  1. Hi all, I am experiencing the issue pictured below. What I find odd is it prints the brim perfectly every time but when it then moves on to printing inside it the walls don't meet and the adhesion seems to get non-existent. Any suggestions?
  2. 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.
  3. Hello All, My first question in this forum But I'm sure I'll have more. I'm using Cura 15.04.6 to prepare my files to print with 1.75mm Hatchbox PLA on my ONI Kage Tall. I'm trying to keep detailed records about estimated print times as well as estimated weight of each print. And when each print is done I also record the actual print time so I can compare it with the estimated time. I know this is pretty standard operating procedure but I'll say it anyway. The reason for recording the est. time and real time is so I know when to go remove a print and start a new one if I need to. the reason for recording the estimate weight is I can figure out if there will be enough on any given reel of filament for the next print, or to see if maybe it's time to put on a different reel sp I don't run out of filament mid print and waste time and material. So what my question is, are the estimated time and estimated print weight directly related to each other in a reliable and constant manner. Here is what I've encountered. CURA 15.04.6 has consistently over estimated my print time and not by just a minute or two on my longer prints. Here is an example of a recent print: Estimated Time - 35 Hours 28 Minnutes --- Real Time - 30 Hours 37 Minutes. So in this instance my actual print time is 86.32% of the time estimated by CURA. Could this time ratio be applied to more accurately figure out how much filament was actually used? The estimated weight of this print was 517 Grams. Would it be reasonably accurate to calculate this to be 517 x .8632 = 446.3 Grams? I know the simple way to figure out how much has been used off a reel is to physically weight each print, but I don't have a gram scale and was hoping this maybe a reasonable alternative? Thank you, Kim
  4. Hi, Would anyone be able to tell me what settings need to be modified in Cura in order to sort out these features in the photo. Towards the top you can see gaps in the print as if no filament was extruded for the walls. Also how do i sort out the rough surface?
  5. Hello all! I hope you are all doing well! Recently, ive woken up to prints that have a surface that almost looks dented. After hours of searching on the internet, I came up empty handed. Does anyone know what is happening? Printer: Ender 3 Print speed: 25mm/s for,walls Infill: 10% Shell width: 0.8mm (220c for nozzle and 60c,for bed). Feel free to ask for any other settings! Thank you in advance!
  6. Hi! I'm aware that the title isn't very clear - but I'm not sure how to describe it - hence the "strange" 🙂 As you can see on the photo, my first layer shows these patterns. There is no problem with layer adhesion or whatsoever - the layer comes out flat and shiny, but with these patterns. Has anyone seen this before? Any idea how to fix this? Printed on an U2+ with U Silver metallic PLA. Standard settings for the material. thanks, Anton
  7. Hi Guys, Have been trying to figure out why our printer keeps on printing inconsistently. The material used is PLA through a 0.4mm nozzle. Adhesion to the new Buildtak looks good as the first layer goes down well on the footprint of each part and the skirt - bed has been calibrated many times and I think this is good due to how well the first layer goes down. From the first layer onward is when the issues start but I can't see to figure out what or why it is doing this: The models are raised 3mm from the bed to try and prevent warping also Appreciate the help - bit of a newbie to Ultimaker printing...
  8. 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).
  9. I changed a broken pneumatic coupler and ptfe tubing and after that I started experiencing horrible prints on my printer. What should I do please help me.. I use a anet et4. And cura slicer.. I tried to calibrate my esteps but the printer wouldn't respond.. So I printed a test cube.. What should I do! In order to get back to printing my minis. If u have a anet et4 pls share ur cura profile.. Ps. Am a noob so pls help me..!
  10. Hi, I've an Ultimaker 3 and have been using it since it came out. The NFC spool holder never worked but it doesn't bother me much so I never try to investigate. Last week I went through the menu on my Ultimaker (for fun) and noticed that in the NFC hardware Test in the Diagnostic menu says NFC hardware not detected I disassembled the spool holder and noticed that the cable is detached, I reattached the cable and check Diagnostic again, and now it says NFC Hardware detected I was super happy and then proceed to load my material, but it is still not detecting my Ultimaker filaments. I go to the NFC reader test and this is what it says ID: 0444783acb5281 UNKNOWN ID: 04f0ad5ad26480 UNKNOWN My spool 1 is Ultimaker Silver PLA My spool 2 is Ultimaker Red PLA The materials are put with the NFC facing each other at the center. It would be nice if someone can point me in the direction to get it working.
