hi all I am running 1610 ballscrews on my y axis with 3nm nema 23 motors and no gearing, and twin 1610 screws on my x axis with a single 8nm nema 34. my drivers are em806 drivers with a 68v power supply. all axis are on hiwin 20mm rails. roughly what rapid speeds should I be able to achieve with this setup not taking in to account weight of axis etc. thanks all
