LB V1.7 to V2.0 to V2.0.05 had several evolutions of change in how LB used G54 work coordinate offset, Move window jogging (with and without ‘continuous’), device setup work area Origin selection, and on the Laser window ‘Start From: Origin’ selection. You may be experiencing one or more of the side effects from release to release of these changes.
This thread may help you figure it out or diagnose for a workaround -
