Indeed I understood you have an A350, I have experienced the same issue on my A350. What solved it for me was ensuring that the coordinate system was set to workspace coordinates. Before I start camera capture, I make sure to home (G28) and switch to workspace coordinates (G54). I have the same in my “End GCode” so that it’s guaranteed to be in workspace coordinates when the job is finished.
However, if you’d like to go a more customized route, I have released a new version of the tool that can be configured using a config file: Release v1.0.3 · PolymerPrints/SnapmakerLightBurnHost · GitHub. You have to run the tool once for the config file to be generated, then you are free to edit. Note that the config file is only read on startup, so the tool needs to be restarted for the changes to take effect.
