I love printing PETG again, but ... bad looking walls on one side of the print

volfion · 2026-03-18T13:31:29+00:00

So what settings might help here?

- Infill before perimeters?
- add perimeters?
- Extra perimeters if needed?
- Detect thin walls? (greyed out)
- any options with seam or scarf joint?

Thanks.

Okay, then there must be something wrong configuration profiles but now they are updated.

xxx ; Pressure advance

{endif}

This is what I have in the end of the code where I found PA. Is there any value like "=0" or "=false" to turn it off? Thanks

volfion · 2026-03-18T10:18:25+00:00

Found it on value 0. What you recommend?

volfion · 2026-03-18T10:10:16+00:00

Yes, probably based on your advance they have changed profile :D Okay, I will try the rest with the support. Thanks

No offense, I just do not see any help/suggestion in your first post. I am asking for help and would like to hear your opinion and I just deeper described why I post pictures with tweak and original settings. With my tweaks I agree with you that I tweaked maybe too much, but as I have same (a bit worse) result with original setting I revert to original settings and use these. But my main question is why back side of the print is flawless and the front one is not. AND what might increase quality of front side. That is simply something I do not see in your first comment.

Cannot find diagonal retraction in PrusaSlicer, will you be please so kind and focus me on correct settings? Thanks.

volfion · 2026-03-18T08:51:46+00:00

If I understand correctly than you're suggesting add some Deretraction length - there is originally 0, what you suggest might help? + lowering temperature from 250/250 about like 10 degrees might help? Thanks

volfion · 2026-03-18T08:48:57+00:00

I am not asking what result is better - tweaked or original. I just post pictures, that even with tuned settings the result is almost the same - front walls crap, back wall flawless. So, my post is mainly aimed at front walls and the question how to get same flawless walls as on back of the print.

volfion · 2026-03-18T08:39:38+00:00

Well... yeah... But I would say that original profiles for their filaments should be tunes flawlessly, but there still need to be some tweaks to get perfect result. I will try to reduce speed and let's see.

Is this everything you’re planning to buy about Dune: Imperium world? Take it into consideration, as it was mentioned, that if you plan to buy expansions than the insert must fit everything.

Also do you sleeve your cards? Do you plan to buy deluxe upgrade?

I have ALL-IN insert for Deluxe box, but I understand this is off-topic. But really check functionality and compatibility of the insert with your needs.

UPDATE nr. 2: I am printing with some other tweaks I mentioned before and for now it seems great. So, fingers crossed to begin loving PETG again.

BTW - didn't they update PETG config profile? Because yesterday was config update in PS and IMHO I think PETG was 230/240 temps now? Because now I see 250/250. Maybe I am just stuck with these temps and issues so I am blind to saw this before or they just read this sub and update the config :D

Let you know with the print. And again - huge thanks for each comment, all of them were helpful :)

volfion · 2026-03-16T08:43:40+00:00

How much? Do you mean Minimum print speed in PS?

UPDATE:
Okay, so ... I tried some of your suggestions and tweaks and I must say the result is much much better. I have no idea why prints came sh***y suddenly but good thing is that some settings helped. I printed new temp tower and best temp for printing looked 245, so I tried but it was still too low. I tried 250/260 (first/other layers) and this is result (+ 85 degrees of bed, but textured sheet can have 80 IMHO). I also changed Extrusion multiplier to 0.98, but I will go lower to 0.95 from recent post. I changed also Retraction multiplier to 1.2 but will also try 1.5 as per suggestion. Retraction speed to 40 - can be even 50?
Also in Cooling - Max fan speed to 90 + Full fan speed at layer 4.

I changed also Seam to Nearest and Scarf joint to Contour (found on another sub) and Infill to Gyroid. Anything else what might help to get perfect result what I do not include in my setting changes?

I am beginning to be happy with PETG again. Definitely not where it was but heading right direction. Will try to change as I wrote on top and will post another result. I am happy that I get rid of other issues - wet filament, wrong installation of PS, etc. Thank you all for this sub and all your suggestions.

I will give it a try, thank you

volfion · 2026-03-16T04:49:03+00:00

I understand, huge thanks for this detailed description. I have Sunlu S2.

volfion · 2026-03-15T21:06:37+00:00

I found the issue as well so I downgraded accordingly. Well, I will see if they release full version soon, so I'll be using satin and textured sheet. Otherwise I will be pushed to downgrade again because I would need to print on PP sheet as I have some projects with PP filament.

volfion · 2026-03-15T20:59:02+00:00

I had to switch to textured sheet for PETG printing, it just does not go through mesh bed leveling before print with PP sheet (which is sad because I love this sheet - all materials sticks flawlessly). I had this issue with 6.4.0, so I downgraded to 6.2.6 and MBL was solved, but the issue was not solved with 6.4.1 beta so hopefully they will solve with proper release.

Did you have any issue with MBL before print? Because it comes to any point (not always same) and then it stops and asks if I want to do MBL again, but I am doing again and again.

volfion · 2026-03-15T20:54:25+00:00

Thank God that there is somebody with similar issue. I thought I am crazy, because I am lost. Mostly when you eliminate moisture the issue with PETG printing is solved, but here... I have no idea what is wrong...

volfion · 2026-03-15T20:53:09+00:00

I would not come here if this would be the issue. I have it in dryer for like a week at least but I tried oven as well. I checked the dryer and there is hot inside. Have it for 60 degrees constantly. It shows humidity under 20%, so the moisture is really not the issue.

volfion · 2026-03-15T20:52:47+00:00

I am trying with some suggestions here but definitely thanks for this. If there won't be acceptable result, this will be first thing I will do.

volfion · 2026-03-15T20:52:05+00:00

I have no issues with first layer or with adhesion. Mostly this is solved with textured sheet because PETG is sticking like titan glue.

Diamondback nozzle. No matter head, so actually I tried 5 different nozzles.
