Recently got a Creality Ender 3, and went through the usual troubleshooting issues of bed leveling, wheel loosening, filament kinking, etc. I thought I'd be able to print on a larger scale and handle the 5 pieces that come together into a fantasy Pirate ship from printable scenery. When printing the first piece, the top of the bow, I noticed some layers under the railing had come loose, and thought it more an issue that the railings had no support, though the site says you don't need it. Second part, lower bow printed with no issue, but the curved areas seemed a little rough. Upon printing the third, the midsection the issues came back, but worse, and I'm worried the problem has gotten worse.


This is the main issue that made me stop all prints until it was fixed, I think its called blobbing / pimpling?

Noticed these strings inside as the infill was being printed. Wanted to share it as another symptom of what might be wrong.

Any advice for how to fix it? I'm at my wit's end...
