That's absolutely correct. We shoot for 600 (both ways...which is important). All 3 axis at 595-600 and your making very accurate parts. What was wrong with your memory? I have lots of different sizes. You need to zero memory 3-4 times in Di G0 3000 command mode and then add your extra memory and do it again...then your set. Its a little song and dance to add a little bit of memory to a fadal.
