I agree if everything is done correctly it isn't an issue. I was tossing out the implications of leadscrew and motor just to defocus on them and focus on other parts. The last sentence of my post said "takes its toll if one tries to get to aggressive". Agressive in that they overload a mechanical stresspoint, for example a non backlash plastic leadscrew nut isn't an issue in itself when loads are properly tuned, but if the acceleration values are too agressive over time the wear will lead to ever increasing backlash. I think were on the same wavelength, just my poor commumication skills.... Did you get a chance to be a second set of eyes on my new numbers?
