Thanks for this thread. I'd taken a bit of a break for school but started printing again last week and have been getting increasingly more frustrated at the curling.
I found [www.thingiverse.com] and printed just the default model. It turns out that a) these boxes are super useful b) it's a good test for curling and c) I've got another weird problem which I will detail below. I printed it once on 3M Blue tape without any cleaning. I ended up printing at 220C (seemed like a good idea at the time) and found the curling issue, as well as badly discolored print. Next go around I tried glass with some Elmer's Washable School Glue Stick Disappearing Purple which we had lying around the house. I did some searching and I think it's PVA, though I can't find the source of that information now. That yielded a far better result but I still have curling right at the edges. Someone in IRC then mentioned to use the 3M tape with acetone. The print stuck really well to the tape, but the curling was still an issue and it lifted the tape off of the glass.
I'm going to try removing both fans for this print and seeing how it fares, though I am concerned about sloppiness as Nick mentioned. As far as hotend temperature, I've heard that different brand of plastics are better at certain temperatures, but the calculator has its own idea of what temperatures I should use. Should I stick with what the calculator recommends? Also when you say "print the first layer a little more squished down", how would I go about doing that using KISSlicer? Is that Ptr G-code Prefix Z-offset negative/positive?
For the oddball question (and feel free to redirect me if it shouldn't go in this thread), I've got the attached image happening. This has happened each time in the same spot on all three attempts. I ensured the bed is decently level but it keeps happening there. Since it happened each time it could be the model, it just doesn't seem likely.
