I got my Ender 3 a couple weeks ago. Within a couple days of test prints, I was able to get it working pretty well. Prints looked great. However, I installed a more permanent solution to my X-Gantry binding issues and now print quality is down again.

Layer separation issues

The bottom .25" of the calibration part looks absolutely terrible, with hideous layer separation issues, while the upper .75" looks flawless. I have little idea what could be causing this issue.

The only possible failure mode I can think of is that the bed isn't the right distance from the print head, but even fiddling with the knobs doesn't yield any better print quality than the print on the right of the first image. What can I do?

I slice with Cura and can make my profile available if it would be useful.

Well, you have several problems with your print. One that could be affecting your print is the nozzle temperature. The print looks wavy and has a lack of adhesion, so the filament is not flowing properly, causing under extrusion and will provoke a clogged nozzle.

Try to increase the temperature by 5°C and do a small test, don't wait to waste material and try another 2-3°C more.

Try to reduce the printing sped; try reducing the feed rate on your printer to 90% or less. While printing you can reduce the feed rate to see which speed works better at your printing temperature. I prefer to do this first rather than change the temperature; If you notice that your print gets better at lower feed rate then change your temperature higher to print a higher speed.
