<p>I was having some issues with printing, most noticeably in this picture:</p>
<p><img src="https://i.imgur.com/oCKwkBj.jpg" alt="Noticeable layers in print" title="Noticeable layers in print" /></p>
<p>The layers are very noticeable and sometimes have gaps, and the overhangs don't print very well (although the former is more of an issue). I just calibrated my E-steps so I don't think that is the issue. It was doing the same thing before I upgraded anything (i.e., I had issues on stock hardware).</p>
<p>My printer is an Ender 3 with the metal extruder upgrade (which replaces the plastic parts as seen <a href="https://rads.stackoverflow.com/amzn/click/com/B07B96QMN2" rel="nofollow noreferrer" rel="nofollow noreferrer">here</a>), an E3D v6, printed fan duct (Bullseye), glass bed, BLTouch, and vanilla Marlin. Pictures of it are also in the below album. The printed upgrades were printed on a Prusa MK3S and don't have the same issue.</p>
<p>I am using Hatchbox 1.75 mm gray PLA, printed at 215 °C with my bed at 60 °C. I am using Ultimaker Cura 4.1 but was also having the problems on an older version of Ultimaker Cura (maybe 3.6, but I can't remember which it was). The problems also existed with some Hatchbox 1.75 mm black PLA but I used the same roll on my Prusa MK3S without any issues, so I'm not sure if filament could be the cause (although it is a different printer so it's still a possibility).</p>
<p>I have tried at different printing speeds and the problem still persists.</p>
<p>I also recently tried varying the temperature during printing (first up to 222 °C then down to 200 °C) with no noticeable difference.</p>
