Frage Play in Z axis..

Hi Can you repost? This topic just disappeared?

Most likely the brass lead screw nut is tight but still has play. Make sure with the gantry taken apart that the brass nut is SOLID

I took it all apart this morning i can see wear on the z lead screw. So it was bent, as when i first built and tested it there was a bit of noise as the z axis went down with the kress attached, seemed ok going up but when lubed up it seemed to go away. The brass nut was tight, but trying the X lead screw in the brass nut for Z axis i can see some play as i move it up and down a bit. So i might aquire another one to be sure.
