2300 IPM on lightweight optical stages is not too surprising. But, I can't
imagine a large milling machine moving that fast.
Ahh, I see where the odd number comes from, ~ 1 M/S.
Anyway, that's 191 FPM, or just over 2 Mi/Hr, which doesn't seem all that
fast. Still, my machine rocks when it accelerates to 100 IPM, I wouldn't
want to go much faster.

That large CNC router I use at work goes 900 inches a minute on G0s. It don't
seem fast when you need to take 2 or 300 passes ten feet long....

P.S. Yes, I cut surfacing passes on the g0 to max out the speed. On G1, it
will only go 2 or 300 Inches a minute.
