PLA Curling with Glow filaments on overhangs
The issue:
I'm printing out a large unicorn toy for my daughters (that would be pretty weird if it was for myself. Come to think of it, this parenthetical makes it a little weirder but I'm leaving it in anyways). I keep having print failure because of the toolhead colliding with the print. I discovered it was a result of curling of PLA. I've been running the default settings using a high flow E3D Obxidian nozzle (.4 mm). I've tried this with and without the MMU. I'll also note that this problem doesn't exist on the first few layers, it only becomes pronounced on overhangs after layer 20 or so.
Note:
This doesn't happen as much on standard PLA, it's only typical of glow-in-the-dark PLA.
If I can't print glow in the dark rainbow colors with pink, blue, and gold, then my girls will only have to be happy with matte-colored prints. They'll probably grow up to be something boring like librarians (that's just what I think of as boring, I realize/hope not all librarians are boring).
Things I've tried (that didn't seem to make a difference):
1. Slowing the print down to 70%, 50% and even 30%
2. Increasing wall thickness/infill using gyroid for part stability
3. Decreasing the nozzle temp down to 210 (default is 220)
4. Leaving the door open
5. Random seam positioning
6. Using different brands of PLA glow filament

A fairly common problem with steeper overhangs.
You might reduce the number of perimeters and experiment with printing external perimeters first (advanced mode) or trying Classical generation instead of Arachne.
Cubic fill might be more stable than gyroid here.
Cheerio,