  11. Hello. We have recently bought the AA0.8 nozzle for our s5 to speed up productivity. We have been attempting to print visor straps but cant get the required quality. We have tried with the cura presets but to no avail. on inspection during the print i noticed that the nozzle was dribbling in some areas, never the wall but subsequent material would push these blobs to the surface creating a rough outer surface. we have tested with temp changes and speed, does anyone have any ideas? any advice would be gratefully accepted! Thank you
  12. Hi everyone, my printer started printing bad infill and then it prints in the air. How do I get this fixed? thanks for the help
  13. Bonsoir, Mon filament a beaucoup de mal a passer dans le tube bowden, auriez vous une solution ? Merci.
  14. Hello All, I am relatively new to 3D printing. I am having issues with the Cura Slicer while printing on my Ender 3 Pro. Whenever I have my 3D model ready in Cura then save the GCODE and start printing, the PLA will not adhere to the bed at all. Now before you stay bed leveling, temperature heating or bed adhesive. When I use the Creality Slicer without fail the PLA adheres to the bed. It seems to be the strangest thing and I don’t understand what could be the difference between the two slicer softwares especially since I have read so many good reviews about Cura Slicer. I have tried several different profiles in Cura with no success. I have even taken the Creality Slicer advanced setting and copied them all into Cura and still the PLA fails to adhere with Cura’s GCODE file. Any helpful tips or tricks would be greatly appreciated!
  15. Hi guys, I noticed that Cura is doing a strange thing that only happens when i have lots of things in my printer bed. Before I save the files I can visualize them correctly but after i save it to Gcode and reopen it shows strange interruptions on cylindrical walls. Above are some images to show what I’m talking about. I don't know if it's something i should be concerned about but this is a little weird and does not happen when i print (save) part by part. Hope you can give me some thoughts about this, I’m counting on your experience to guide me. Cheers,
  16. Hello to the Ultimaker community! Just to tell you guys that we are making the most out of our brand-new Ultimaker S5, by printing Protective Face Shields designed by Prusa Research, to help our hospitals fight the Coronavirus (COVID-19). Our Ultimaker distributor in Greece, Thes3D, have kindly lent us an Ultimaker 2+ to add to our production capability, and have even given us some spools of filament for our prints. Many thanks to them! The Ultimaker S5 has been a real workhorse, printing 24/7 for about a week now, and we have never had a failed print so far! Everything is running very smoothly and I'm extremely pleased with its quality and reliability, as well as its speed (printing on Draft Profile at 0.2 mm layer height, due to the urgency of the situation). Just want to express my thanks to Ultimaker for creating such a wonderful machine. We had some issues earlier on, but they were all sorted out to our complete satisfaction by our reseller in Greece and Ultimaker HQ, whose response was immediate and effective. I'm very pleased to be a user of this machine. I've taken the S5 home to ensure 24/7 printing, and the devil in me wants COVID-19 to keep spreading, so that I can keep it at home printing away... I'm only joking of course! One thing that came out of all of this, is the strong spirit of support, cooperation and contribution from the 3D printing community, always being on our side and offering a helping hand in these times of urgency. Thanks guys! Stay safe, and happy 3D printing!
  17. Hi I have a ultimaker3 and work normally fine. but i have no a problem that the PLA core is not feeding anymore. Initially i thought there was something with the reel as the feed wheel was grinding in the core. Changes the spool and again it happend. 2 Spools and 3 product that on the exact same spot start to get faulty. The feed unit has been opened to check, cleaned of small dust, knurling on feedwheel is fine, main gear wheel seems fine. infeed of new material goes smooth Anyone who has a clue?
  18. My UM2+ (UM2 w/ Extrusion Upgrade Kit) recently started having print quality problems especially on the first layer. After first thinking it was a leveling / distance issue and re-leveling the ben many times with no success, I started to look for other answers. Reading through posts here and other articles, I believe it is under extruding but looking for confirmation and ideas for fixes. After a failed print, it looks like the feeder is grinding the filament so assumed that the problem was on the hot end. I've tried everything recommended, cleaned head using the atomic method, removing the head and soaking in acetone, I'm getting clean pulls from the atomic method at this point (it wasn't bad to begin with). I've even opened up and cleaned the feeder. Went back into CURA and deleted the app configurations folder to ensure that there weren't modifications to the default profile. Adjusted nozzle temps to see if that impacted flow (195-210) Still having the problem... Currently printing using CURA's generic PLA profile, .4mm nozzle, with Amazon Basics 2.85mm Dark Gray PLA. I've had many successful prints with this combo (same spool) before this started happening I've attached a couple of pictures of the first layer issues. Thanks in advance for your insights and suggestions!
  19. I have an Ultimaker S5. One day, I started having problems with prints, specifically near the top (see picture below). I don't have any problems printing objects with a perfectly flat top layer, but when it's curved along the top, the print just gets stringy and melty-looking. Any ideas what could be causing this? I print with PLA (Ultimaker and generic). I've tried all different layer heights and no difference.
