    I recently did a carve where I set the origin in the near the center of a hollow deep carving. Because I could not lift the bit high enough to clear the surrounding material, I did not want the bit to leave the middle of the carving. The 3D Viewer showed a phantom move to the (0,0) (lower left/bottom) which scared me. I checked the g-code editor (very nice feature, by the way) and searched the beginning and end g-code and did not see this movement. Due the the large size I did not search all of it. I have tried to attach an image below of the job. I successfully ran the job and the movement did not happen, but I found it very disconcerting.... :(

    did the gcode have any G53 moves?
    previewers typically do not know how to handle those
