Newbie question. I have a cnc 3018 with interchangeable router and laser heads. Used router many times but first use of laser. I design on my Mac and save GBRL to load on a Windows 11 (underpowered) machine connected to my 3018 machine. When I examine GRBL file, it shows moves of no more than 2 mm in any direction. The project consists of just two images and preview works well. GRBL and LBRN file attached. Any help would be appreciated.

I can’t help with your Gcode question, but why don’t you load Lightburn onto the Windows computer and run the lbrn2 file directly. You are allowed to install on 3 computers and Lightburn does not require a lot of HP to run. Might save you a step in the process.
Those motions trace out the gazillion tiny vectors along the edges of the figures, which eventually trace the entire outline.
Dropping the G-Code file into a simulator shows the result:
The Bounds seem about right, with the directions depending on which way your machine is set up relative to the simulator.
Applying the Optimize selected shapes tool would smooth the outlines and might reduce jank from tiny motions choking the GRBL path planner.
Thank you for the suggestion but due to personal factors, this would not be optimal.
Thank you for taking the time to check and respond. I think this is due to lack of attention. I saw the G90 but overlooked the G91. In my defense, aal of my router work has been absolute addressing so expected the G90 and sometimes we only see what we expect. Do you know if absolute addressing can be used?
No clue. As long as the correct result pops out, the exact G-Code pretty much doesn’t matter.
Having written entirely too much raw G-Code, I now regard it as an intermediate language between the CAD design and the mill / plotter / engraver. Whatever those programs agree on is fine with me. 
I hate it when Look! A squirrel! that happens …
Many thanks - nice to know this community is active.
