I'll be using dual rack and pinion and if necessary I'd be happy to have dual 900 or even dual 1200 steppers. However, do larger steppers restrict you with their top speeds and direction change and acceleration abilities.
Has anyone built a heavy gantry for plasma cutting and are just using brute force to get the necessary acceleraton and speed for plasma cutting.
Would big steppers be OK or are there reasons why servos are better with a heavy gantry doing plasma.
Thanks,
