Hello, which printer are you using and what type of filament? It looks like your bed is too far from your nozzle when you start printing and perhaps there are is room for some cooling optimisation based on the stringing in between the pedestals at the top.

Hi Nighthowler, thank you for your message and welcome to the community! Happy to hear you found an Ultimaker. The top minical test doesn't look too bad. You can see some stringing in between the pillars which could be something for you to look into to improve. This minical gives you an opportunity to see if your belts are tight enough (sharp corners), if your cooling is working (stringing, molten layers), and if your extrusion is on par. And it could show some other artefacts if something was not correct in your motion system. I am curious about the material. Did it come with your Ultimaker 2? If it did, it could be a rather old reel of PLA (a long time in the past we used to ship the Ultimaker 2 with a reel of Ultimaker blue PLA). If so, the age of the filament could have something to do with the stringing, and I would recommend to try a newer roll before you dive into the settings which might be dialed in correctly. Good luck!

Because the assembly is rather complicated and delicate, and requires special tools. Taking it apart is no guarantee that you would be able to put it back together correctly again. There might be some video's online that take it apart, but those are not instructions that we officially support.

That is correct, there are no spare parts available to repair a print core.

Hi @up3d, thank you for your message. I'm sorry, I'm not entirely sure what you mean. Are there any questions you can not answer? If the question does not apply to you, like a state in the US or a company name then you can also fill out N/A. We do need the input from the form, including the checkboxes at the end in order to put you on the map.

I discussed this thread with a product expert before the weekend too, and he also suspected the infill but I didn't get a tangible reason. Developers monitor both, but to be sure we can tag @maht in here. @maht, do you know if this bug is already registered?

Thank you for sharing your updates with us @CTotten! Looks like the gyroid infill might have something to do with the inaccurate estimated print time, does it not?

Great work @DrCeeVee, keep up the good work and stay safe. Let us know how it is going and if you need any further help down the line!

Hi @DrCeeVee, I'm very happy to hear you are both happy with your Ultimaker, but even more so that you're putting it to good use printing face shields. Have you also filled out the form yet so we could potentially connect you to a local hospital if they would be looking 3D printed aid? Alternatively, we've seen a couple of hubs and initiatives switching to this design after it was approved by U.S. Department of Health and Human Services; https://3dprint.nih.gov/discover/3dpx-013306 Maybe it helps. Whichever design works best for you and the institutions you are trying to help!

Hi wrong. 😑😂

Hi Thank you everybody for getting back with me. Are your printers still available for new commands, except it's 'just' the camera that is not working? Or is the entire connection lost? I checked with our product experts, and they've informed me that in the upcoming firmware release there should be a fix where the camera should be able to regain connection after it has lost connection at some point, which should result in a much more stable experience. The exact release date is not known yet, but you might find it comforting to know that a solution is coming!

Hi @abrgome I've created a new topic for you in the correct sub-category (Cura). This increases the chances of someone reading your question who knows the answer. Perhaps, in the meantime, you can elaborate a little bit on your question. Is Cura not producing gcodes, or do you not know how to do it? Thank you,

Happy to hear these positive responses! When the last part of the filament is attached to the spool, the decoupler should detect this, unload the filament and select the next similar spool if you've loaded one. So even when you have deactivated your flow sensor this should still work. So I would suggest you give this feature a try to prove itself 🙂 Good luck, and let us know how it went if you decide to do so.

Hello, thank you for your feedback. Did you eventually figure out step 2 and 3? Regarding PVA, this is a very sensitive material to print with and certainly has its challenges. This is because it dissolves in water, which makes it absorb moist from the air too. Loading it in the Material station is a good method to keep it dry, but it is important to realise that it doesn't make it dry. It is not a dryer. It is recommended to dry PVA before you start using it, to remove any moist that got in there even before it was sealed. If you can then load it in your Material station, you should be pretty safe. If you don't have a material station, try to store it in a dry location, preferably sealed with silica packs. The default tension on your feeder is right in the middle. You could try to set it a little bit higher (so the indicator goes higher too), but not by much. Talking millimetres here. If you found other PVA that works better, I'm glad you found a method and material that works for you. That is one of the benefits of having an open material system! Have a great day and stay safe!

