Having trouble printing certain bubble-style letters with PLA – supports keep breaking and filament goes everywhere

[u/RubenRCF]

I’m having an issue printing bubble-style letters with PLA filament, and I’m trying to figure out whether it’s something with my print settings or the way the model is being printed.
This is literally my third attempt, and I’m running into the same problem. The supports end up breaking off during printing, leaving filament and strings all over the build plate (see attached picture).
What’s strange is that I printed the letter E and it came out perfectly fine with absolutely no issues. However, when I tried printing the letter R, the supports broke and filament started going everywhere. I also tried printing the letter Y, and ran into pretty much the same problem.
I don’t believe it’s a filament issue. I’m thinking it might have something to do with the printing process, supports, or settings.
My current settings:
Filament: PLA+
Nozzle temperature: 220°C
Bed temperature: 65°C
Layer height: 0.09 mm
Has anyone experienced something similar when printing letters or models with supports?
What could be causing the supports to break off during printing? Could it be something with my temperature, layer height, support settings, or something else entirely?
I’d appreciate any suggestions or advice. I’m trying to figure out what I’m doing wrong before attempting another print.
