Sorry, first post. Grbl controller, neje 7.5 diode laser, custom frame (linear bearings, the frame was an old expensive Commercial 3d printer). So, I have 3 layers: Image, Fill (just some text), and line. All layers look perfect on their own, but after layer 1, the laser is shifted ~6mm to the right. So layers 2/3 are aligned with each other, but not with layer 1. I figured before I bang my head on the wall too much, maybe someone has seen this before. I really don’t think it’s mechanical, but I also wouldn’t know what to look for in the gcode, I am used to marlin, so grbl is greek to me for now. I don’t see anything moving x by 5-6mm overtly, at least. Any ideas? Both first layers are 4000/s80.
