  1. Hi I'm using a Rigidbot printer (based on reprap). It has like a 10" build plate. But for some reason Cura keeps pausing when I'm on the 3rd layer, (sometimes the second). It stops in different locations and even if I swap parts (that are the same rough shape) it continues to stop. At first I thought it might have been the cable so i replaced that but still getting the same result. The tallest print I've made is over 8" in height so I know it's not a duration thing... I don't know. I'm not sure what to do...
  2. Bonjour, J'ai récemment reçu une ultimaker 2 pour faire du prototypage. Celle-ci a déjà pas mal vécu et, après nettoyage et graissage des axes, j'ai procédé aux réglages pour passer à l'impression. J'ai donc calibré le plateau (plusieurs fois), fait la méthode atomique pour nettoyer la buse, nettoyé le plateau et fais des essais. Les petites pièces (environ 5 cm de diamètre) s'impriment correctement mais, suite au passage à l'impression d'un plateau de 70 mm de diamètre, la première couche d'accroche se relève comme si la chaleur et l'adhésion "tendent" les rebords. J'ai essayé plusieurs réglages de vitesse (je fais la première couche à 80%), de températures d'extrusion (je fais à 200°c) et de lit (je le met à 60°c) mais malgré cela, le bord inérieur au fond à droit je relève toujours petit à petit dès le cinquième tour. En essayant de positionner la pièce ailleurs sur le lit; même résultat. Le filament PLA semble assez agé mais présente une bonne impression sur de petites pièces. Il s'agit quand même de 3mm de diamètre mais je n'ai pas de problème avec le feeder dès 200°c à l'extrusion. Est-ce que je fais quelque chose de faux ou faut-il changer de filament? J'ai entendu dire qu'un filament ancien aura absorbé de l'humidité et qu'il serait intéressant de le régénérer au four (40°c pdt 3h)... Merci à ceux qui prendront le temps de me conseiller 😉
  3. New to printing and just got a tronxy xy-3. Having a few problems getting it dialed in. It's printing roughly 10 mm above the bed...sometimes. I'm not sure what I need to change but sometimes it will print above the bed and sometimes it will come down to where it should be. I have printed a few things...when it gets down to the bed. And they come out decent for now. If i move the Z axis and then try and print, It asks if i want to print from the current location. I'm using cura to slice. We 3D print where I work so I have a general idea of how to set the settings and how it should be printing. The magnetic bed also might not be the best for adhesion, has anyone else had adhesion problems with magnetic mats?
  4. Hi everyone, I'm having issues with the drive gears stripping filament on a dual colour PLA print. It seems to happen at random - both nozzles will be printing fine for a couple of hours and then out of nowhere one or the other will start having massive underextrusion and the filament will look as slightly torn up over a 10-15cm span out of the drive gear housing, and then the fatal groove where the gear finally ate too much. I'm using a "glitter" filled PLA with the 0.4mm AA print cores at 200C and 70mm/s. Here's a list of things I've tried to save people time suggesting things I've already done: - Changing the tension on the drive mechanism. I've tried it real tight, real loose and everywhere in between and the only thing affected is how much the filament gets chewed. - Thoroughly cleaning out the drive mechanisms, including cleaning the gears down. - Cold pull cycling the nozzles. I don't think the issue is clogged nozzles as filament extrudes freely without cleaning the nozzle out each time I have a problem, but I tried this anyway. - Changing the standby temperature from 100C to 160C and a couple of stages in between. - Changing retraction distance, limit and speed to try to limit the number of times the filament was run over the drive gear in the same place. Feel free to suggest any settings you know to work well for 2 colour prints as I'm not sure I've covered all the options on the retraction side of things! If anyone has seen this before or has any new ideas that'd be extremely helpful, thanks in advance! Glen
  5. Hi there everybody, i hope someone can help me before i lose my sanity with this one. on my UM3 extended, every print has recently been printing the first layer perfectly, and then suddenly printing like it cant extrude properly (shown on the photo). im using PLA 2.85mm, printing at 50 mps at 210 degrees as suggested by other forum posts, along with a print bed at 60 degrees that ive leveled more times than i can count in an effort to fix the issue. any suggestions would be greatly appricated and to help get me printing again!
