Any piece of glass is pretty flat. The X wheels could have been a problem as the nozzle is supposed to move smoothly across a plane. The bed cannot have any wobble that might be caused by improperly tightened wheels on the carriage.
I do not have a tri-square unfortunately hanging around...
I used a big flat metallic ruler I had to make sure that the Z axis 20x40s were the same distance top and bottom, which they were.
I did change the X-Wheels.. Twice to be certain, but it didn't seem to affect the irregularity of the pattern.
To be fair, it did change the pattern.
(This is the OLD Wheels)
While this one (which is also the picture on the original post above), is the new wheels.
The probe points aren't the same, I think the old one was 8x6, while the newest picture is 6x4.. but still, a similar "irregular" pattern appears.
As for the bed, I made sure to tighten the eccentric nut as far as that there was no wobble to the table. It seems to be pretty stable!
I do believe that it is a "wheel-area" issue.. Could by any chance the eccentric nut to have somehow "failed"? Like if the circle inside the eccentric nut isn't perfect?
Thank you very much for your input! <3
