Strange layer separation issues on Ender 3

  • 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.

    The answer now seems brain-dead obvious now. Hindsight is 20/20, amirite?



    I had a decent filament clog in the extruder past the end of the Bowden tube. This was resolved by sticking a nozzle cleaner rod up and down the filament path from the top of the extruder block several times and clearing the filament jam from the bottom of the Bowden tube. The printer works flawlessly now.
