Andy; I could be persuaded to have some sympathy for this viewpoint, actually. > If G-code simply moved axes in absolute machine space and everything else > was done in the pre-processor then thing would be a great deal simpler. I wonder what will happen when they get *two* extruders going (support + final materials) and find that they have two slightly different heights of extruder nozzles - maybe re-invent tool offsets, but call it something different. (in my CNC mill, I don't worry about tool offsets, but if I had some tooling system that allowed me to accurately set tool lengths, the story would be different) And, I guess, conversational programming (e.g., laying out bolt circles) could just generate the GCode, sans subroutine calls, so I can half- sort of understand the comment, too.
