I will confirm but I’m pretty sure they are NC per the instruction page. I’m thinking that with the dual endstop firmware, it just won’ t drive to negative coordinates because it assumes (maybe not the right word) that after G92 X0 Y0 that it shouldn’t go negative from there since that should be the endstop. (I was actually just issuing a manual G92 out in the middle of the machine since I was just testing, not actually doing a home command.) The gcode looked good and the simulation ran properly in camotics and show travel looked correct in repetier. (Below is the little doodle I was cutting just to see how well the laser would cut.) If I had center of part selected as origin, when it went to cut, it should have started in the NW quadrant, but it just moved up and down along the left side, then for the SW quadrant it just seemed to skip that and the SE quadrant just went left and right along the bottom, then the NE quadrant cut correctly. Once I switched to lower left of the part in CAM for origin, it all cut fine. A bit of an oddity, and something I am going to try to cypher out, but not a big issue as everything works fine so long as I stayed in positive X & Y coords.
