John, Looks ok, but it may be something "simple". You could always do a manual test (and apologies if you have already done this) by manually setting the G54-59.3 origins by moving and touching off each in turn. You should then be able to go to each origin in turn using G55 G0 X0 Y0 Z0 and so on. What happens then?
I can't see it affecting your method, but I find G10 L20 much more convenient than the L2 version of that command. It saves calculation because the L2 offsets should be calculated form absolute machine co-ordinates, whereas L20 works all that out for you . Drive the controlled point to each fixture reference point in turn and touch off at each, before you begin the program. Is there a G92 in effect anywhere? What happens if you put G92.1 at the start of the program?
