Yes, I would agree that if you use the Wham Bam, it could be too warm for the Ultimaker / Lulzbot / machines that would have their electronics completely covered up. Wham Bam does offer some printed parts to raise the enclosure up into the air so there is some airflow from below. I encountered some issues with the 3D Print Clean enclosures with my Ultimaker S5's when the lab space got warm in the summer. We added several heat pumps to that lab and now the room stays at 70F and monitor the enclosure temperature to make sure it isn't too warm. (We can increase the air flow to keep things in a safe range)

Gentleman, there are other options for enclosures that are probably less expensive 1) https://ultimate3dprintingstore.com/products/hepa-cover-compatible-ultimaker 2) https://fbrc8.com/products/ultimaker-s3-safety-enclosure-kit 3) https://whambam3d.com/collections/hotbox-for-fdm/products/hotbox-mega-3d-printer-enclosure I've been using the PrintedSolid top/front door enclosure for my Ultimaker 2+ Depending on your budget, you can purchase a BOFA 3D Print air filtration device ($999 or more) or check out the 3D Upfitter Carbon Air Filter ($60) that could fit in the back. Here's how I did it for my UM2+ I don't have the specs for the UM S3 but I suspect it would fit under the WhamBam Hot Box Mega. It fit around the large Lulzbot Taz 6 and even a generic (Eryone) 300 x 300 x 400 3D printer. Add your fire protection device, your air filtration system and off you go.

Hi I've been using 0.8 nozzles for a long time and find 0.25 layer height gives great detail and reduced layer lines, especially on large prints. That means less post processing for me - think sanding, filler, sand, prime. Rinse and repeat. That said, the "Balanced" profiles should be labeled as experimental, which they are. I was hopeful that owning an Ultimaker S5 (well, 7 of them!) would mean that the latest version of Cura would be thoroughly tested on your native machines. Your last few releases have been plagued with bugs that are painfully obvious to your customers and users. Please slow down. Test thoroughly. Gather input. Don't be pressed to release until it's truly ready. (I come from a software dev background, so I know what you're probably up against.) Usually I wouldn't jump in and try a newest version but I did this time. And it set me back a few days and plenty of wasted material. Thanks for listening to my feedback.

Faster isn't always better!

I can't share the part publicly in this forum but I can send you the project file via PM, if that is ok? These prints were done on the Ultimaker S5, Core 0.8 and Tough PLA

Yes, I had tried the "new" balanced "fast" printing setting that clearly the Cura team didn't test adequately. Very frustrating as we have a media event today that is coming to see our fleet of Ultimaker's in action. I'm now re-slicing in 5.3 and re-printing since these newest builds are totally unreliable and untested.

I have prints that keep experiencing pillowing even though they have 5 or 6 top layers On this one, with 20% infill and 6 top layers, this is the result. 0.25mm layer height with a 0.8 core/nozzle Here's the results and my settings...thanks

Cura 5.5 I can't post the data due to security but I just finished a print that used trees supports and adaptive layers. Default settings on the Ultimaker S5 using Tough PLA and the Normal profile (0.15 layer resolution). I noticed with Adaptive Layers checked on, it wanted to go as thin as 0.05 layers and figured it would be an interesting test. Support Z distance was 0.4 and that usually works very well. However, with Adaptive Layers (AL) ticked on, I didn't see where it adhered to that z distance for the support interface. I wondered if anyone else has observed some issues with AL and prints that utilize supports?

Which BASF product? Glass filled? I've printed a few and never messed with standby temps. But I also didn't use Breakaway for supports Let us know!

Is that printed on an Ultimaker machine? I know I have added frequent core cleanings to my routine and amazed what comes out using the cleaning filament sticks from Ultimaker. I find the default profiles for Ultimaker machines tend to work alright. However, on my other machines at work and home, I stick to calibration testing for each material. Temp Tower, Slicer Flow settings and then on the retraction tests just to be sure. I print large, multi-day prints so I try to get it right the first time.

I don't even dare download it since the link "For more information" that came up on Cura links to the June release (https://ultimaker.com/learn/ultimaker-cura-5-4-beta-release-notes/) C'mon guys. Let's get this right.

Yes, this is what many of us have reported. Hopefully they fix this soon. After numerous failures I've had to go back to 5.3.1 until this is sorted out.

I'm trying to say nice things about the new machine but .. I have 7 Ultimaker S5's I purchased for work. The WhamBam bedsurface works great, probably as good or better than the S7. All that wasted space for an air filter is really sad. No increase in print volume. (Our machines sit inside 3D PrintClean enclosures that have fire suppression and air filtration already covered) While I am glad to see they take air quality seriously, doubling the height of the machine without any gains in print volume is disappointing.

Adding addition layers of Skirt Height in 5.4 is the most moronic change I've seen with Cura. And I've been here since 2014!

I'm glad you mentioned this. Recently if I use Cura all day on my Windows 10 laptop, I'll eventually get some serious stutters or a crash stating OpenGL has failed. I try to make sure the bigger resource hogs, like Chrome or other browsers are not running while I am trying to do large print slices. Also, I do not understand why Skirt Height was changed to two? If you can't remove skirt layers at one layer, you're a bit of a dope 😀

Yes, the tree support are way better but without the support brim, it's a bit risky on my bigger models

I have been using the plugins Auto Towers and Parts for Calibration and Cura is completely ignoring the temps I have specified with Post Processing. It seems glued to whatever temperatures are setting within the Materials section. Doing some testing here - so if the first layer of the temp tower needs to be 220C, set Initial / Printing temp to 220 If the end of the temp tower is 190C, make sure the Final Printing Temp is 190C I'm not sure what broke in this version. (But they managed to break support brim too!)

As I mentioned on another thread, I notice the support prime tower brim isn't as wide as I would expect I've had a few failure due to the prime tower getting knocked over (Ultimaker Tough PLA and Ultimaker PVA) Prime Tower Brim in 5.3.1

I'm seeing this too. If you use a prime tower, no real brim is there. I've had 2 prints fail since the prime tower got knocked over. Using Ultimaker default profiles for UM Tough PLA and PVA support.

I'm not sure what causes this but I generally Duplicate a Generic Material (like PLA) to create new entry for the material I am using. Frequently, while filling out the Display Name, Brand and such, Cura will "hang" or pause. Sometimes it comes out of it, allowing me to fill in the information Many times I have to close Material Manager and open it again. Wish List - I have 15 different machines and I would like to see a field for "Machine" in the Material Library. If you have many different machines in your print farm, organizing different materials in the Materials Manager can be quite challenging. Thank!

I've noticed with the newer versions my once perfect z seams are looking worse.

I've noticed this too. I also encounter how Cura text will look jagged and checked my video drivers. I have the latest.

Thank you!

Thank you for this, I had the AA08 in there and it didn't like that. AA04 is in now and working with the AA08 in the other extruder. It is printing very nicely now!

Well, I cleared everything out, restarted and this time I had the ability to Enable the extruder. Something seems wonky there? When I was able to select it, I get a warning about the profile However, it's back...so I'll press on.
