Wow - effective limit switches are a must at those speeds I expect ;)

Even 4m/min was hairy compared to what I've been used to previously when I tested it last night.

Oh and a quick question or two: I'm running the same test job "cutting air" to see what progress I'm making as I make mods etc. to the machine and I notice that whatever max speed I set the motors to is what the test run seems to use as its rapids - I'm assuming that's normal behaviour?

The other thing is when I first power up and load MACH3 the motors always seem to need one axis setting up in MACH before they "remember" the settings from the last session?
