These comment suggest you guys don't really understand how G-code executes. As with most programming languages, g-code has a very well-defined execution order. The order in which things appear on the line NEVER matters in g-code. "M3 S100" is exactly the same as "S100 M3". Similarly, "M6 T2 G43 H2" can just as well be written as "G43 T2 H2 M6", or any other order you like. They will all execute identically, barring a G-code interpreter which violates the RS-274 specification..
