  1. Past hour
  2. This looks like severe underextrusion, which could be caused by a lot of factors: too low temperature, partially clogged nozzle, worn-out teflon couplers, incorrectly mounted bowden tube, dirty feeder, slipping feeder due to wrong tension, too high speed, wrong filament diameter or setting, too much friction in the whole feeding traject, spool wound too tight (often when almost empty), material decomposing in the nozzle, way too moist, and so on. Somewhere on this forum there is a good list of causes (but I don't remember the name exactly), or google for underextrusion causes on the internet. I made tests some time ago, and yours looks like an extrusion-rate of maybe 50%? (Pictures are a bit out of focus due to taken on a dark winterday, but you get the idea).
  3. Today
  4. I believe the U3Ext has the latest firmware. It's currently printing so I can't look it up. Huh! I didn't realize the .6mm ruby print core was "CC". No. I do not have one of those. I currently have both original AA 0.4mm cores. I own two AA 0.8mm's & a BB 0.8mm which have been installed at one time, but not now. I'll try a Cura Connect reset tomorrow and report back.
  5. After I had my WiFi card replaced at the reseller, I was able to update to the latest firmware successfully. So far so good. Although I've only done a few basic prints. And I can turn the frame light off!!! At last 🙂
  6. Wie schaut bei dir der erste Layer aus? Ist der Plan? Die Wände sehen alle in Ordnung aus. Nur der Boden. Wenn bei mir die Haftung nicht vollständig ist heben sich einige Bereiche an. Wenn es zu viel ist und die Bodenstärke zu gering ist schaut es bei mir ähnlich aus.
  7. when you use ->preferences-> multiple build plates, a little window down left appears, where the numbers are visible and clickable. It seams to be a bit of a forgotten, unfinished, but handy feature.... you can click an item in the list and the model lights up, but if you click a model it is not highlighted in the list.. And you cannot drag the window, it is overlapping with the model text
  8. Ich habe es nicht geschafft, manche Einstellungen (Combing off, langsam drucken) helfen, es wird besser aber ich komme nicht an die Qualität von PLA heran. Andere produzieren aber sehr ansehliche PETG Prints, also irgendwie muss man es schaffen. Ich habe allerdings die Geduld verloren und drucke nur mehr in PETG wenn es unbedingt sein muss.
  9. As far as I know, no - I have never seen such a counter.
  10. You didn't 🙂 The S5 has thicker rods, better stepper motors, filament sensor, multi bed leveling, better feeders, can print abrasive materials, bigger build plate, touch display, front cover (doors) which is important if you print materials which tend to warp. But the UM3 is also a great printer, except the filament sensor, I would say reliability is the same.
  11. Yep je suis d’accord 30*C Max à tester. en tout cas cela m’apprend que les gros volumes creux ne sont pas très adaptés à la technique PVA , ou alors ne pas être préssé.
  12. Mm sounds like the list of printers is not coming back from the cluster. This can sometimes happen after a firmware upgrade. Is any of these things true: * Is any of the printers in your cluster (if you have multiple) on an older firmware version? * Do you have a CC 0.6 core installed on the printer? If not, try a Cura Connect reset on the printer's display, that will wipe any old data that might not be compatible.
  13. Hello, I think I have found a bug in the way Cura scales the models. When slicing one of these objects found here: https://www.thingiverse.com/thing:2753230 I wanted to do an EUR version and tried to "scale X and Y to 99.57% and Z to 101.3%" However whenever doing that it scales also other Axis or ...welll... hard to explain - generally scales incorrect values/axis. Try by yourself. Tested on Cura 4.0 x64 for Windows and Cura 4.1 x64 Beta - the result is the same. I worked it around by scaling with the size in mm instead of % even though it updates the percents in incorrect places (different axis) too.
  14. C'est pour cela que je préconiserai un système de soufflerie. Au moins pas, ou peu, de risque de déformation de la pièce. Et en plus, on peut y mettre tout les matériaux 😉 Mais pareil je pense que ce ne sera pas un système adapté pour des pièces avec des parties fines car elles risqueraient de casser surement. Après, si tu veux vraiment les passer au four, du coup il faut aller dans des températures un peu plus basses genre 30-40° car 50° on approche de la transition vitreuse où le matériau commence à ramollir.... Peut être que @DidierKlein a un tips pour les supports PVA?

