I am currently experimenting again with the tree supports. The post mentions that the horizontal expansion has been added here as a new setting. However, as in the alpha, this does not seem to be adjustable when using the tree supports. However, the value that can be entered when switching to normal supports is not accepted here either. this means that no horizontal expansion can be set for the interface layers. unfortunately, i cannot use the tree supports for larger and flat support surfaces, at least in this way.

Ah, missed the link and clicked the "react to post" button instead. Gonna try again

How about a little download link to the beta so that we can try it out right away? 😉

I had a similar problem. It's been a while, but the noise sounds very familiar. One of the bearings in the print head was defective. The rattling came from the balls in the bearing. It was probably because they were no longer running smoothly and were constantly bumping against each other. The noise could be reproduced when the printer was switched off and the printhead was moved by hand along one of the axes. After replacing it, everything went back to normal. I would check this quickly because shortly after the noise started, the bearing jammed completely and the printer would no longer print.

Oops, a mistake on my part then. I have only ever cleaned the extruder housings and not changed them. I thought until now that the extruder gear sat directly on the motor shaft and was not changed when the extruder housing was upgraded.

It is important that the gear on the extruder motor has also been changed. Only the extruder housing will not be sufficient. In addition, the CC Printcore is not compatible with the UM3 as standard. You would have to find a way to adapt the configuration file. I believe that otherwise the UM3 will not accept the CC Printcore.

You have to set the setting "Top Surface Skin Layers" to atleast 1. You can't change the print settings of layers which are not printed. It's like saying "i want my spoiler on my car blue, but i dont't want a spoiler".

We have also had this error several times now. We were able to find out that it is not a connection problem. For us, the error occurs when the print bed temperature is too low (below 60°C). Apparently the fan has its own monitoring. If it cannot measure the speed of the fan even for a short time, the printer stops printing immediately without being able to continue. We wrote this to Ultimaker support a month ago. So far, they have been able to reproduce the error once on a printer. However, we have not heard anything further from support. The error no longer occurs when the filter is removed from the Airmanager. Apparently, the air flow is significantly lower with the filter and thus triggers the fan monitoring much faster. In fact, we have disconnected our Airmanager from the printer for the time being because we have a few jobs to process and the Airmanager is not contributing to the reliability of the system at all. As long as Ultimaker finds it necessary to let the firmware cancel the print job completely when this error occurs, I cannot recommend the Airmanager.

We have finally found the reason why the S5 Probundle occasionally stops printing without error. In the case of the observed print abort, the print head stops abruptly and the print bed moves downwards. No other functions are triggered! No retraction of the filament, no pause function and therefore no possibility to continue printing. While we were able to observe an error message on the display with previous Air Manager discontinuations, there were now several cases where the display remained completely black and thus no error message was available. With such interruptions, we rather suspected the material station as the cause. Now, however, we can say with great certainty that it is due to the Air Manager. At temperatures of 45°C or lower, the fan seems to run so slowly that the monitoring of whether the fan is running tends to drop out. Unfortunately, the firmware seems to have the questionable setting of immediately cancelling the printout without the possibility of a continuation when a short interruption of the fan is measured. Since all materials have been printed on the print bed at temperatures above 45°C, this was hardly noticeable. Now, however, the Ultimaker Nylon is set to 40°C as standard. This resulted in an increased number of aborts and some wasted filament. I would clearly call this a bug. The fact that the print is interrupted should also be improved. At least the fact that aborts cannot be resumed for the reason described seems unnecessary, as aborts can also be continued with other errors.

Für Materialien, die sehr stark auf dem Glas haften am besten den Klebestift benutzen, also UHU oder ähnliches. Wird zum Beispiel stark bei Tough PLA empfohlen. Ich selber benutze ebenfalls die Filafarm Wechselplatten, habe aber entsprechende Erfahrung mit den Glasplatten vorher gemacht. Mit dem UHU Klebestift bekommt man solche Drucke nach Abkühlen sehr einfach von der Platte. Eventuell mit etwas Wasser am Bauteilrand nachhelfen, dass wars.

Does anyone know which settings I can use to ensure that no additional blobs are printed in printed text? In the example shown, sharp corners in the "W" and other letters are displayed with additional blobs. When I print prototypes in PLA, these do not bother me much. But here the whole thing is to be printed in TPU. These additional blobs are very noticeable and lead to extrusion problems due to additional retractions. In fact, the text would be even more covered with these blobs, but by switching off "Print thin walls" most of them are already filtered out here. I have already experimented with different settings and values but have not yet managed to get the text to print without extra spots.

The problem here is that with such a thin layer height and such a small object, very little material is conveyed. PVA is a material that does not like very slow extrusion rates. Therefore, with small objects at this layer height, problems will arise very quickly. Here it can help to set the horizontal expansion much higher, simply to keep the nozzle busy for longer. We have four Ultimaker printers running and print mostly with PVA support. I can only strongly recommend replacing the Ultimaker PVA. Of the many alternatives on the market, Ultimaker PVA is the clear winner in terms of clean dissolving. By this I mean that the water does not become cloudy when dissolving. This makes it easy to see how far the supports have dissolved. In all other categories, the Ultimaker PVA scores rather mediocre to partly poor. By far the best PVA to print is BASF's BVOH. There are virtually no extrusion problems here, so that it is also possible to print with the fine profile.

if you are sure that there are no actual problems with the filament feed (such as a partially encrusted nozzle, filament residue on the feed gear, etc.) the fastest way to print without problems for the time being would be to switch off the flow sensor in the settings. this can be done directly on the printer. in this case, no firmware installation would be necessary and the printer would be ready for use again in a few minutes.

