  1. Hi folks The build plate of my brand new Ultimaker S5 undergoes active leveling before each print. It results in either of my 2 extruders over or under extruding. Is there a way i can disable this active levelling process before each print, as i personally prefer manual leveling. The prints doesnt look that cool compared to the price i paid for this printer. Hope there is a solution to this.
  2. Does anyone have any ideas as to the causes of the visible layering in the picture? I'm using eSun PLA+ filament with the settings shown below and Ultimaker PVA (with built-in standard settings).

    XY-Kalibrierung

    Wir haben einen neuen Ultimaker S5, welcher mit PLA und PVA ausgerüstet ist. Bei der XY-Kalibrierung wird das X-Kalibrierungsmuster und das Y-Muster mit PLA gedruckt. Nachdem der Drucker auf PVA umgeschaltet hat fährt der Druckkopf alles ab wo gedruckt werden sollte aber es wird nichts gedruckt. Das PVA Material wird dann die ganze Zeit vom Feeder zurück gezogen und dann wieder nach vorne gestossen. Wenn ich allerdings ein Teil mit einer Stützstruktur drucke, dann funktionierts mit PVA. Hat jemand eine Idee was das Problem sein könnte?
  4. Hallo Ich habe schon ein paar Versuche gemacht mit einer Stützstruktur, leider druckt der Ultimaker S5 nicht sauber sondern schmiert das Natural PVA eher hin und es sieht auch aus als ob es zuviel Material ist. Es wird dann auch ins Teil eingearbeitet wo es gar nicht sein sollte. Ich verwende original Filamente, Standard Einstellungen des Druckers und Cura 4.6.0 Was mache ich falsch?
  5. Hi! I'm experiencing tons of problems using the material station with PVA material. Basically the problems I have are 2: PVA Brokes always somewhere in the path form MS to Extruder Flow sensor Error during print The first case obviously is the worst case, since sometimes in order to restore the printer i have to disassemble all tubes and push with ABS [i.e.] filament through the material station and get rid of broken pieces. This appened a few times using third-party filaments, so i decided to switch to Ultimaker filament of course, but then had lot more problems and the filament brokes even more easily then the other. ( had problems and broke the filament also when loading without material station, it was really too much dry) Left also the material a couple of days inside the MS to let him "adapt" to the ambient and then re-tried but problems where the same. As a last try, in order to verify extruder problems, I had disabled MS and printed a standard S5. No issues with both materials. in my opinion, the path of the fliament to the extruder is just too complex and dry PVA is too brittle to move along that path without breaking out. Do you have any feedbacks on this? anyone other then me experienced this? I bought MS in order to use it just for keeping PVA in a good state so it is really a pity that it doesn't work, but i really want to make it work so any help from the community or frm Ultimaker will be really appreciated. kind regards, Diego from Medics
  6. Greetings All, I've had the UM PVA snap in the bowden tubes as the filament enters the coupler (the rectangular thing on the back of the material station inline with the bowden tube) a few times. I've been able to recover, but would rather not have to go through that process too often. I've seen a few posts about this, but not much by the way of fixes. In both my failures they occured in the morning after the printer had been off overnight - material station is left on. I am wondering what the working temperature of the PVA is? I know storage is between 0c and 30c. I am guessing that the temperature in the room is somewhere between 0c and 5c in the morning if everything has been turned off. Don't have thermometer, just going by the outside temperature. How brittle does PVA become as it gets cold? Are there other things that can effect the PVAs mechancial properties that would make it more likely to snap? Also, the snaps occured at 50cm and 53cm from the end of the filament as it was being sent from the material station. Maybe that's helpful to know. Thanks, Robbo
  7. Hi Forum, My UM S5 can no longer print with Print Core 2. First I tried to clean the nozzle, but it turned out that a spring prevented the Print Core from being placed correctly inside the Print Head. Please see attached photos. I tried to place the Print Core, using a tweezers to push up the spring, while inserting the Print Core. But still the Print Core cannot print. I also tried with a new Print Core, but still no printing. I guess that the new Print Core isn't clogged, so that cannot be the issue. Does anyone know about this spring? Is something broken, or will I be able to push the spring back in the correct position? Does the spring failure have any relation to the non-working Print Core? Any help is highly appreciated.

