  3. In my experience, there are a lot of things that influence accuracy: temperature, speed, flowrate, material, even color (some colors melt better than others, not sure why, maybe due to fillers?), etc. Further there are things like layer-lines (curved edges), blobs, ringing, thickening of corners due to nozzle slowing down,... All these have an effect. The only way to know, is test. Make your typical features in real size in a small test model, and try that. For me, I usually take 0.1 to 0.5mm extra, depending on how tight a fit I want, and whether it are inner openings or outer sid
  4. What is involved with the debinding and sintering? Is there additional equipment required?
  5. I posted a reply to someone asking about longer-term reliability here. SandervG was kind enough to provide some thoughts on my issues and suggested a new thread if I had further comments or concerns. This is that thread. From my prior reply, I experienced a flood of the print head back in early-March of 2020. The print head was shipped to Ultimaker and they "bent it back into shape" per the Local Tech. I've had issues since that time, but the most recent issues have been communication error with the print cores (ER34), flow sensor issue (ER65), and I2C communication error (ER35). B
  6. I am still using Cura 4.2.1 because I had no disconnections over ethernet on my S5. Also I haven't upgraded the FW, still 5.2.11. But I was thinking of an upgrade. In my case disconnections were linked to the creation of a bunch of "shadow" printers by Cura 4.3, 4.4 and 4.5 (all were a PITA regarding this weird behavior). Printer were visible in the printer management tool, but not connected except one. That was messing up the connection. Is that your case? I had some calls with Ultimaker Team, but they were saying not to be able to reproduce the problem....
  7. Hi, I’m printing a huge model for a client in PLA. It will imbed metal parts and components that must fit accurately with some tolerancing. My first sample test part I printed at 0.1 mm resolution and that wasn’t accurate enough to fit the small metal parts. But it worked well at 0.06mm. However to print the full complete product at 0.06 mm will take 6 days!! That’s too long, and there’s risk for an error in the print. Only alternative is to print at a lower resolution and expand these features. But by how much? It must fit metal discs that are about 0.08” A
  8. Oh man ... das war es! Danke! Auf dem Karton steht DDE ... wie ich dann auf DDG komme ist nicht zu erklären. Sorry! ABER, was mich irritiert: Ich bin dem QR-Code auf der Bondtech Karte gefolgt die zur Anleitung führt. Dort stehen die 311 drin. Ein Fehler von Bondtech? Die Montage ist auf jeden fall die selbe. 😉
  9. What I've done is to set the stepper time out to 4 hours instead of the default 2 minutes when the app is started. I'm not real happy with that as keeping the steppers energized and holding position does involve wear and tear. I haven't found (and I'm 95% sure it doesn't exist) a way to query the machine to find out if the steppers are enabled or disabled. If they are disabled then sending an M114 is useless since as you say - the machine would send back "where it thought it was". If however the steppers are still enabled, then the M114 returns good information on the print head and extrud
  10. Oder die Cura.log Datei hier teilen. Wenn es was eindeutiges ist könnten es normal sterbliche evtl. auch lesen Gruß
  11. Hallo, Stimmt wenn man die Linienbreite auf 0.6 setzt, trieft das meist zu. Zwei wände sind aber für mich eindeutig etwas breiter (eine außen Wand, und eine innen Wand) hier versucht Cura dies immer noch mit Zickzack zu füllen Ja stimme ich dir zu Ich zeichne meist alles selbst neu was ich ausdrucke, und da nehme ich einfach schon auf alles Rücksicht das wo man einfach vermeiden kann. Manche Sachen könnten man (in meiner Vorstellung, bin kein Entwickler) auch anders handhaben, also beim Slicen. In Simplify3d ist es z.B. so das man bei
  12. I do print PP (ultimaker brand) on our S5. It is easy to print; the bed plate adhesion is tricky so it is better to use packaging tape. Also the dimensions would be smaller than CAD model since PP has a high shrink factor. As for the layer adhesion it never been an issue, in fact it is the most impact resistant material I've printed. You can litterally throw your part as hard as you can it it won't break.
