SuperSlicer VS prusaslicer-elegoo-profiles

I Would look into using SuperSlicer, a fork of PrusaSlicer

I suggest you temporarily (at least) use some print settings that are already excellent, start of with these). You need to install the official release of Superslicer. Find instructions on how to import the config bundle here.

Well, I doubt it's possible right now since the last release is already a few months old: Releases · supermerill/SuperSlicer (github.com)

There is a known issue where the config.ini contains the wrong version and Arachne is not visible. Check Issue 3094

I must have mis-remembered something, I thought there were a portable and installer version, however on the github download site the latest release, https://github.com/supermerill/SuperSlicer/releases/tag/2.4.58.5, only have one file for Windows which doesn't have an installer, this is the version i already use.

If you're a more advanced user then Super Slicer: https://github.com/supermerill/SuperSlicer/releases/tag/2.4.58.5

I'm not sure about specific settings, but I do have a slicer recommendation. SuperSlicer. It's a modified branch of PrusaSlicer that's basically just a better version of it

SuperSlicer

http://retractioncalibration.com/ I found this super helpful for tuning retractions and in case you don't already have it here's profiles for PrusaSlicer and SuperSlicer I would recommend going with SuperSlicer 2.4.58.2 "fishy" it has a slightly higher better interface and built-in calibrations and a few extra features that PS doesn't have like advanced purge settings where you can set your pigment % for each filament color and it will purge more or less to the wipe tower depending on the pigment change so when you switch to something like white from a darker color it will add additional purge to get a cleaner color. Did you change out the small piece of ptfe in the heatbreak with Capricorn? Since you are doing petg that would probably be a good idea.

I switched to PrusaSlicer this morning. I uploaded the profiles from (https://github.com/andrewsuzuki/prusaslicer-elegoo-profiles/blob/main/README.org)

https://github.com/andrewsuzuki/prusaslicer-elegoo-profiles also have you tried washing your build plate with hot soapy water?

If you're going to run Cura I would advise going to the last stable version 4.13 instead of 5, there's still bugs in 5 that need to be worked out and it doesn't have full support for all the plugins yet, also here's the cura profiles for Neptune . As far as PrusaSlicer I would recommend the SuperSlicer variation, it has a better interface imo as well as built in calibrations and several other settings and features that PrusaSlicer doesn't have, here are the printer profiles that work with either prusa or super. Marlin adds more adjustment options from the printer menu, it enables curved printing lines instead of many short straight lines (called arcwelding), enables manual filament change scripts, implements abl in a better way, communicates with octoprint much better, allows baby stepping for z height adjustments, etc.

I highly recommend using SuperSlicer 2.4.58.2 'fishy' build for the 2D, it has the multicolor painting features from PrusaSlicer 2.4 but has the slightly better interface and the built-in calibrations and other community driven improvements that SS has over PS, and add these profiles . That's basically all I use for my 2D now, if you want to be able to use Cura 4.13 for lightning infill or tree supports here's the profiles, it works decent but the multicolor/ multimaterial functionality is highly lacking and very basic.

https://github.com/Toylerrr/ELEGOO_Neptune2_Cura there are modified chep profiles in the readme, Cura 5.1 is supposed to have the Neptune natively, also 5.0 is still buggy and has very limited plugin support, I would skip it and stick to 4.13 or skip cura all together and get SuperSlicer and use this https://github.com/andrewsuzuki/prusaslicer-elegoo-profiles

Theoretically if everything is tuned properly you shouldn't need z-lift, I like to have it on as extra insurance that the nozzle isn't going to drag across the print and leave scars or knock something loose, it does add a small amount of time to the print but it's usually not that significant especially if you keep the height low. If you go into your settings folder for PrusaSlicer c:\users\appdata\roaming\PrusaSlicer\ you can copy your settings .ini files to the corresponding folders for SuperSlicer and everything so pretty much transfer straight over. Also https://github.com/andrewsuzuki/prusaslicer-elegoo-profiles there's this if you haven't done much calibrations or custom profiles and want a good base to start from.
