I have the Two Trees 55 pro and have downloaded the Lightburn software. I am having issues with the homing and the laser keeps hitting the sides. Is it possible to home the laser in the middle of the workspace?
Short answer, NO.
Long answer, HOME sets the 0.0 position of the Machine coordinates. This is only determined by the limit switches. This design allows you to have accurate repeatability using Absolute Coords as the Start From point.
Origin is different. It is the start position of your Workspace in Lightburn. It can be located anywhere on the machine or workspace. It sometimes creates confusion because Lightburn operates in Quadrant 1 of a graph.
I have included some reading and viewing material to help you with working in the coordinate systems.
