Re: Acceleration rates..

I'm working through some design disicions and trying to get my head around
mill acceleration. My plan is to mill foam predominantly. I'm wondering if
acceleration rates are really a concern or not. I would figure that not to
many people want there system to take 5 seconds from a stand still to
accelerate to 10 ipm or something but.. what is acceptable? I would like to
rapid @ ~400IPM and be able to accuratly mill at up to 200-250IPM. The
system I'm looking to build has a fairly large foot print with a ~200lb
gantry. Obviously 120 oz-in steppers won't cut it [ pun intended] but..
should I be able to go from 0 to 250 ipm in 5 seconds?
Does it really MATTER? Am I looking at the wrong side of the design??

Opinions welcome!!!
