Ugly Layer Issues, Help!

I have not yet checked bolts and belt on drive part, cause I dont want disassemble now (it will be my first checkif I'll disassemble)

I tested this issue :

Result layers are kinda better, but we can still see continus z-artefact in layers height (similar to the z threaded rod frequency) . Tomorrow I'll check in robo3d slow speed (last step before disassemble and check the drive part)

Important think for me, that layer quality are not the goal (at first time) cause I'll use robo3d only to build small prototype and I need only correct dimension (in millimetre) and not a very nice surface quality (but it will be kinda annoying and not professional)

 

I found an ugly issue in the assembled drive part. The low speed motion dont correct the problem. Finaly I disassemble the drive part, bolts and gear are correctly tighten, but, I found an ugly problem witht one 12" Slider (one is ugly deformed and the slider got litle x - z - move during sliding on the deformation)

At this step, I cant correct the slide manualy and I think need a new one. Waht I need to do now with my robo3d ?

 

Contact team robo and get a replacement rail. Unfortunate this happened

 

What would cause that?

So after a lot of annoying print bed quirks I think I've gotten the thing working.... although I may have accidentally stripped a screw in the process of tightening :/ (so far it hasn't been a problem). Sadly, another problem has come into the spotlight that I've also been getting for a while, which would be a series of minuscule holes around the entire print. Pretty sure this is a common issue, but I just wanted to know what I could do to solve it.