  8. I have to buy an Ultimaker s5 and I would like to print the supports with PVA, on the site I found information that I cannot understand, the information is this: BB 0.4, BB 0.8, are they extruders to be purchased separately or are they other objects? Are they present in the package?
  9. Printer: Ultimaker S5 Issue: After running the cleaning option I was able to unclog the AA 0.4 core in slot 1. But the BB 0.4 core in slot 2, which has PVA loaded, will not unload, and therefore cannot be removed, and also is preventing any printing. When we try to disable core 2 in Cura and just print with core 1, PLA via AA 0.4, it still says that core 2 is overheating. We might not be able to get this serviced for several days to a week, so we're looking for a way to at least get the filament out and the core out. Our hope is to then just use our two AA cores to print with no PVA. If we pull the tube and cut the filament, can we pull out the core without heating it and initiating a core change int he software? Can it be pulled 100% manually? Additionally, we have only used the BB 0.4 core twice, and both times it failed. So we have not yet had a single PVA-supported print since buying the printer 1 month ago. The nozzle tip on the BB 0.4 also appears charred, after 2 uses, both of which failed within 10-20 minutes of starting. So this core has barely been used. Any tips would be greatly appreciated. Thanks!
  10. My company purchased an Ultimaker S5 for a job and we have been printing parts consistently for a few months now with the same print profile. All of a sudden, prints are beginning to be super inconsistent and most commonly coming out like the picture below. It is very important to resolve this issue as soon as possible as the deadline for the project closes in and we are falling behind on print time. I have tried doing (tons) of hot and cold pulls on the print cores. I have also switched the print cores out with replacements and run into the same issue. We currently have a new set of print cores on order and I am hoping this will resolve the issue, but in the meantime, what are your guys thoughts on what causes issues like this? Using Tough PLA with AA 0.4 and PVA with BB 0.4. Infill on 20%, printing at 215*C, print speed is 100mm/s, layer height of 0.25 mm.
  11. Hi, we try to print a support with overhang which needs support. Unfortunately, Cura does not put support on the whole area but leaves an area with no support in the middle. I assume, that Cura wants to save support material and thinks, that the printer will use bridging. This works in 20% of the prints, in 80% not. The first layer which is placed on the support fails quite often. I attached some photos and some cura screenshots. Is there a possibility to improve the slicer in a way, that it does not leave areas with no support? Or can one improve bridging? We are using Ultimaker PLA material for print and Ultimaker PVA for support. Does this bridging fail because of bad adhesion of PLA on PVA? As already mentioned, I attached photos, screenshots of slicing and of the support settings (basic settings from Cura) Thanks in advance for your help and ideas :)
  12. Hi Guys & Gals. I have encountered an interesting "Phenomena" where Cura (4.4.1) almost intentionally leaves certain overhangs unsupported when printing the support material with core 2 (PVA). Printing with an UM3, AA 0.4 and BB 0.4 cores, PLA and PVA. I have played around extensively with the parameters and settings and haven't found any solution yet. For the attached illustrations- I have set everything to default/standard: Model: Here is the model and the specific area of interest for me with the standard settings visible. Slice Preview: Here the preview SEEMS fine with more than enough PVA support all-round (Yes, I can set the XY ofsets ect to print less PVA blah blah but that's not the point of interest here) Problem: Here you can see that it leaves a big chunk of support out where it really SHOULD be putting support...? (Note here that I kind off despise the "Gradual infill steps" setting but understand how it can be beneficial but i mostly set it to 0). I mostly hope that it is me missing something extremely obvious, but it gets interesting; When I SWAP the extruders.... It supports it correctly. Swapping printing Extruders: Note that I only instructed cura to use extruder 2 for the model and extruder 1 for the support: I have tried multiple permutations of settings to try and get the PVA in the same manner as the PLA (eg making gradual infill steps 0, grid as support structure, density same as infill density ect ect ect but I am always left with this mysterious gap when trying to support that overhang with PVA.. Even tried putting the PVA BB core in Slot 1, and PLA AA to Slot 2 but the slice will still result in the unforgiving black-hole of "NO-SUPPORTNESNES" So for now I'm left with a dead light-bulb floating over my head until I can figure it out. Anybody maybe know what the obvious solution is that I am missing?? Okay love you guys, Cheers!