  6. Bonjour à tous, Donc voilà, je comprends pas pourquoi quand j'ouvre un fichier pris sur Thingiverse, l'objet devient énorme avec des dimensions qui passent de genre 20mm normalement à 2000mm? à chaque fois je dois redimensionner et c'est pas toujours facile de retrouver les dimensions exactes quand la dimenion qui m'intéresse se trouve à l'intérieur de la pièce (je débute vraiment) et ca le fait aussi quand j'ouvre un fichier avec Cura depuis fusion 360... Merci d'avance
  7. Nothing I do will make these blobs go away except for switching to slic3r, but I'm having a world of other issues with that program so I'm still trying to get Cura to play nice. I have tried Flow, retraction, coating, z seam alignment, wall count, combing, retracting before outer wall, speed, almost everything and its making me crazy. Any advice regarding what other settings i can try or anything really would be appreciated. I have included the gcode, cura profile, and what my results were with coasting enabled, nothing enabled, and detracting before outer wall.

  8. Hello. I increased by 205% on the z axis. And at the time of printing, the impression is always defective as I show in the image. How can I solve this problem??
  9. Bisher drucke ich immer Schichten von 0,1 bis 0,2 mm Höhe. Ich kann mich daran erinnern dass ich mit slic3r PE (Prusa Edition) schon einmal erfolgreich 0,05 mm Layerhöhe gedruckt habe. Aktuell nutze ich Cura. Jeder Druckversuch einer Schichthöhe kleiner als 0,1mm endet bei mir mit ein em Fehlschlag, weil die Düse verstopft ist. Sie läßt sich immer Recht einfach wieder frei bekommen (durch einen "hot pull").Mir ist nicht ganz klar woran das liegt. Das Filament sieht nach so einer A kti on imm e r recht ähnlich aus: Man erkennt jeweils, das eine Art Stopfen am unteren Filamentende entsteht. Um ein wenig zu Experimentieren habe ich ein Testszenario erstellt, indem ca. 10 Quadermantel 150x5x6 mm^3 mit ca.0,4mm Wandstärke gedruckt werden sollen. Ich statte sie dann mit identischen Eigenschaften aus und variiere jeweils nur eine Eigenschaft. Z.B.: Druckgeschwindigkeit, Wandstärke, ...? Ich habe schon viel herum probiert, jedoch kommt eigentlich immer das gleiche dabei heraus: Nach hinten nimmt jeweils die Druckgeschwindigkeit ab (von 80mm/s bis 20mm/s) Hier Mal mit etwas Höher Temperatur (215°C): Und hier Mal mit etwas niedrigerer Temperatur (205°C) und ohne Kühlung. Im letzteren Bild sieht man, dass die Layerhaftung deutlich besser ist. das Tape Dreieck war ein Versuch gegen warping was da auftrat. Leider kommt es trotzdem zur verstopften Düse... Möglicherweise hat der verringerte Volumenstrom hier eine Auswirkung, da bei geringerer Layerhöhe ja auch weniger Material extrudiert wird. Eventuell wird das Filament "klumpig", wenn es zu lange erhitzt im Extruder war. Vielleicht wird es auch beim "zu langsamen" Durchlauf durch die Düse von der Kühlung zu stark abgekühlt. Filament ist übrigens vom Hersteller meines Druckers(Prusa i3 MK3): Prusa PLA ... Möglicherweise ist meine Methode auch nicht optimal (, was ich stark bezweifle, da Support und Infill auch nur aus einzelnen Perimeter bestehen!) ... Wie sind so eure Einstellungen, speziell die Beziehung zwischen Volumenstrom(Layerhöhe, Breite und Druckgeschwindigkeit), Drucktemperatur, Kühlung, etc.? Gruß nerd

    Problema con S5

    Ho un problema con la mia S5. Mi è capitato di eseguire stampe di 10 giorni filati senza avere alcun problema. Ho sostituito recentemente l'estrusore BB. Ho stampato ulteriormente dopo averlo sostituito senza alcun problema. Ora, mi ritrovo con un problema di adesione del PVA sul PLA, inoltre il PVA mi "incide" il modello sotto in PLA lasciando il segno. Qualcuno che ha una soluzione o un consiglio al mio problema? Ho provato di tutto, calibrazioni, parametri di stampa, temperature, velocità di stampa, qualità di stampa varie. HO fatto un sacco di prove modificando più variabili ma nulla. Il problema persiste. Ah, dovrei stampare il modello in qualità extra fine 0.06mm Vi ringrazio anticipatamente
