SuperSlicer VS OrcaSlicer

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

You might also try a different slicer. I used Qidi Slicer for a couple prints but found better results from Orca Slicer and haven't looked back. You might find that Orca works better for your PETG projects. It also has calibration functions for helping set the flow ratio and pressure advance (https://github.com/SoftFever/OrcaSlicer/wiki/Calibration).

Might be result of https://github.com/SoftFever/OrcaSlicer/pull/2954

Ive never gotten qidi slicer to work that way .. use orca slicer, xsmart3 has a built in profile https://github.com/SoftFever/OrcaSlicer/releases

Not sure which slicer you're using but should definitely switch over to OrcaSlicer for much better print quality. OrcaSlicer

My idea is to not use Cura ;) try this one instead: https://github.com/SoftFever/OrcaSlicer/releases/ It's been working great since the first releases, constantly updated with the latest features from Prusa, BambooLab and self-developed things.

With the new OrcaSlicer 1.7 Beta release which includes K1 Profiles by default I decided to give OrcaSlicer a try.

Calibrate the flow ratio, the default is 0.98, which is a little high for most PLA, and should probably be 0.93-.95. Slight overextrusion results in uneven layers. You can also change the print order to outside-inside-infill, but this can cause issues with overhang quality, and masks the issue by pushing the unevenness to the inside instead of actually fixing it. https://github.com/SoftFever/OrcaSlicer/wiki/Calibration
