Laser engraving patterns sometimes move forward and sometimes move backward

So I’ll start an engraving and the first couple inches goes where I planned then it jogs over several inches to the right, engraves a couple more inches, then jogs back over in line with the bottom. Not sure if a lightburn issue or not but haven’t been having the problem until now.
