Default PrusaSlicer RatRig Settings - Voron Cube - Quality Issues
After using SuperSlicer for a year I wanted to give PrusaSlicer a try. I installed PrusaSlicer, set the default Print, Filament, and Printer Settings. The only changes I made were to the custom gcode based on RatRig's docs (https://os.ratrig.com/docs/slicers/#prusaslicer). Based on my previous experience, this seems like a part cooling issue? Looking at fan speed, it's 30% for overhangs, and 0% for everything else. If that is the case, could someone help me to understand how to modify the Filament Coolings settings to get a better result? Also, maybe it's not part cooling? I'm certainly open to suggestions and I can reprint this cube however many times that is needed.
Edit: I also forgot to mention that I'm running the 4028 fan. It seems that the spin-up time of this fan is kind of slow? Maybe I have something configured incorrectly. In SuperSlicer I had Cooling fan Kickstart duration set to 4 seconds. I found fan -> kick_start_time in Klipper, so I set that to 4 (seconds) and set SuperSlicer back to 0; it also seems that PrusaSlicer does not have this setting and because I'll be switching between slicers, I figured solving it in Klipper would be good. Here's my overrides for fan:
I'm also running the Mosquito Magnum hotend and the Tri Horn part cooling duct. The filament is in a dryer and has been running at 75C for days.
TLDR: I think I need more part cooling, any tips on how to do this well in PrusaSlicer?

RatOS comes with STARTPRINT and ENDPRINT macros that you can call directly from your slicers. This way the printer knows how to start a print, and you can there easily switch between slicers without worrying if you changed anything in another slicer.

After staring at Layer time, Fan speed, and making changes to the Filament -> Cooling settings... and flipping back and forth between those three things, I eventually could see some Fan speeds that were doing what I was looking for; essentially some fan all the time, and higher fan speed for overhangs. I'd love to hear some more perspective on what others do in this scenario. I did a print and the cube looks a million times better.
