oh is your dsp a richnc model.
Alan, I don't know, there's no labels. They also told me the software was Ucancam, which it's not. It is ArtEngrave10. Some of the icons are in Chinese and the help is in Italian. I don't know if the salesperson is dumber than a rock, or they don't know their product.
I had a problem similar to yours when I first got my CNC router, and it turned out I was saving it to the wrong post processor. Once I corrected that, everything worked fine.
