I found away around the issue by adding my settings form CSV to JSON converted information to the prefs.ini as a JSON string. Work fine, but a hassle to do it for each board I make.
Thank you for testing it. For me, it would be great if there was an option to import a CSV file in the user position setting. With Z-axis would even be better.
Your prefs file is just JSON, so it’s pretty easy to add these by hand. Go to File > Open prefs folder, then close LightBurn, and open prefs.ini - you should be able to find what you need in there without much trouble.
But I like to use the “option” to have my laser cutter work like a pick and place machine for PCB board making. And so I need to load a lot of different points for different boards.
That’s a high-level description, but I was looking more specifically for why you are using stored positions for this, instead of just making GCode that moves the laser to where you need and running that.