    line width

    i have done a fair amount of testing with different line widths and repeated those since my S5 arrived, the thinner line widths used by default in Cura in general are not as good for overhangs, the thinner line width can lead to poor bonding on overhangs and some stringing. I have also seen lines not bonding together and leaving gaps with thicker line widths as mentioned above, however i have also seen this on the default thinner widths, so its not 100% that thinner prevents this issue, I think there is some sort of Cura quirk with gaps in perimeter lines and it seems to come and go. In terms of print quality i have found a slightly thicker than nozzle line width gives much nicer prints overall, esp on overhangs, I then increase the infil and wall overlap percentage to add some extra squish to remove any potential gaps. I also found that perimeter gaps were often present after a combing move if the combibg move was quite long and the nozzle pressure dropped, be sure to set the max comb travel with no retract to help prevent this Also gaps between perimeters can be very much material dependant, for example some PLA's do not have as good layer bonding properties as others and these tend to leave gaps more as the plastic shrinks as it cools and pulls the lines apart.
  16. https://ultimaker.com/en/resources/21932-mastering-cura Vielleicht hilft das weiter. Ein komplexes Thema. Aussendurchmesser in ABS sind akkurat, Innendurchmesser schrumpfen auch mal von 30 auf 29mm.
  17. Wird das Filament ohne Filter vom Drucker eingezogen dann kann ganz leicht die Nozzle teilweise verstopfen durch Staubpartikel o.ä.. Hast du solch einen Filter an deinem Filament während des Druckes: https://www.thingiverse.com/thing:190118
  18. War die Frage zu schlecht oder zu gut? 😉 Niemand eine Idee dazu? Im Cura Manual (Settings/Material, Settings/Experimental) finde ich leider nichts zu dieser Einstellung.
  19. I did try searching. 😎 I can see some differences listed but beyond nozzle options is there any real differences in the tech? Does the S5 have something that will give better/more reliable prints? Just trying to weigh up the value of the increased print size vs the cost over the UM3. Thanks
  20. I make a plugin, and I put it into the plugin folder of Cura 4.0 or 4.1, it works well. When I upload plugin in Contributor Portal, these is a Error message: One of the required files could not be found. It seems some files missed. How can I know which files missed? Attachment file is my cura plugin FlyingBearPlugin.zip
  21. Hey all. I am using 4.1.0 Beta. I'm no expert, but, is there a way to see how many models I've multiplied and / or imported on the buildplate in Cura? I have many, many small parts and if distracted, I may lose my count. Thanks.
  22. I was able to set up protobuf, though only through vcpkg, and now cmake is asking for sip cmake files for arcus, because I'm using vcpkg's toolchain, even though I have it installed in python.... here's the error. I can't find sip cmake files wherever I go, so I can only assume they don't exist? I installed sip and qt5 with "pip3 install", but are python3-dev (3.4+) python3-sip-dev (4.16+) as listed in the arcus build guide the same, or something I don't know how to get? I'm on windows, and this bit in the arcus guide looks like it's for ubuntu or something, but there is no windows guide! $ mkdir build && cd build $ cmake .. $ make # make install EDIT 2 alright. after some careful searching and looking, pip3 install sip does not install the needed files, and I can't find python3-dev or python3-sip-dev anywhere.
  23. The wall separation is almost surely underextrusion. Maybe 20% underextrusion. Try printing at half speed and the problem will probably go away. The reason it's only in some places implies you might have some "play" also known as "backlash". Try printing at half speed. Also I don't know anything about your brand of printer but if it has belts then they should be tight to reduce play. Typically 100Hz on a guitar tuner is a decent tightness for belts. Also push gently on the nozzle in X and then Y direction but not hard enough to move the steppers. How much can you move it back and forth? That's your backlash. Hopefully it's no more than 0.1mm.
  24. Yesterday
  25. Thanks Smithy - I will give the not in skin setting a try. Still researching the wall separation issue and going through the Cura setting resources for a possible solution, as it happens intermittently - usually around curves and sharper turns. Another example below of the issue where it's happening around the teeth, but not on the thin inner walls.
  26. Could be the filament swelling in the print core causing a temporary clog. Check the filament for grinding and the feeder for ground up filament. Check your print more regularly to catch the issue while its happening. Dry your filament. Or it could be poor layer adhesion caused by drafts. You need an enclosure when printing big parts especially with ABS.
