Changed to .6mm nozzle and this happened! It was hard to find the right slicer settings. I couldn't find a video or instructions for my printer (Ender 3 S1 Pro). Creality Slicer doesn't even give me an option for another nozzle (see image). Luckily, I looked online at the needed values, and after some initial test prints (like the botched picture where I didn't change the line width), the final prints not only turned out great, but quite solid and they printed very fast! Here are the settings: - Layer Height (set at 50-70% of nozzle size. I used 0.4mm since my nozzle was 0.6mm; see image). - Line Width (Set this to the same as the nozzle [0.6mm] which should change all the child settings; see image). - Speed (I've tried reduced speed, but actually my working tests seemed to print fine at full speed; see image). (Note: you can use the settings search bar in the slicer even if you don't see a particular setting and it will appear or go to Preferences->Settings and select the options you want to show without searching). For a video of the value of changing nozzles (with a link at the end for how to change one - unfortunately not an Ender 3, but it gives you the idea), try this: https://www.youtube.com/watch?v=XvSNQ7rVDio If anyone has better information, feel free to share it and improve my findings. :)