After the digital factory failure about 24 hours ago, i was able to reconnect all my printers to the digital factory, except for one of the S3s. After disconnecting from the DF, I wanted to display a connection code again, but the printer jumps directly into the field with "The printer is now connected to the Digital Factory". Despite resetting the printer's Digital Factory settings several times and resetting it to factory settings, the printer does not display a connection code and immediately thinks it is connected to the DF. As I have also disconnected the printer on the DF website, I now have no way of accessing the printer via the cloud. As this printer is in the printer farm and gets its jobs via the cloud, it is currently down. Any ideas on how to re-integrate it into DF?

I found this can happen to me with the following things: -Special characters within the print job name -Multiple instances of cura open (make sure it's only one) -Log out your account from cura and log in again -I had multiple print job upload errors with the 5.2 beta (5.1 and 5.0 were fine) -When printing over the cloud, make sure the printer has the little cloud symbol active. Sometimes it can bug out yet its visible in the factory. A resets and reconnect to the cloud can help.

Thank you for all the helpful advice. I appreciate it very much. Playing around with the adaptive layer heights does provide "fixed" support interface layers in some cases, but unfortunately not in all places. It kind of feels like I have to work around a bug in cura all the time, which just feels frustrating after several tries. I have looked at previous cura versions and found that this bug originated with cura 15.1 and the new support structures. Along with the change in the order in which the outer layers are printed, I am constantly having to adjust settings on otherwise very suitable profiles for my S5 Pro bundles. Interestingly, this order has been reversed for the metal filaments from BASF, which are now being heavily polished... Long story short, I think I will go back to cura 4.13.1 for the time being. The Cura 5 versions just don't feel smooth yet.

@GregValiant awesome catch! how do you find out about something like that? Unfortunately, I have another challenge... the gaps in the support interface still occur on the first level after the mounting groove as well as on the incline around the screw hole 😅

@GregValiant of course! the print settings for the object can be generic or customised here, the problem with the support interface layers exists regardless of any settings. ArmV7.3mf

Unfortunately, the bug regarding the support interface layers still seems to exist. There are still several places where the outermost layer is sporadically not supported. the strange thing is, i haven't seen another thread about this yet. you would think that this problem regarding support generation with a dual extruder printer would be reported more often... I have taken more pictures of this. I will also attach them to the github thread I created for this. Bad generated support structure · Issue #12839 · Ultimaker/Cura · GitHub

255°C is quite a lot for petg. If I am still printing PETG, then it is more likely to be at 230-235°C. This definitely reduces stringing. PETG also absorbs a lot of moisture from the air, so I would also recommend drying the roll at about 60°C for 4 hours before printing and storing it in an airtight box.

With Cura 5.1 I have noticed poorly generated supports on all my PVA supported prints. PVA parts are printed in the air and the support interface has several gaps in the top layers. I have already reported this as a bug on github, but haven't seen anyone else experiencing this problem yet. You would think that this problem would be noticed more often with a printer that is designed for PVA printing, among other things. Bad generated support structure · Issue #12839 · Ultimaker/Cura (github.com) So I just wanted to ask if anyone else has noticed this problem. Unfortunately, this problem means I can't do anything with 5.1, while 5.0 still has some bugs...

Ich kann diese Meinung über igo3d mittlerweile aber auch langsam unterstützen. Wir haben mittlerweile für recht beachtliche Summen bei denen eingekauft, dennoch bleiben Rückmeldungen und Bestellungen teileweise auf der Strecke. Bei Lagerbestellungen muss nach 1 1/2 Wochen nachgefragt werden wo diese bleiben, Gespräche über Testdrucke und neue Geräte in 4 stelliger Höhe bleiben plötzlich stumm. 3Dmensionals war mir bei ein paar dringenden Lieferungen in jüngster Vergangenheit positiv aufgefallen. Ich konnte direkt einen Ansprechpartner erreichen und alle bisherigen Teile/Filamente/Zubehör und Drucker auch bei denen finden.

the problem with pva in the material station is actually a long-standing problem. However, I would not say that ultimaker is ignoring it. The progress, on the other hand, could be communicated faster and better, in my opinion. Ultimaker has already adjusted the gears on the extruder to cause less breakage. i have also read that they are trying to adjust the pva formula. However, I have to agree that the problem with ultimaker's own pva still exists, at least partially. i have since switched to other pva or bvoh. these materials are easier to print and have never broken in the station. if i were ultimaker, i would use the bvoh from basf as my internal support material and all problems regarding the support material would be solved.

And here I am, almost completely convinced by the material station. In fact, I plan to equip more S5 printers with the material station in the future. when printing small parts in different versions one after the other, the lining up of print jobs works very well for me. of course there is a small delay due to the cooling of the print heads and the clean extraction of the material, but the new job then starts to heat up and print directly without having to feed filament through the nozzle again. When printing several versions of an object, I usually print several versions at the same time to avoid further delays and to have several versions to test.
