Man, it seems impossible to get a good first layer on this printer.

What could be causing this? I've already tried various things I found on forums and in videos.

I aligned the X-axis. I tightened both belts (without making them overly tight). I tightened some screws while leaving others with a bit of play.

I added Z-axis supports to make the structure more rigid.

I'm using linear rails, which made the Y-axis and the bed very stable and free of wobble. I swapped the nozzle for a "Unicorn" nozzle.

I tested two different build plates: the original one and a PEI plate. Before starting the auto-leveling process on either plate, I heated the bed to 70°C for 10 minutes and ran the auto-leveling (photo attached). I did something similar for the nozzle (240°C for 10 minutes).

During printing, I kept adjusting the Z-offset because it was too high. If I raise the Z-offset, the ridges diminish (though they don't disappear completely), but on the other hand, gaps appear in the first layer along the Y-axis.

I don't know what else to try. It seems impossible.

Hey guys. I've got this one and I didn't understand if it's only one piece or a set that I can change the nozzle if I want to. The idea is use a 0.2mm unicorn nozzle some times, since the one that came in this hotend is a 0.4mm.

Hey guys. That's my first KE and I'm trying to calibrate it but I'm struggling to get the smoothest in this set. For me none of these are good enough. But maybe my eyes are fooling me haha can someone give me some tips?

That's a Masterprint PETG printed in 240 °C and 80 °C nozzle and bed.

Average velocity are 110 mm/s and first layer 30 mm/s

My rods came in different lengths. Basically, I can remove the one on the right, but it’s impossible to remove the one on the left. The right side of the bed was wobbling and a deafening noise, and after investigating, I reached this conclusion.

So, is that it? If I want to switch to linear rails to try and reduce the deafening Y-axis noise, I’ll have to saw the rod? I really regret this acquisition 🥲.
