I am finding when I pause a laser Job and then resume the X,Y origin changes. This trashes the print job. This also happens when I open the enclosure door. Both causes are intermittent. Anyone have a solution to this problem?
I’m not sure if it is the same problem or related: When I use Lightburn to generate GCode, it creates Code that uses relative positioning. When I pause such a job, the machine “forgets” about that and switches to absolute positioning, which causes all movements to center around the origin. I never looked if I can switch to absolute positioning, I just do no longer pause the jobs 
But if in your case your origin moves but the movements continue as expected otherwise, or you use Luban, then it is most likely a different problem, and I’d contact support on that.