  11. Hello everyone, I am having trouble with some strange underextrusion. In some prints, maybe 1 out of 10 and in only certain parts, the PLA is extruded in little pulses that increase in frequency untill they turn into a smooth line. This always happens at the beginning of a new layer, after z-hop and retraction. Due to this the print is massively weakened at these parts and shows striations on the surface. I managed to capture this on video and also have a picture of it, but I have no idea what could be causing this, especially because it only shows up every now and then. I would be very grateful for tips and help regarding the issue. Here is the link to the video: https://photos.app.goo.gl/G3TLKveMsLNRQmgv7 Thank you very much!
  12. Hi! Any clues why the BACK of the print looks near awesome but the FRONT looks like CRAP?? (sides look ok too). PLA print on UM2E+ with latest official firmware and olson Ruby nozzle 0.4 printing at 50mm/s. (Yes, I've checked the STL for manifold errros and the Gcode and both look fine) The printer has an enclosure installed but I printed this with the door open and the ambient temperature is currently low, like 16-18ºC and since the rear part was printed fine, I don't think it's about too much heat, plus the PLA i'm using has a higher melting point than regular PLA...
  13. Hi! I recently tried to print an stl with thin particulars and the print leaves some little holes, as shown on figure. I checked the stl but it seems to be perfect, without strange holes! How can I fix them? Actually I use cura 3.6.0 Thank you
  14. Hello everybody I`m in 3d printing for only about month and had a few problems earlier, that i managed to fix by my self, but this time I gave up. In many models, already had this problem, but small remake usually fixes it. But this time I can`t make it to leave it empty, Cura just fills up all the model. I`ll be thankful for any suggestions that could help me fix this.
  15. Hi Maker! My name is Markus and I’m a student of the university of applied sciences in Kufstein – Austria. I am seeking your assistance with my Master's thesis, where I examine the influence of ambient temperature and humidity on the success of 3D printing. Since I need a large number of experiments that are carried out under different climatic conditions, I would like to ask you to help me with this. I developed a test object with elements of the standard DIN EN ISO ASTM 52902 and additional features. I would send you the STL file of the test object, description of the settings for the experiment and a test report for evaluating, if you contact me. Additionally, I would be happy to hear about your experiences with the influence of different room temperatures and humidity values on the result of 3D printing in case you have findings that you would like to share (i.e. limits, critical environment, reliability). Thank you very much for supporting me with my master’s thesis, I highly appreciate it! If you like to receive the results of the thesis, I will gladly send it to you once it is finished. For this feel free to send me a message to markus.ehrlenbach@fh-kufstein.ac.at Best regards, Markus Test Procedures 2019v42.pdf Test report_2019v42.pdf Test_Object_v4_2.STL
  16. Looks like that but it should look like that: I am new to 3d printing (Student), I am currently working on a quadcopter for school and I wanted to print the frame, we have the Ultimaker 2+ in school and I gave my teacher the SD-Card and he printed it. Need a hint, how I can solve the problem. Is it the model or the calibration of the Z-Axis?
  17. hi @ All UM3 was doing a print job when there was no material left through the core1 print. I noticed and stopped this. Unfortunately, all around the printcore under the cover was Materal, see pictures. Does anyone have similar experiences? What could be the cause?
