Hi, I've good results using Ultimaker TPU (on an UM3, original feeders) and standard settings. Although it's a little bit stringy (especially at inner walls), the printing results are acceptable. So you could try duplicating the TPU profile and eventually change the temperature settings in that new profile. Regards

That's a nice solution.

Hi Carla, I guess it's because the printer itself only knows the "standard" (generic) generic material, but not your eSUN generic. So I fear there are only two possibilities: either use eSUN inside "standard" generic, or always override. Regards

Dem stimme ich absolut zu, denn Messing ist (relativ) weich, und warmes (bzw. heißes) Messing ist noch weicher. Grüße

Hi, if you want to print a model with extruder 2 instead of extruder 1 (or vice versa), just select it in Cura and klick the desired extruder in the left side bar or in the context menu. If you want to switch the extruders while printing one object, using dual color / dual material: you have to split the object into two different objects in your design software, load and joyn both objects in Cura and select a specific extruder for each split, as described in the attached manual: Cura print guide - Printing with two colors.pdf Regards

Hallo zusammen, ich halte mich normalerweise an die Empfehlungen von Ultimaker (z.B. hier: https://support.ultimaker.com/hc/en-us/articles/360011597519-Cleaning-the-Ultimaker-3 ) Ist schnell gemacht (evtl. sogar unmittelbar nach einem Druck, solange die Düse noch heiß ist) und schont das Material. Grüße

Hi, although I was not forced to change the print head bearings yet, a good tutorial for disassembling and reassembling the print head can be found on youtube, provided by @fbrc8-erin: https://www.youtube.com/watch?v=Qf-X8F_9zg0&list=UURBgc5zvVEBMU9o7YjCzFYA&index=2 and here's a good source for small repairs of all kind: https://ultimakernasupport.zendesk.com/hc/en-us Regards

As far as I know, there is no possibility to repair the printcore. You have to replace it. Regards

Hi Multiholle, I fear your project is only possible with a dual (or multi) extrusion printer, because fdm printing works building layer-by-layer. Printing on top of curved surfaces is (actually yet) impossible. But: your design is exactly what you need to make a dual material print (in Cura: load both files, merge files and connect each file with another extruder).Cura print guide - Printing with two colors.pdf Regards

Hi Juliareed, that's the prime tower, that's normally used only for dual extrusion (helps cleaning the nozzles and keep the "wrong" filament out of the print). It can be controlled in Cura, custom settings, submenu "Dual Extrusion", "Enable Prime Tower". Regards

Hi, one more possible issue could be electric interference, as for example mentioned here: https://community.ultimaker.com/topic/30841-interference-on-conductive-sensor/?tab=comments#comment-254894 The conductive sensor is very sensitive, and thus prone to be confused by external disturbance, so it's wort to take a look. Regards

Great work.

Hallo Reab, eine schnelle Möglichkeit, den Elefantenfuß zu reduzieren (oder sogar ganz zu vermeiden), ist, in Cura entweder den Wert "Horizontale Erweiterung erste Schicht" auf einen negativen Wert zwischen -0,2 und -0,4mm zu setzen (Danke für den Tip, @Smithy), ODER mit Brim drucken und das neue Feature in Cura 4.5 "Abstand zum Brim-Element" zu nutzen und auf einen Wert zwischen 0,2 und 0,4mm zu setzen. Der Brim verhindert dann das Breiterwerten an der Basis und löst sich anschließend fast wie von selbst vom Bauteil. Grüße

Hi Jason, afaik this is intended behavior since Cura 4.4 (?). The build material creates a continuous tower, ensuring proper layer to layer adhesion, and the support material is placed at the inner side, and only when the second extruder needs to be primed (for saving support material). So there is nothing to be fixed. With my UM3, I never had an issue with the prime tower, so I suppose with your Mark2 it will also work properly. Regards

