Need help with bridging settings

[EndlessHunt]

Hi.
In general I'm quite happy with my settings. I'm printing parts for my LDO Voron 2.4R2 300.
I'm using Simplify3D 5.1.2 and are printing the parts on my Anycubic Kobra Go that I'm running on Klipper/Mainsailos.
Basic setting give an acceptable quality at this time considering it is the cheapest little bedslinger I could get.
I'm using eSun ABS+ at 240C on the nozzle and 100C on the bed


And the problem areas - bridging and thin/small areas




I would appreciate any help with bridging as I do not understand the basics of good bridging at this time

Blessings

This looks like it's not detecting at all that those are any bridges and not treating them like that, adjusting bridge flow, speed and cooling. I am not familiar with S3D, can you force it to detect those as bridges? Are you using part cooling fan when printing?

If I may suggest, can you try different slicer? I have good experience with Prusa Slicer, has very usable VORON profiles you can use once you build yours, and I haven't seen it having issues with bridging in that slicer. With Cura you may want to set Experimental Bridging to get results similar to Prusa Slicer. Super Slicer has even some additional setting which allow for truly beautiful bridges but I think at this point you will be happy with anything but this.

Hi Sanity, S3D does detect it. It is the areas coloured yellow in the image below.



I just do not have a clue as what to tell it to do with the bridges. This is my setting at the moment

PS. IT is a open printer so I'm not using any part cooling at the moment

I did figure out that these corners was my pressure advance that was to high



Dialed it down and now it looks better

As always, the Ellis guide is invaluable. It also looks like you're overextruding on the top layer. Even with an open printer, you probably want to add cooling to help those bridges.

Thanx, was slowly getting to the same conclusion.
I need to do a systematic and complete run through/tuning of the printer.
I have never before had to do proper bridging as I always avoided prints with it, or just lived with the bad bridging.
I now want to solve it for my own betterment but do not understand the basics of bridging.
Not just do this or do that but why you need to do it. -- Give a man a fish - or teach him to fish --

Hi, I've switched to SuperSlicer and have been playing with settings.
Improved the bridging but still need to work on overhangs

First layer still need some work done


and got the top layer a lot better as well



Any advice on how to improve tings further would be welcome.
