Half of Image burns on Rotary Chuck Why?

I am using a Boss LS 1630, with lighburn. Pulse for the chuck is 10,000. did a test with a mark on the object with Diameter. All lines up perfect. I created a 1.5" circle With a letter T. The LS only burns half the image perfectly then returns to origin. On the little LCD on the machine shows solid black on half the image that bured and a faint blue pinkish line on the other half the image that didn’t burn. What is the issue?
