It is no congruent de scremm whit the work

Hello, I’m using the 1.6 with mac and the lightburn s9, it was working very well, suddenly a few days ago something changed and the images that measure in millimeters, even though it says for example 10 millimeters, generates an image of 10 cm. The same is happening with the speed, I have to put 80 if I want 800. What can I do? (I also have this machine connected to a PC co windoows 10, depending on the conditions I choose which one to use)

Show the LightBurn settings and the machine settings, please.