  20. I am printing a pint glass of usual dimensions, standing up-right, but as I watch my printer work, I am noticing that the round o.d. of my part is more like a 100-sided round-ish polygon. Is there a way I can eliminate this appearance from my prints? Is it software, model, printer, or operator error? I calibrated my XY last time I loaded an AA 0.4 print core for use with breakaway material. Could something I did incorrectly during calibration be the reason for this issue?
  21. Hi, I'm currently using Ultimaker Cura to slice 3D models for my Monoprice Select Mini V2 3D Printer. Upon further inspections into my 3D models, I found that Cura consistently slice my 3D models with imperfections (see images). This problem is consistent with other 3D STL models that I have loaded to Cura, therefore what could be wrong with my Cura settings? I am currently using the latest version of Cura Ver4.6.1. Thanks in advance !
  22. Good night, I am having this error in pieces, only in one part of the bed. I understand that it may be a leveling error. But I already leveled it several times. What else can you think of that could be? It is only the first layer. I have rotated the piece 45 degrees the piece and discovered that it is only in that point of the bed. Thx so much.
  23. Hallo Forum! Ich hoffe sehr auf die Hilfe der hier anwesenden Experten! Ich habe folgendes Problem mit meinem Ultimaker 2: Beim Drucken (PLA) hört man in unregelmäßigen Abständen (vielleicht ein, zwei Mal pro Minute) ein Ratschen/Klacken. Aus Erfahrung weiß ich und ich konnte erneut beobachten, dass in diesem Moment der Druck des Vorschubmotors auf das Filament zu stark wird und das Filament für wenige Millimeter zurückrutscht, am Schleifrad des Motors vorbei. Wenn die Düse verstopft ist, dann passiert sowas dauerhaft, das Filament wird an dieser Stelle schnell abgeschliffen und der Motor dreht quasi leer. Das ist bei mir aber NICHT das Problem. Wenn die Düse teilweise verstopft ist, müsste es beim Drucken ja eigentlich mehr oder weniger dauerhaft zu "Under Extrusion" kommen, richtig? Das ist bei mir aber nicht der Fall, außerdem habe ich in den letzten zwei Tagen mehrfach die Atomic-Methode angewandt und die Düse so (hoffentlich komplett?) gereinigt. Mein Druckergebnis ist zu ca. 70-90% in Ordnung, aber immer dann, wenn das Filament zurück rutscht, entsteht für ein paar Sekunden/Zentimeter Under Extrusion (logisch). Es scheint, als würde der Motor zu schnell laufen. Kann das überhaupt sein? Kann es im GCode, durch fehlerhaftes Slicing, zu widersprüchlichen Angaben kommen, so dass der Motor stärker dreht, als es Düse und Druckmodell eigentlich verlangen? Oder bin ich mit meiner Vermutung auf dem völlig falschen Dampfer und der Fehler steckt doch in einer tw. verdreckten Düse?? Hier ein Foto eines meiner Druckergebnisse:
  24. Hi guys, Just a quick post to report that I'm experiencing blobs on my prints, using the latest firmware on my Ultimaker S5 (version: 5.5.12-20200226-UltiBot), and the latest Cura (version: 4.6.1). The print head just freezes for a few seconds (maybe around 5 seconds), and then resumes movement, but it leaves a nasty blob behind it, as the nozzle keeps extruding molten PLA while the head is frozen. The print is otherwise perfect. See attached image. The blobs may happen a few times, depending on the size of the print, and this results in a perfect print with a few large "pimples" on its outer surface, which I have to shave off using a razor blade. I'm using non-Ultimaker, but high quality PLA, the same that has given me many prints without blobs or any other issues in the past. With the older f/w and/or Cura (can't remember the exact versions), and after printing hundreds of face shields for COVID-19, I never experienced a single blob. During the course of using the S5, I've promptly updated the f/w and Cura whenever I was notified of updates. I started noticing the blobs about a week ago, but I haven't been using the printer much lately, so it could go a bit further back. I'm not sure if the f/w or Cura or something else causes it, but it's definitely there. I'm on Wi-Fi, if that makes any difference. I had to stop a test print I was doing earlier, due to a blob appearing on the outer surface. The attached image is from that print. I'm now repeating the exact same print with the exact same material and settings, but using a USB stick as the source of the data, and have switched off Wi-Fi from the S5 Network options menu. This is to rule out any network issues. Will report back when the test print completes (14 hours to go). Is anyone else out there experiencing similar behaviour? Any info, comments, advice, are greatly appreciated, thanks.
  25. After ca 100 3D objects the filament extrusion slowed down. The transport at the other side of the tube is faster, as a result, the tube goes off, printing is discontinued. This is getting harder, elevated temperature did not help (Ultimaker 2+, transparent PLA)
