, myself and few others are using. Phill has been working hard to make it as simple as possible to install.

Here is a video from JtKnives posted today using it to cut steel on quite a slope.


There is another one on my spaceship build thread I posted recently.

As far as ohmic sensing goes, if you are cutting heavier material, could get away with a float switch but I struggled with 2mm until I added ohmic sensing due to material flex.
