I wanted to give my 2 cents on this topic. The Luban software doesn’t provide enough control of the machine. Lightburn gives me the ability to remove the crosshair offset and turn the laser on for alignment. This was a gamechanger since when using lightburn the first time you run a job the crosshair didn’t return. The only way to get it back was the use the job button (hopefully you have a small job that was sent from Luban) or turning the safety key off and back on. This started becoming tedious so I opted to use the laser beam and remove the offset. Now I know without a doubt I am within 0.5mm of where I need to be. It was difficult to know with the light scattering crosshair and was often very slightly off center (perfectionist in me couldn’t cope with that lol)
Just know that when you use Lightburn, to have a great experience you will need to stop moving the laser head with your hand and use the controls in the software. There is a fluke between the Lightburn software and the machine. You will have to tell the machine to go -400 on Y (G10 L2 P1 X0 Y-400) then the Lightburn control and location, origin and absolute position work as expected.
