I don't think it matters too much if your carriage wheels are badly aligned or anything like that. So long as they're round and they roll up and down the tower, they're good....With power on to the motors, you should not be able to move the effector. If there's any movement or clicks (i.e. play in the bearings), you need to fix that.

I don't see any kind of tensioning on your drive belts. Any play in the belt will cause distortion. You can print some simple belt tensioners.

What is really important is that each pair of diagonal rods forms a parallelogram. If you draw a line through the bearings at the top of the rods, and a line through the bearings attaching the rods to the effector, those two lines *must* be parallel. The two rods must also be parallel, and the same length. If you get that right, the effector will remain horizontal, no matter where it is moved to on the bed. Any tilt of the effector is going to result in distortions.
When you say is *almost* exactly the same, what are the differences? Can you perhaps exchange parts between the two printers to identify which part(s) are faulty?