  13. Hi there, Last week, I started working with a UMS5, after some former experience with a UMO/UM2E. The first models, I did in TPLA, supported by PVA. After dissolving the support, I sometimes have a very unconsistent and warped layer. The bottom of my model that faced the build plate (rounded corner in the left is warped as well) looks quite terrible: Unfortunately, I don't have the gcode files saved. The settings in Cura are like this (translation below): Translation: Generate support / Support extruder / Support interface extruder / Support roof extruder / Support floor extruder / Placement support: everywhere Setup: UMS5 with glass build plate with glue, TPLA/PVA, air manager. I've been looking into this problem, but I cannot find a solution. Anyone any ideas? T_D
  14. Hallo Zusammen, Ich habe zwei Teile mal zu lange im Wasser gelassen um das Stützmaterial weg zu waschen. Dabei haben die Schichten angefangen sich voneinander zu lösen. Ist das Normal oder ist da ein Fehler beim Drucker/Cura?
  15. Hi ! I use an Ultimaker S5 and I have recently started having problems with preparing a part that requires PVA support. As you can see in the picture below, the support structure isn't convering the entire section of the part, it leaves a gap between the structure. I have been browsing around for other options in cura's support configuration but I can't seem to find anything that will fix this. I generally use Cura's default profiles for materials. Currently using Ultimaker CPE+ and Ultimaker PVA. - I am using Cura 4.4.0 BETA at the moment and I have a feeling this only started happening since. - So far, changing support placement from Everywhere to Touching build plate doesn't change anything. - I tried changing from PVA to Breakaway and the support covers the entire section, so this only happens with PVA. - Also tried with a diferente part and the same problem happens.

  17. Hallo zusammen, ich bin neu hier und habe eine Frage an euch. Ich habe bereits einige Modelle gedruckt, jedoch habe ich immer wieder das Problem, dass die Stützstruktur aus PVA sehr bescheiden aussieht und teilweise garnicht mehr gedruckt wird. Um diesem Problem entgegenzuwirken, habe ich mir die eSun Box zur Trocknung und Lagerung des Materials besorgt und die Einstellungen in Cura angepasst. Wie im Anhang zu sehen ist, hat der Druck ca. die ersten 10 Stunden ganz gut funktioniert, anschließend aber komplett versagt. Der Extruder bewegt das Material beim Düsenwechsel, also hat sich dieser nicht ins Material "gefräst". Was sind mögliche Ursachen für das schlechte Ergebnis? Kann der PrintCore defekt sein? Wenn ja, wie prüfe ich dies? Oder kann die Restfeuchtigkeit im Material trotz langer Trocknungszeit noch zu hoch sein? Für den Fall, dass meine Einstellungen schuld sind, lade ich die Datei auch nochmal hoch. Ich hoffe wir finden eine Lösung ! Beste Grüße Hendrik UM3_Flaschenhalter Ergometer.3mf
  18. Hallo Zusammen, Wenn ich im Cura die Teile Lade zeigt es mir zum Teil bei den ersten paar Layern an dass das Part mit Beiden Materialien gedruckt wird (siehe Bild). Habe ich eine Einstellung fallsch oder könnte das am Modell selber liegen?
  19. Hi, Everything works fine with Cura 3.6.0. Now, I just installed Cura 4.4.0 as I was interested in the Profiles, first and foremost the Engineering profile. I use Ultimaker filaments, black tough PLA and normal PVA, but it is not located at the back of my Ultimaker 3E, but in a Polybox. Unfortunately, Cura 4.4.0 says "profile not supported". I suspect Cura require that the printer recognize the filament at its back. What to do?
