Certainly seems like something to look into, but I cant see how the LightBurn software could have any idea how my laser performs and so shouldn’t be able to show an offset in the preview?? Surely LightBurn would create the g-code aligned, show it aligned in the preview and then depending on how the machine performs you should adjust the offset (assumingly using trial and error before getting it right).
Attached is a better example of what is seen in the preview window.
