I watched the previous owner run the machine flawlessly....I get it home, get it set up, do some air cutting with simple text. All worked fine. Next day I try to run the same simple text test and the cuts are all concentrated to a 1/2" area. I've loaded other codes into it, like a simple square. Same results, all of the results in a small area. The axis all jog fine with the keyboard. I have no idea what is causing this, but I have a hunch its me....HELP!
