I forbid G20 on the Mori Duraturn in my lab for that exact reason. It has a Fanuc 0i-TC. I figure 21st century engineering students should develop some feel for metric measurements anyway. Just to be safe I also require G21 on our Mori NVX mill even though it uses a Mits control that handles it better.

So pardon the OT post Fanuc is making me pull my hair out. You'd think a cnc control built within the last 20 years could handle switching between G20 and G21 modes! It's a flippin command line code that can be issued in a file for goodness sakes! We bought a used machine that was being used in G21 mode. And I've been banging my head on this thing for a week. Can't figure out why all of the work coordinates are so screwed up, reset them and then they are messed up again, G91G28 commands won't work and keep over traveling (but G90G53 does) and the home positions keep moving around. Turns out its all because a stupid Fanuc 180iM control built in 2003 can't handle switching between G21 and G20 modes without 3 power cycles, a couple of parameter changes and completely resetting all the work coordinate systems settings. FOR REAL!!!!!!!!!!!!!! Even Mach3 can do this right! If this is the case why even have G20/G21 available as a G-code! It should only be a parameter setting that can't be changed from a file. This is even more annoying than G92 or jogging a paused program, at least a power cycle can fix those screw ups. Todd Zuercher P.
