I misread your pevious post and thought you had PK series motors. I think those motors just don't have enough power, and need to use a much higher voltage to use the power they do have. I couldn't find a torque curve for those.
Max speed is used for rapid moves only. Unless you try to cut at an F faster than the Max speed. Yes, every move accelrates and decelerates. You might want to try a much lower start speed, say, 25, and a then slowly increase the acceleration until you notice missed steps. You may be able to increase the max speed as well.
I think the bottom line, though, is you need more voltage and / or bigger motors. More voltage alone may not be enough. Perhaps Dave can give you more info.