  18. Bonsoir à tous, Après avoir lancé une impression ce soir et attendu moins de 2h pour retourner verifier où en était le travail, nous nous sommes retrouvé avec la très mauvaise surprise de voir notre impression raté et même pire notre bloc complétement fichu par la matière qui a complétement imprégné le bloc Olson (fils capteurs et thermistance + buse comprise). Pourtant aucun problème n'était à signaler à part un décalage en hauteur (à peine 1mm) constaté par rapport au niveau réalisé juste avant de lancer l'impression. Cette mésaventure est-elle déjà arrivé à l'un de vous? Avez-vous des solutions à proposer? Nous avons pensé à démonté le bloc entier et faire chauffer le bloc dans un four pour enlever la matière. Merci de votre aide.
  19. Hi guys, My PLA filament is badly stuck inside the AA 0.8 Printcore and I am unable to pull it out (neither filament nor Printcore). Any suggestions/help on this will be greatly appreciated, photo attached (the extruder on the left). Thanks! Any suggestions on how I could remove the print core will help as well 🙂
  20. Hi all, I'm printing PLA+PVA and I'm using the prime tower. PLA is Extruder 1 PVA is Extruder 2. External material in prime tower is PLA (E1) and internal material is PVA (E2). QUESTION: Is there any way of choosing the internal and external material? In my case, the reason is PLA adhesion is much better, so it would force a better adhesion PVA ring around PLA. Thank you.

    Offene Wand

    Hallo, bin neu hier um Forum und habe gleich mal ´ne Frage. das meiste drucken wir in PLA ... und immer wieder haben wir das Problem, dass sich die Wand nicht richtig mit dem Innenleben verbindet 😞 Bestimmt gibt es da eine Einstellung in Cura oder so, dass das nicht passiert ... aber irgendwie finde ich diese nicht ... Wie das dann aussieht, habe ich mal als Bild dran gehängt ... ich bin natürlich für jeden Tipp dankbar 😉 Gruß Mathias
  22. Hey, For my first print I was wondering what the optimal position for my object(small box) would be? Right now it is oriented on it's bottom but there are some problems with the handle of the box and the two stoppers on the side which would need support. Cura also indicates that the letters and number need support but these protrude only 2mm(at max). Do these elements need support? I can also position it on the back of the box instead of the bottom but then it will need alot of support (I suppose) in order for the front panel to print good. What would you advise? Printing on an aquintance's MakerBot Replicator 2 (which as far as i know only takes PLA(?)) box dimensions: 51(width) x 34(height) x 64.2(depth) Some images of the box & .stl attached Thanks, a. 3DP_Brause-1.5-test.stl
  23. Hi guys. So I was trying to print something for my project this morning. I load a new gcode file on the thumb drive and load it into Ultimaker 3. Once it finished leveling and started to print, I noticed that it became dotted lines. I don't know how to describe it but I've attached pictures for you guys to take a look at. Did you guys ever encounter something like this before? If you have any idea on how to fix this, help a bro in need.
  24. Moin, ich habe mal wieder ein Problem mit meinem UM3E. An sich habe ich an der Druckqualiät nichts auszusetzen.. bis auf die scharfen Ecken, an denen ist Ringing aufgetreten, oder Ghosting, wie auch immer. Zu dem Problem hab ich hier ja schon einmal einen Beitrag gepostet. Jetzt glaube ich allerdings dass das eine andere Ursache hat. Ich bin nämlich der Meinung, dass die Schatten durch die inneren Wände entstehen, also dort wo eine Wand endet, entsteht ein schatten. (Ich hoffe das ist so einigermaßen verständlich?) ich habe nun ein Mal versucht nicht von außen nach innen zu drucken, das hat auch etwas verbessert, aber richtig gut ist das immernoch nicht. Hat jemand eine Idee, mit was für einer Einstellung man das in den Griff bekommen könnte? Liebe Grüße
  25. Hi all, Cura 3.6 Brim layer is made with PLA but brim support layer are with PVA directly on the platform. Why I obtain these few PVA lines on the PLA brim? in this way I have many adhesion problems in these 10 lines. I wish all PVA on platform. How can I select PVA support ONLY in build plate? (yellow: PLA; purple: PVA) Thank you.