Hallo Steffi, ich kann mich meinen beiden Vorrednern nur anschließen und ergänzen: genau für diesen Zweck liegt dem UM3 auch ein zweiter AA Core bei (der im Übrigen auch bereits für Schacht 2 im Druckkopf kalibriert ist). Zur genauen Vorgehensweise beim Zweifarbdruck siehe die angehängte Cura-Anleitung (ist zwar schon etwas älter, gilt aber nach wie vor). Grüße Cura print guide - Printing with two colors.pdf

Olá, por favor escreva em inglês no fórum geral, então a chance de respostas é muito melhor (traduzido do alemão para o português com "DeepL"). Você também usou o BB-Core na Extrusora 2? Com o AA-Core Cura recusa-se a processar o PVA. O material de impressão é então também marcado a vermelho em Cura (o BB-Core é especialmente concebido para PVA) Saudações (Hi, please write in English in the general forum, then the chance for answers is much better (translated from German to Portuguese with "DeepL"). Did you also use the BB-Core in Extruder 2? With the AA-Core Cura refuses to process PVA. The print material is then also marked red in Cura (the BB-Core is especially designed for PVA) Regards)

Hi, first, it would be good to know which printer you have. There are some posts relating to auto leveling problems with the UM3, but they may also be valid for the S5, for example: or So, checking the cables of the capacitive sensor would be a good first step. I also heard that fan cables running across the capacitive sensor or pinched cables can cause trouble, so its worth checking. Regards

Yes, you can uninstall 4.4.1 (check first, if 4.5 works), but DON'T remove configutation files / settings (I made this mistake once and hopefully never do it again ;-) ).

Hi Jockcraw, I don't know which printer you use, but relating to Cura preview for an UM3, the design itself definitely should be printable, even with standard .4 nozzle and 2.0 (and better) layer hight. Perhaps your printer and/or Cura settings are not optimal (but I guess Smithy can help you when he sees the photos). Regards

Hi, if you want to do it right, you should use the ultimaker-recommended procedure for calibrating the print head, as described for the UM3 here: https://ultimaker.com/en/resources/50679-check-for-play-on-axles The procedure for the S-line is the same, only the calibrating sticks are different (@NovaStarGX has already posted the right source). Regards

Hi Corey, if the belt is not worn out to much, it possibly could be tensioned very easily, as described in this video by @fbrc8-erin: As the sliding blocks (which contain a build in tensioning spring) at the UM2, UM3 and S-Series are the same, this procedure might work for your UM2 as well. It would be also a good idea to check the play on the axles and -if needed- calibrate the print head as described here: https://ultimaker.com/en/resources/50679-check-for-play-on-axles Regards

Hi, there's a helpful tutorial in this forum: https://community.ultimaker.com/files/file/1650-filament-verbinden-filament-splicing-tutorial/ Just using a lighter seems not to work very well, using a hot (preferably flat) soldering iron works better. Very important (and a bit tricky) is to remove the burr and ensure the filament is not to thick to enter the extruder. Regards

Hi minuteman, afaik you can keep your version 14.07 and install the acutal version besides it, so you could test the new version and if it works, just uninstall (or keep) the old version; if it doesn't: just use 14.07. Regards

Hat schonmal jemand die Funktion "inaktive Düse abstreifen" beim Einzugsturm ausprobiert? Klingt so, als wäre die genau für das von Euch beschriebene Problem gedacht. Vielleicht hilfts. Grüße

Hallo Roland, das schreit ja schon förmlich nach einem Einzugsturm (kleines Türmchen, das in einer Ecke des Druckbetts gedruckt wird und die Düsen bei Dualdruck vor Erreichen des Bauteils abstreift) oder zumindest einem Sickerschutz ("Hülle" um das Bauteil, das den gleichen Effekt erzielen soll) oder, falls Du Cura in englisch benutzt: prime tower oder ooze shield (befindet sich beides in der Rubrik Duale Extrusion), damit die Stütmaterial-Reste am Türmchen, und nicht am Bauteil abgestreift werden. Der Einzugsturm ist im Cura-Profil für den UM3 standardmäßig aktiviert, beim S5 aber scheinbar standardmäßig deaktiviert (aus welchen Gründen auch immer). Hoffe, ich konnte helfen. Grüße
