I see this asked on the Ortur laser forum lots of time so documenting it here might help others too.
- Set “Start from:” to User Origin and the center of “Job Origin”
- See if that green origin mark is the center you want.
2a) If not, add a layer with a circle around your design which causes the origin center desired.
2b) Set the layer to Show but not to have Output.
- Group it all.
- Click the ‘tag’ icon below the Add Text icon so the laser head will move where you click
- Click on the green origin square/indicator centered on your design so the laser head moves there.
- Click the fire button in the Move tab if your laser is a diode laser otherwise use your machine sighting laser to see where the origin and center of your design is and center your work based on the laser dot.
