Hi, i have had my chinese K40 for a few years now and never really had any issues with it. Recently i replaced the tube and i am not sure if this issue is related to that. I am using Lightburn 1.7.03. When i start a burn the laser comes on right away wherever it is (usually home), apparently with reduced power, but it is drawing lines that get in the way. Please see image, it shows what’s going on. I have no extra g-code in my settings. Maybe someone has had this before and can help? thanks!
Maybe the solution is here;
