It appears that tool table entry 99 is used to store these offsets. But when I make a mark with a tool, touch that off, them put the camera on that spot, and store that dro displayed value in #99 of the tool table, then run _camoff.ngc by clicking on its button, the machine move at max rapid from looking at the target with the camera, to someplace near those 0.000 0.0000 values, putting the machine back over the mark it made, but then it immediately runs back to where the camera is once again centered on the mark, hitting that point precisely. These subroutine calls (_camoff.ngc, _camon.ngc) make use of the values in #5211-12 for the XY info, but these values are 0.00000 until a G38.x has been run to initialise them with valid data. I am thinking it should be using the data for these calcs from the G53 section of that table, not the G38.x scratchpad. So, does anyone know of the method intended to be used to determine the offset between the camera and the tool? IOW, what the initial calibration does and in what order? Thanks.
