Gregg You will forever regret building a plasma machine without a proper Z axis and Torch Height Control (THC). That was the action of the torch touching and then retreat to cut that you saw. Without the Z axis you will cut some hobby stuff, maybe. To do a proper job of it, the Z axis and THC is needed. I service cnc machines that other folk have build for themsleves as part of my business and I get to see all kind of problems related to plasma machines. I also build my own machines for customers and for all the trouble that comes with a plasma machine, I would not do without the Z and THC. There are many other factors as well when it comes to making a good cut. Search a bit on "constant velocity" and plasma's. You will be surprised to see the amount of effort that is required do do a proper cut. Also the Z axis and THC does not cost that much more. Finally, in my opinion, a plasma without a Z axis is like a fishing without a hook. It can be done, but it take much more effort.
