I am new to Mach and Sheetcam. My plasma table with dthc goes down to touch the material then raises and the it raises another inch or so as it moves around the drawing.
I have removed the torch and replaced with a piece of wood to avoid damage to torch until I get it dialed in. Here is a link to the video. There is no spam in my video http://www.youtube.com/watch?v=1yg61M8qo60

I am sorry I forgot to ask the question. Do you know what I need to change so the torch will remain approx. 250 above the material?

you need to edit your z for now but make sure your program value for z has a negitive. just a thought. maybe post your code here to see the problem.

Tjstamp, thank you for the information.. got it working
