For the past almost year, I have been working on a project printer that I bought; the original frame and parts were from a CR-10 S5 (with a 500x500x500 build size) the first couple of test prints worked, but they were not optimal with many issues, elephants foot, layer line issues, and a couple other minor issues, some of the problems I was able to fix by tweaking hardware.
But most of my issues I could fix by changing my slicer settings; I currently use PrusaSlicer v2.5.0; I used to use Cura slicer; I swapped slicers because of the easier-to-use interface and the number of features built into the base program. Overall I prefer it for its interface and configurability, which makes it easier to swap machine settings from my Ender3 to my project printer. As well as built-in support for Octoprint.
After an army of calibration cubes and Benchy’s, I could finally tune my prints to the best of my ability. I use a .6 nozzle, and I figured the best results are with a .3 layer height and about 70 mm/s (it can depend on a print-by-print basis) for PLA. I also have changed many more settings, which you can find here:

The main issue I ran into was warping on the print bed when printing thinner models, and the way I solved it was by having both a higher bed temperature and a short 1-minute pause before printing after the bed had heated.
I have previous short posts and status updates on the printer projects at my Instagram (here)
