Most of the time when I open lightburn and begin the lower left, my starting point, of my shape has a blue dot identifying that it should start the sketch in the lower left corner. When I opened it this time there is not dot and it will not start once I click begin. How do I get this blue dot back?
If it’s the dot I think you mean, it’s green, not blue, and would be the “User Origin” dot shown when in User Origin or Current Position mode:
