Assembly: X-axis skewed

Hi all
I have a problem with assembly. When I've attached X-Axis to Z-Axis the X-Axis looks visibly skewed (see photos) In order to make it align correctly I need to apply force to a point that it bounces back to previous position.
Any help on what could be causing this? I've already disassembled and reassembled the part but I don't see what I could be doing incorrectly.
Is it my mistake or does some part have a defect?

💡 yes, you'r whole x-axis assembly seems to be too long !

➡ you've either used the screws at the end of the right x-axis idler to tighten the belt.
they are not for this purpose ! they are there to get the length of the whole x-axis assembly aligned so that no force in +/- x-direction will be applied to the z-axis rods and the spindles.
➡ or you've something stuck inside the rod holes at the x-motor end or x-idler part, which avoids that your rods sit completely inside the part.
maybe you've to clean the holes first with an 8mm drill (for wood-purpose -> so you can clear the edges of the stud hole as well) before you put the rods in again.
💡 assembly tip: use a tiny amount of liquid soap at the end of the rods. this makes it much easier to assemble them into the holes.

Hello JeffJordan, thanks you for your answer


➡ you've either used the screws at the end of the right x-axis idler to tighten the belt.

if we are talking about those screws then the problem is even with them totally unsrewed


or you've something stuck inside the rod holes at the x-motor end or x-idler part, which avoids that your rods sit completely inside the part.

There doesn't seam to be anything in the holes, and I had no troubles with inserting them.
The holes for right part have length of ~27mm and it look like the rod is going all the way in
The holes for left part have ~38mm and also it looks like rod is going all the way in

I think the problem is that holes for the rod are skewed, look below (the photos ware taken with the part disassembled so only one part with rods at a time).

hmmm.... seems that the printer which printed the parts was severely misaligned or something has gone wrong with the print. in my eyes they are "faulty"; show the pictures to the prusa sales team. i guess they will send you replacement parts as soon as possible.
