Sadly...that didn't work, but I got a slightly...very slightly...improved print by turning off "Retract at layer change" and "Retract before outer wall". It didn't completely fix it, but it's slightly better. I'm just screwed at this point. I'm a month behind on a project and the owner is likely going to yank this from me.

Ok...I'm about to just give up. After going to the base profile, and adjusting temps, I got better prints but not perfect as I was before. Using Slashee_the_Cow's suggestions did not make much of a difference, but someone else that also was helping me did...however, on "taller" prints, I'm AGAIN getting separation lines. Out of curiosity, I switched the following Z-Seam setting... Sharpest Corner - Smart Hiding to Sharpest Corner - Hide Seam...it did not change anything (this is good because before one or the other would basically make things MUCH worse). Now...interestingly, this separation line, is right at the top layer of the detail behind the perimeter as shown in the 2nd picture. What could be causing that? Any more thoughts on this? I'm well past a deadline now and everyone including myself isn't happy...all due to a frigging firmware update.

Awesome thank you!

Enable Coasting - Is off already Combing Mode - Already set as Not in Skin Printing Temperature - Did a temp tower when I first got the printers, with eSun it was good between 200-210 which I was printing 205. Now with the new firmware on the printers, I did another one, and 195-205 was good. Replicated those same results on another S1 so I stuck with 200 for the temp as it was in the middle and there was almost zero difference between 195/205 so 200 felt good for a margin of difference either way. Outer Wall Wipe Distance - Was set at 0...I will try another print later with 1 just to see. Top Surface Skin Layers - As mentioned, I was doing 0, tried 1, didn't make much of a difference at all...but willing to try 2 for giggles on a cut down test portion of the same file so I'm not wasting more filament (I'm at 6 rolls wasted at this point). Top Surface Skin Line Width - Default is 0.4, but I could probably knock that down to 0.2 as I'm using a 0.4mm nozzle...right? Speed - Default was 50, I was printing at 60 prior to all these issues, but I can easily try a 50 and/or a 55.

This is the issue I need some recommendations for. I have 200 temp, 0.8 retraction at 45mm with eSun Grey filament (tried 205 and 210 but no change). I'm still getting "cotton" like stringing. Any thoughts? Default was 5mm which I am of the understanding is nuts for the S1. 0.8 is what I was running previously and only had a little stringing.

SUCCESS!!! At least like 95% anyways... So I've gotten majorly frustrated with this issue...been going on since August 10th roughly. I decided to go back to basics. As such, I wiped my profiles in Cura 4.13.1, and copied over BASE profile settings from Creality Cura 4.8.2. Edited little things, like temp, speed, retraction...and started printing. Below are pics of a successful print on Cura 4.13.1...but there's an issue I cannot resolve & 1 I'd like recommendations for. I have top layer issues in the below pics. This is not replicating on the TOP most part of the print except in 1 picture. This is just above what could be considered a door on one side and a simple detail outcropping on the other side. It's as if the top layer just isn't printing. I went from 0.8 for Top/Bottom Thickness with 4 layers, which was the default in 4.8.2...to 1.2 Top/Bottom Thickness with 6 layers...and both were about the same results. I even tried changing from 0 to 1 for Top Surface Skin Layers...and that didn't really do much of anything either. Issue is in the red "boxed" areas in the below pictures. I'm currently printing one with 1 Top Surface Skin Layer and 1 for Top/Bottom Thickness with 5 layers. I'll post pics when it's done in the morning.

Now attached is an original Gcode file that printed just fine before the firmware update B1-1.03e.gcode

Surface only print done, oddly it did not print the top section of the print, that was spaghetti in the open area when I woke up this morning. I don't know if it's supposed to look like this or not, but it is what it is, and yeah I see there was some lifting from the bed on one corner but I expected that since it's just printing 1 wall it seems...

I have a Gcode file from before the firmware update which was printing perfectly, but not a *3mf file...would that help at all? They were done on Creality Cura 4.8 (4.8.2 if I recall correctly).

What version of Cura would you like the *3mf file in...or does that not matter? As for the firmware / version of Cura...yep, they are all printed on the new firmware, and I can replicate the results on my other S1 printer as well...so something has definitely changed, and I cannot get my previous printing ability back by rolling back on firmware version...as I've tried a few times. I wish I could, I'd just roll back and keep on keepin' on with what was working.

Ah ok...should I try a "Surface" print or no? As for Coasting, it is off...I don't have anything selected in experimental.

Yeah...super odd. I've even tried (today in fact) to adjust the flow in Cura and that's not helping either. Still getting the exact same results. As for the current setting...I'm unsure. It's a stock Creality mainboard for the S1 (standard version, not the pro). Here's the link to the Firmware. https://github.com/mriscoc/Ender3V2S1/releases/tag/20230805 I was using a previous version & everything was just fine. The specific file I'm using is the Ender3S1-F4-20230809.bin version...so no linear advance, no UBL, just nothing special. I specifically have been choosing the most basic version just to avoid all this! LOL What's "Surface" mode?

Yeah...I did that, still not getting emails even though I have it set to email me when new replies come in...but thank you!

Also...is there any way to force this forum to send me a notice I have a reply? I'm subscribed to this thread. I've even unsubscribed and re-subscribed and I'm not getting emails. They aren't in my spam folder either.

Also...just for giggles, I tried Prusaslicer (I know it's a dirty word here), but I needed something else to try, and with barely any changes to the base profile, this was the results which is darn near perfect... I don't want to use Prusa, I want to use Cura, but this just isn't making sense to me