  20. Hello everyone, I am using ultimaker S3 with PLA and Natural PVA - as a support material(both ultimaker brand filaments), and I have been an issue where the BB 0.4 printer head is not extruding PVA, sometimes printing air in between the layers. Which will result in PVA not sticking on the print. The printer and materials are new and in good atmosphere condition. I have looked into the issue by: - cleaning the printing head BB 0.4 by means of cold pull/hot pull - reload the PVA through the feeder - adjust the tension on the feeder I have restarted the print and notice that material is not moving forward of falls back a bit every time and having ticking sound, then I have been having the error saying- "Nozzle offset probe failed. Please check the nozzles and bed and try again". (For cleaning the printing head, I have used the same PVA material. I guess, it wasn't the problem. Should I used the cleaning filament or PLA?) In cura, I have the correct options: Extruder 1- PLA and Extruder 2- PVA, have all default seetings for both material and also activated the 'prime blob' option. Attached, I have upload the Cura project and printed part-images. Please let me know, if anyone have any ideas. UMS3_finger-gripper-links4 -- test1.3mf
  21. hiya all. there are all sorts of solutions. I created a drum that went round the reel as a starter for ten. I have designed a case which I am yet to order the plexiglass for. however, I decided to try something different. A FOOD DEHYDRATOR. so I went for it, found one for £23,-. Initially I thought it would be a main section and had tiers inside it. however that wasn't the case. It is all made up from layers. So ok, I decided to keep 2 with their grated bottom and removed the rest of them. Idea is to contain 2 spools. I then designed a spool mount so they would sit nicely in the middle and allow to rotated. I then designed a tube holder to mount on the outside so that I can feed the filament without removing it from the Dehydrator. added a pneumatic fitting to hold the PTFE tube in place. and this is what I ended up with. there are two spools of PVA in there at the moment. and one feeding tube. (only because that's all I had) one of them has been playing up and low and behold, 1hr at 50deg and boom all was well. so for about £30,- I have a fully wooorking solution. I will upload the parts I designed. I am also going to make a frame to go around the feeeder so I can hold the feeding tube in place during retract. let me know what you think Rebekah Anderson
  22. Hi guys I have this strange 'problem' when printing with 2 cores. I printed this model with 0.2 mm layer height, but when the second core starts printing it looks like 0.4mm layer height. It looks like one layer is slightly more inwards than the other layer and the second core does exactly the same but on the other layer. I'm sorry for this weird explanation but I don't know how else to say it. 😉 This happens with (1)PLA and (2)PLA but also with (1)PLA and (2)PVA Has enyone seen this before and/or has a solution for this?
  23. Servus zusammen! Kennt jemand eine praktische Lösung das PVA nach dem Auflösen im Wasser wieder halbwegs zu binden? Wir verwenden relativ viel PVA für unsere Drucke und früher oder später kommt natürlich alles in den Abfluss, was mir nicht ganz gefällt. Wenn ich Zeit habe, lass ich es in einer Kiste austrocknen, dann kann ich einen dicken Lappen PVA am Schluss wegschmeißen. Gruß Andy
  24. Hello, I just got my new S5 printers, and am having some problems printing with both Ultimaker PLA and PVA. Basically, printing with only PLA works perfect, but when I try to use both, with PVA as support, the print head with PLA attached to it simply prints air, and nothing comes out. Note that I've tried cleaning it with cleaning filament, switching heads, pretty much anything of the basic solutions. When printing only with PLA everything works great, but when using both it just doesn't extrude. In cura I have the correct options: head 1 PLA, head 2 PVA (both pla and pva are Ultimaker), on the printer the same. Anything that comes to mind for my problem? Thanks a lot! Cosmin
  25. Hi there, I'm trying to print a part with an overhang and I really want to use PVA as my support material. I'm not sure if it's my printer or the material itself but it seems like my printer doesn't like printing PVA. I've attached some pictures of how my print when and honestly non of the PVA was sticking to my build plate. I believe that is due to a lack of PVA printed during the brim step. In Cura it shows the PVA on the brim but when it prints, there is not PVA part of the brim. I've only gotten the PVA to behave once before. I've noticed that whenever my printer tries to print PVA near the build plate, no filament comes out. The print head goes over the correct "tool path" but the PVA material doesn't extrude from the print head. If anyone knows what's going on, please let me know. Thank you!