  13. Liebes Forenteam, wir haben einen Ultimaker 2+ und waren bis dato auch immer zufrieden. HOT-END Lüfter DEFEKT Nach enormen Problemen mit UNDEREXTRUSION haben wir bei selbigen feststellen können, das der Hot-End Lüfter defekt war und entsprechend zu einem HEAT CREEP geführt hatte. In folge dessen haben wir den HOT-End Lüfter getauscht. Folgende Daten in Bezug auf den Hot-End Lüfter: HOT-End Lüfter ORIGINAL: - SUNON MagLev - MC25060V1-000U-A99 - DC5V 0,58W - C7C10T Austausch-Lüfter: - SUNON MagLev - MF25060V1-100
  14. Hi, I have an Ultimaker 2+ with the below Cura settings: X (width): 223 mm Y (Depth): 223 mm Z (Height): 205 mm I'm trying to print multiple parts and want to maximise the area. I'm printing without any adhesion (brim, skirt etc) and support. Cura is showing that all parts are within the printable area, but when I try to print it from the SD-card I get the error "Trying to print outside printable area". This happens also if I manually move the parts "well within" the boundaries in Cura. How can I ensure that Cura is using the same boundari
  15. I think CPE is very similar to PET? Anyway, PET feels totally different from waxy and floppy materials like PP and PE. It can flex a little bit, but definitely not like PP or PE, only rather like ABS. If overloaded it will very suddenly break without warning, almost like plexiglass. I have no experience with printing PP and PE, but I guess also a 3D-printed PP-model would probably feel different from an injection moulded one, due to the layer lines and poorer layer bonding? If I had to do it, I would probably go for what prints the best, the most accurate. And then post
  16. Hi @gpitts, thank you for your message. Sorry to hear it seems like you have run into some issues with your Ultimaker. A flooded head can be quite a hassle to recover from, depending from the size it might be better to replace parts than to recover. Sometimes if a part is slightly bent, you should be able to bent it back. By default this is not a good or bad practise, but it really depends on your situation. If consecutively you started having communication errors this might be a sign that the flooded head caused some more harm than 'we' initially thought. I trust you will be able to wor
  17. Hallo Eigentlich braucht Cura immer das doppelte von Nozzle-Ø (linienbreite) an Wandstärke um das "ordentlich" zu drucken z.B. bei 0.5 Wandstärkte wird Cura eine Linie mit 0.4 drucken und die "andere Linie" wird mit 0.1 gedruckt, also der Flow wird über 75% reduziert. Kann funktionieren, kann gut ausschauen aber auch nicht. Cura wird immer 2 Linien fahren, an jeder vorhandenen Wand eine. Selbst oben bei deinen geteilten Model fährt Cura zweimal (die wo gedruckt werden) Zu Print thin walls wenn es funktioniert wird nur eine Linie gedruckt. Abe
  18. It seems there went something wrong, please contact your reseller, it is brand new machine, so don't tinker yourself.
  19. You can always design your own supports in CAD, thus as part of the drawing itself. Then you have total freedom of design. When printing in PLA, you could for example design all supports in PLA too, except for a small interface layer of PVA, so you can wash away that and get nice clean undersides in your model. Automatic tools are great for general use, but for very specific cases, it is best to do it yourself I think. The automatics can't know what you have in mind. See a few examples here: This is how you could make custom supports in PLA, and have only a thin P
  20. Ok I will investigate this code ... def _onSelectedFaceChanged(self): if not self._select_face_mode: return self._handle.setEnabled(not Selection.getFaceSelectMode()) selected_face = Selection.getSelectedFace() if not Selection.getSelectedFace() or not (Selection.hasSelection() and Selection.getFaceSelectMode()): return original_node, face_id = selected_face meshdata = original_node.getMeshDataTransformed() if not meshdata or face_id < 0: return if face_id > (meshdata.get
  21. thanks Torgeir 🙂, it seems strange that small plastic particles could cause so much of a problem. I'll give it a go 🙂
  22. Alles klar, dann ist es nicht der DDG (wie im Titel gesagt). Der DDG-Extruder wird ohne Motor geliefert und ersetzt einfach 1:1 den UM2+ Feeder. Der UM2+ Motor bleibt dabei unverändert montiert und nur für diese Kombination gelten dann die 311 steps/mm Evtl. hast du das "QR"-Kit verbaut? Dann müssen die Steps geändert werden auf 492.45 - das ist auf der Bondtech-Seite auch so angegeben. Im Zweifel zeig einfach mal einen Link oder ein Foto von dem, was jetzt eigentlich montiert ist...
  23. Hi Adam_UL, You need to clean out the "old" plastic partickle's out of the bowden tube, -this as they increase the friction in the tube and increase the "drag forces" when pressure is needed to feed the filament. This pressure is kind of high when printing first layers and your feeder cannot feed properly due to this. It's very important to clean the feeder to prevent those partickle entering the bowden tube. A clean bowden tube will have much longer service life. You can use water(then dry) or air, some even use mechanical stuff as a "little" piece of rag, -but not
  24. With these results after the first 10 layers 😢. The Support material (mat2) is working fine, I've just removed it. Material 1 does not seem to be being extruded.
  25. Grid and Item does not show. Cura is working properly on admin account, but does not work properly on another local account. Kindly assist. Thank you