Dear Tiago, Thank you for your message. Our apologies if any of our resellers did not live up to your expectations. It sounds like you have a rather unpleasant experience. Please allow us to look into this and we'll get back in touch with you shortly.

Hello, I hope you are all well. Tomorrow we'll migrate our technical support system to Zendesk which would allow us to work more closely with our sales partners, towards faster solutions for you, our customers. We know that it is not uncommon that people visit the forum because they have an issue they need help with. For that reason, we'll incorporate 'Official support' in our top menu so when you are in need of support you can visit our knowledge base or our technical support engineers in just 1 click. You will see that Calendar, Leaderboard and Our Picks will disappear from the menu to make room for 'Official support'. This does not mean you can't ask our community, product experts or Team Ultimaker for help anymore. We'll all still be here. We'll even monitor the community to learn what frequently asked questions are, and try to incorporate them into our knowledge base so it stays relevant. Usually, anyone wants to have an answer and move on with their business as soon as possible. Finding your answer in the knowledge base without needing to wait for a reply, is probably the fastest way forward. And if you can't find it, you are always free to ask us 🙂 Stay safe everybody!

Hello, thank you for your reports. Let me check with our product experts if they can shine some light on this. It is indeed possible to print without an Air manager, but by having one installed you do physically block a lot of warm air from escaping, which can be good when in a controlled fashion. If for some reason the Ultimaker S5 lost its connection with the Air Manager, and it is not restored, it doesn't know that it is still on there (or running), and shuts down out of precaution. If it would continue to run, the heat could get trapped insight and deform/soften your slider blocks for example. I'll get back with you tomorrow, thank you for your time and apologies for the inconvenience.

Hi guys, thank you for reporting. It is a known issue where the printer sometimes can run out of memory and due to prioritisation it drops the camera feed to ensure the other crucial print features remain operational. A poor wifi network could also be a reason, albeit a different one. We've significantly reduced the chances of this happening now if you run 1 Ultimaker. If you run multiple in a group, the chances of this occurring are still a little bit higher. Can you let me know if you run 1 or multiple Ultimaker S5's? If it is multiple, can you share your log files with me? Thank you for your time and our apologies for the inconvenience.

nice job, you can barely tell which one it is!

Dag Willem, wellicht kan het zijn dat de kabel los zit die het display aanstuurt. Heb je daar al naar gekeken, of weet je hoe je dit moet doen?

Hi Roger, welcome to the community and thank you for your message. Which 3D printer did you get to start with? And for what particular reason have you not printed any other models? Does the 3D printer not work, do you not know how to design in CAD, or do you not know where to find other models? Thanks!

Hello! Some of you asked for an update of what has happened up until this point. A lot! We've been very busy and many wheels are spinning at the same time. I found time and tried to cover some of it in our (first?) update post. If you have a moment and if you are interested, you can find it here. Thank you for your time and interest in this cause.

