J tech laser on onefinity x50 journeyman shifting halfway through a burn

I’ve had a couple instances where my laser has decided to clunk and shift my image over a couple inches during a burn. I had it happen once and realized I was using the same layer number on lightburn for my image as I was for the square I used to define my project size. Even though the output was turned off on the square, it was causing problems. I defined them as different layers and that seemed to solve the problem. Now today that isn’t the case and it did it again. I did try opening a new internet tab on my laptop during the burn and it clunked and shifted almost immediately after opening the new tab. Could this be related? I thought once it was loaded on the cnc if would run independent of the laptop. Any insight would be appreciated!

Thanks,
