A5S Z axis Uneven gantry operation

Type My A5S is new and came in the box knocked about, I have it all set up correctly now but as soon as I try to home the Z axis or move the gantry down it comes down uneven and starts a loud grinding noise and stops.

I have taken out the whole left hand side motors and screw and put it back together, have tried to adjust the screw and it will not come down level and jams. what can I do?

Cheers Bernie

    Welcome Bernie! The lead screws probably need some lubrication. You can remove the old gunk with a rag and ethanol, and then replace the lubricant with a better option.

    Also inspect the motor couplers, make sure they are installed straight and are not bent or stretched.

    Hi Samuel, it isn't a lubrication problem and the couplers are fine and straight, I have checked the screws. It is a brand new 3D printer and I haven't  a print on it. I have checked the Y and X axis's and they work. I Looked at the Z-Axis discussion on the forum, I don't know what or where the clutch is but shouldn't have a problem with it if it's new. I am not sure where to go from here but really disappointed.

    I'm sorry @Bernie , sounds frustrating. May I ask, how have you confirmed it is not a lubrication problem? Is the X axis level?
