Bended ballscrews. What i can do?

Hey Vagelis,

I'm fairly sure that my (considerably shorter) z-screw isn't 100% straight - they could really do with packing 'em in a rigid box as opposed to cardboard/bubble-wrap, but who knows - it could as easily be a factory issue..! I guess it's a bit of a 'get what you pay for' scenario - having said that, it hasn't really caused me a problem. I think your screws look a lot worse than they perhaps are because the bearing blocks don't appear to be fastened down hard and everything's moving around, which is exacerbating the whip.

This is a vid I made when I first got my steppers running:



It looks REALLY bad, but when everything's bolted down it's actually okay. You could really do with having a look at this with the hardware fixed in place, as opposed to bouncing around on a couple of planks... That'll give you a better idea of how bad (or good) things are.

Chai seems like a decent guy. Always been very helpful on the few occasions I've had to contact him for advice.

I have told you this in an email but obviously you don't believe me.? . . . . Your cordless drill is exagerating the Wobble greatly and when on the machine and fastened down and aligned correctly it will most likely not be a problem. I have seen worse being used without problems.!!
