How do i get my laser to stop above my project rather than to the bottom left? See photo:
Second how do i get rid of this prompt with the water and air screen?
Set Finish Position in the Move window.
For Ruida controllers, that’s handled in the controller and LightBurn has no way to change it.
Depending on which Ruida controller you have, it’ll be in something like Machine Configuration accessed by poking the Menu button on the console.
You (may) have a few choices:
- Do nothing
- Return to machine origin (probably the default)
- Return to fixed position (you set coordinates)
The manual for your controller may give the options, but blundering around in the machine’s menu may be more productive. 
Set your origin beforehand to the materials with a user origin…
Not too sure about the air and water thing, what exact controller is it?
