As far as the acceleration goes, i have increased it to 600 and that seems ok with hardly a noticeable ramp up in acceleration.
Ok well that's a nice safe setup thou I'd be inclined to up the Accel a little. Having higher accleration can actually reduce cycle times more than velocity on some jobs, mostly those with short moves and direction changes like engraving etc.

If I was running that setup I'd be tuning it at 4500-5000mtr/min with 800-1000s/s.

Speed you cut at is mostly determined by the material, cutter and machine ridgidty etc. It shouldn't really be based on what you feel comfortable with in terms of being afraid or scared to push machine. Your far more likely to break cutters and ruin work by under cutting than you are ever likely to break the machine.! . . . . The machine it's self will soon let you know when it's not happy.!

NOW get them switches on and make some Bloody chips. . .
