Hey, first of all thanks for a awesome cover model.
Too bad it is reeeeeally painful to print.
My printer is now starting to print it for the sixth time. So far this one is the best try (now at 7%).
I am printing it on its back to get nice flat surface on the outside without need for any support (so I hope).
I couldn't get the print start nicely for the first five prints and I thought it was because my filament was not suitable for any reason or the setting didn't were off. I am printing with eSun Luminous GreenPLA.
I tinkered with speeds and stuff and managed to get that first layer to stick really nice. But once it started to do second layer prints started to string and did not stick.
That's when I started to take a better look at the model itself after slicing. And I found the problem, after the first layer (note that I am printing at 0.15mm layer height) second layer starts printing its exterior lines on basicly nothing and this goes for first 0.45mm. After that the model is pretty much fine and does print on last layer, but I still see some similar problems, but I think it should still work.
To solve this problem I tried and cut first 0.45mm from the model leaving back thickness still somewhere around 1.5mm or so. It should work.
Now printer is doing its job steadily and so far so good, 10% done.
Ill post again when I know how this works