The COVID-19 virus has a firm grip on our world, and its effects are undeniably impactful. Significant pain points are starting to surface in the medical world, where the amount of people who need help increases, but the supply and distribution of tools and equipment has a hard time keeping up. At Ultimaker we recognised this as an opportunity to help, activate our network and utilise the disrupting power that local manufacturing can have. Through this post we would like to share some of the things we have already done so far and some tips that might help you to help others. What have we done so far From our experience up until this point it seems there is a high demand and a lot of good intentions, but in between these two forces we still need to identify how 3D printing can be put to best use. Unfortunately, not everything that hospitals need can be equally easily 3D printed. Luckily, sometimes even an easier solution is just around the corner. The experts on team Ultimaker together with medical professionals are helping to identify where 3D printing can help, or what accessible alternatives are available from a vibrant network of (professional) makers. Here are some examples we’ve come across so far: Face shields. (Single use, very large quantities) The city of New York was tasking the industry to first deliver more face shields for intake and test staff at hospitals — in the thousands. We helped them by printing a face plate in the New Lab 3D Print Lab, while also being supportive of the team cutting the face plates with cnc routers. With Bednark, the company with the many routers and faceplate material, we all identified a reasonable and viable route just using foam and faceplate material — a route that would reach the 10k desired pieces by the end if the week. Additive manufacturing was validated as a secondary option but considered not fast enough for such a large batch and not as comfortable to the face as a foam strip. Additive manufacturing solutions are considered for other projects. Protective masks (reuse required, medium quantities) The priority for hospitals is protective masks for closer physical proximity to COVID-19 patients. There are a lot of designs but no unanimous agreement. A large group of industrial designers are using 3D printing trying to get closer to a conclusion in discussion with many hospital staff members. This is a candidate of additive manufacturing, but the exact solutions we’re still working towards. Right now none of the existing designs have been deemed safe enough, a good enough fit, nor nimble enough for what doctors need moving fast. It’s a work in progress for which we are committed to reach a conclusion. The New Lab 3D Print Lab is ready to run validation prints and quantities in hundreds this week when a good design is found and validated by NYC hospitals. And when we reach that benchmark, other local hubs and localized manufactures (like Voodoo manufacturing) could makes thousands as a stop gap until other processes deliver. Ventilators (reuse required, mechanical solution, lower quantities acceptable). The main project right now seems to be the MIT project. Most of the medical contact parts are being water-jetted and CNC’d from medical grade plastics. The 3D Print lab stands ready and available for all prototyping, but the key issue to solve are electronics quantity and firmware and some sewn parts. Other medical parts for hospitals: (emergency parts with size/fit interface requirements but low sterilization or quantity requirements possible) As functioning mask files are not confirmed yet, the New Lab 3D Print Lab has reverted to close to original aim for initiative: as a read printing hub for hospital emergency parts directly instead of supporting government of city of New York. These are all AM opportunities. We’ve also been in touch with numerous medical professionals and institutions, testing and validating various designs in different applications. This will be an ongoing work in progress with new designs entering the field. Due to risks and liabilities we can’t share these results yet, but we hope to share them at a later stage. Including a list of materials which are best suited for certain applications and the specific requirements they might have. How to help others If you are on our map of available 3D printing hubs (if you’re not yet, you can by filling out this form), it is possible a hospital or other medical facility can reach out to you asking support in either designing or printing a certain tool or application. The following questions or considerations can help you zoom in where additive manufacturing can really help and where, truth be told, we probably shouldn’t. Despite the urgent need and enthusiasm to help; not every request is equally suitable or 3D printing. If you receive a request, ask yourself at least these things: Is the request approved by, or did it come from a medical professional? Our willingness to help could overshadow potential health-risks we ‘common folks’ are not aware of and we should be sure that any help we provide is actually helpful. When in doubt, feel free to reach out to us and experts in our network can advise. Is 3D printing the best manufacturing method for this application? This may often be the case, but not always. In our attempt to help we must find the balance between what production method is best suited, and what capacity is available on short term. Does the application require specific material properties? Make sure to validate with the medical professional who requests your help which material you should use, or which properties it must have before you start 3D printing. If you attempt to print with materials that are new to you, familiarize yourself with potential emissions and adhesives before you start, and take the necessary precautions. Can you print under sufficiently sanitary conditions? Think of allergens that may spread from pets when printing from home, and think of your own health. If you are feeling ill, stay isolated and get well first. When all the above checks out; do you have sufficient 3D print capacity? Feel free to involve other hubs in your local area to assist. Depending on which surfaces or fluids a 3D print is in contact with, it may not be useful for repetition or longer periods of time due to the coarse surface of an FDM print. Keep this in mind when you discuss certain applications or your choice of materials. Our experts, together with medical experts and institutions are working on making a list of materials and instructions which can be sterilized, and which can be used at certain grades of medical appliances. We will share this as soon as it is validated and complete. If you have any questions, feel free to write them below or reach out to us directly. Thank you for your time and stepping up to help others in this time of need. Together we can make a difference. And stay safe!

Hello, thank you for your message. It is not necessarily the weight that I suggest to capture in a camera, but it is indeed under extrusion and sometimes the way that it manifests can be a lead to the reason. Could you also share a picture of your print head, and the way the heater cartridge and thermocouple sit in your aluminum block? If not inserted fully / correctly, this can also lead to heat loss or incorrect measurements. The slit 1/3rd in your print could be because of dirt on your threaded axis on the back. Have you ever cleaned it? If you clean it, make sure to reapply the grease you have received together with your Ultimaker Original.

Hi @cubic, thank you for your message. In addition to your thorough description, could you also post some pictures of your prints? That will probably also be a valuable tool to assess what might be wrong. Thanks!
