It really just looks like you are over-extruding a bit. Perhaps try live-adjusting your flow rate down a bit?

Yep, so I did manage to get it working! This was my config file: [service_wifi] Type = wifi Name = *SSID name* Passphrase = *my password* EAP = peap Phase2 = MSCHAPV2 Identity = *my username*

And they actually have an example file for eduroam, which is perfect given my university setting. Outstanding.

Oh, that's outstanding. I thought the config file feature in the new firmware would be helpful, but the template didn't have the right fields. I didn't follow the deeper link explaining the full capabilities of Debian. I'll give it a shot and report back. Thanks so much!

Just bumping to see whether anybody has any experience or thoughts on this issue?

This can happen if you have a 'static' infill pattern that slowly builds up excess as layers keep piling on. IME, grid is the worst, because it is a perfect repeat. Cubic is a bit better, because at least the lines offset a bit as z-height increases. But gyroid is really the best at minimising this due to the constantly changing pattern, and highly recommend. You can also set combing to a short distance (maybe 10-30 mm), and set a z-hop during retraction. This way, the print will drop during any large travel moves that are longer than the combing move. Only risks with this are that if you set combing too low you will get excessive retractions, and z-hop has always given me a bit more stringing. [EDIT] Just realised how old this post is *facepalm*

Hi there, Is there any way to connect the S line to WPA2 Enterprise WiFi? That is, WiFi that requires a username and password? Perhaps I'm just missing something, but the option to add a username just doesn't seem available through any of the automatic or manual setup options. Just entering my password without a username fails to connect. But I do know that WiFi works, because I can connect to my WPA2 Personal network at home. If connecting to Enterprise WiFi is not possible, is it an option that can be added? Seems like a pretty big missing feature for larger organisations that doen't just have a simple WiFi setup. [EDIT] Should add, my S3 is running the 6.1.1 firmware. Thanks!

Understood. Although I really must stress how important it is that you try and make 3rd party users feel important, rather than just being relegated to the 1% as suggested by Nallath. Reiterating my personal 3d printing 'journey', I started with an Ender 3, and out of all the slicers I tried, Cura worked the best/easiest. This positive experience with Cura on a 3rd party printer directly lead me to buy an Ultimaker S3. Subsequently, my advice to others built on this experience has directly lead to at least four other S-series purchases. If PrusaSlicer had worked better with my Ender, all those sales would be lost to Prusa.

First reference I could find quickly, on these very forums: https://community.ultimaker.com/topic/14211-cura-faq/ "Which 3rd party printers are supported by Cura? A complete list of supported 3rd party printers can be found here." There are also several notes about not offering technical support for third party printers. I don't think that suggesting the software is 'not broken' really qualifies as technical support, your definition may vary. And look, I appreciate that 3rd party printers might not be the #1 priority on a day-to-day development basis, but consider that Cura is the gatweay drug into the Ultimaker ecosystem. You must surely gain a huge portion of your sales from 3rd party people starting with cheap knockoff printers, using Cura, then specifically selecting an Ultimaker printer as their next step up because of their familiarity with Cura. That is certainly why I bought my Ultimaker printer, and why I have convinced many others to buy Ultimaker printers. That all goes away if 3rd party support is pushed too far to the background.

Fair call, that was completely unnecessary and I apologise. You should talk to your marketing guys, because 'support' is explicitly used in relation to third party printers. Marketing again. The 'Easy to Use' tagline doesn't really jive with expecting people to jump on Github or install Beta versions. In any case, thanks for the fix. I'll upgrade when the fix makes it to the production version.

I'm the same, I had configuration files from 4.4, 4.5 and 4.6 on this PC. It is easy to try it for yourself. Move all of the folders from "C:\Users\*your username*\AppData\Roaming\cura" to a temporary directory. Restart Cura 4.7. When I did this, it ran fine. But if I restored from backup, it would start crashing again. If I deleted the 4.7 profile data, put the old profile data back, then restarted 4.7, crashing again. Something in 4.7 is terribly broken when it tries to use the old profiles. So, I figure choices are stay with 4.6 for now and wait until 4.7 is fixed, or rebuild all your profiles. [EDIT] I should say, everything works fine for my Ultimaker S3. It only crashes when I select my Ender 3 as the printer.

I think the problem is that every time Cura 4.7 restarts, it re-grabs the profile data from 4.6 or earlier versions. You have to delete *all* your profile data from previous versions before restarting Cura 4.7, and only then will 4.7 run properly. Needless to say, losing all my carefully curated profiles is *completely* unacceptable, and I have dropped back to 4.6.2 until Ultimaker gets their crap together and fixes this ridiculous problem.

Just another update on this...... I'm going through lots of different print settings, learning the new machine, trying to optimise speed vs print quality. One thing that was really confusing me was that Cura was setting the line width so narrow in the default profiles. For example, the Generic CPE profile I started with for AA 0.4 print core has line widths set at 0.35mm for outer walls and top/bottom, and 0.3mm for inner walls. Cura, and all other advice, has always set the line width as equal to or greater than the nozzle size. So I just started a print with all line widths set to 0.4, matching the nozzle size, and the first layer finish is VASTLY improved, both in terms of feel and visibility. It is definitely still smooshed down. Now, I'm sure this has been done to death at some point in the history of these good forums. But is there a good reason why the default Cura profiles for Ultimaker printers use such incredibly narrow line widths?

Just as a point of comparison, I printed the same STL using my Ender 3, eSUN PLA+, a CURA profile matched as closely as possible, on a battered and bruised magnetic sheet bed. The results from the Ender are baby-bum-smooth in comparison. You can still feel the slight roughness on the edges of each line, but it has none of the extreme banding and up-and-down undulation perpendicular to the lines. I am sure there is something fishy with the results from the S3.

Thanks for the feedback. I'm genuinely surprised that this might be normal. Running fingers over it, there really is a *lot* of height variation, and I find it so odd that the effect is so localised, so well patterned, and so consistent between prints. After months cutting my teeth on an Ender 3, I've never seen anything like this, unless I had something very wrong - plate height completely, poorly calibrated flow, gross over-extrusion, that sort of thing. I do use glue stick, but I dissolve it in a spritz of DDH2O then smooth it down with Kimwipes to get a super-thin super-flat layer of residual glue. Glass plate was freshly cleaned with DDH2O then 99.9% isopropanol before both prints. Maybe I'm TOO GOOD at 3D printing, and don't know anything other than perfection? Yeah, I don't think this is the problem either......
