I am building a new laser engraver/cutter and I have purchased a Two Trees K30 30 watt laser that has crosshair positioning. I use LaserGRBL (latest version) to control the machine, but have no idea how I can take advantage of the crosshair feature. I think that I need to put in some offsets somewhere to make adjustments for the crosshair position and the actual laser cutting position. I hope someone can help me with this question. Thanks.
