That definitely sounds like a likely cause!
You could also try twiddling the red emergency stop on the front of the machine. When I first got mine I had trouble starting the whole machine and that was the fix, and who knows 
might reset something.
I also missed a piece of packaging behind the gantry inside the machine (in front of the fan) that was preventing the machine from homing/completing its start-up routine.
But these were all first-time-operation hurdles, and I do think your answer is the more likely candidate @jkwilborn! Iād definitely test it after moving the job a bit further into the work plane. I also give some rough guides in this post: How to use Gweike Cloud with LightBurn + tips, tricks & FAQ
