  1. Hi RogerBW, this seems a very common issue which is simple to fix. There's a good tutorial by @fbrc8-erin: The video refers to an UM3, but as the sliding blocks are the same for the UM2, you can refer to it 1:1. Regards
  2. Hi, if the short belt is not moving, it may have two possible causes: the stepper motor is not working (defective motor or defective cable/plug) if the stepper motor works: the pulley on the motor shaft is lose (retighten the pulley) If the belt is moving, but doesn't operate the print head: check the pulleys on the upper axles for slip and retighten the set screws if needed, possibly print head alignment is required. Regards
  3. Hallo, funktioniert evtl. das Umschalten der Druckköpfe nicht richtig? Dann müßte der Umschalthebel neu kalibriert werden. https://support.ultimaker.com/hc/en-us/articles/360011474120-Lift-switch-calibration Grüße
  4. The most common ways are posting a youtube-link (will be automatically embedded) or a cloud link.
  5. Hi, possibly the lift switch is grinding at the sliding block (check for traces). To avoid this you could do the lift switch calibration procedure, but instead of fully seating the lift switch in the switching bay while calibrating, you could back it out just 1mm to prevent touching the sliding block. Regards
  6. Ok, the pictures really clarify your issue, which consists of stringing and some "insect antennas" (two terms worth searching the forum 😉). I assume the material you're printing is CPE or PETG? There's good and bad news: good as these artifacts can be reduced or even avoided by fine-tuning the print settings, bad as this is far beyond my knowledge and I can't really help furthermore. @Smithy, do you know a solution, or someone who can help?
  7. Hi, if you're talking about plastic of the "wrong" kind, that's where it shouldn't be, you could try using a prime tower (in Cura: settings -> dual extrusion -> enable prime tower). This helps priming the nozzles and wiping oozed material before it can contamine the print. Regards
  8. I'm glad we could help 🙂. Happy Printing
  9. Hi Balshaj, see this official instructions: https://support.ultimaker.com/hc/en-us/articles/360011474120-Lift-switch-calibration or, if you prefer watching to reading, a good video tutorial, privided by @fbrc8-erin: Regards
  10. Hi, is your print head fan (the one in front under the white flap) running? In this forum, non working or blocked fan often was the culprit for problems you described. Regards
  11. Hi, I bet you're using Cura 4.9. The missing prime blob #2 was a known -and actually solved- bug. Switch to the actual version of Cura (4.9.1) 😉. Regards
  12. Some aditional thoughts for your FW update: after you restored 4.3.3 and (re)started the update process, the UM3 will be updated to a version 4.x.x., which is only a stepping stone for the 5.x versions, as you already noticed. From this 4.x.x. it will (automatically?) install the actual version, which works well. The only issue I noticed when installing it (right when it was released) is an issue displaying the used material in the analytics section of cura connect, which is promised by Ultimaker to be fixed in the next update. Regards
  13. Hi Oscar, you possibly need to "unbrick" your UM3, but that's no hard matter and should easily be done. There're some useful posts in this forum, as or the very useful page of @gr5 mentioned in one of the last posts of o.g. topic: http://gr5.org/unbricking/ Here is the "old" unbricking procedure by Ultimaker, which is withdrawn by them, but still may be valid in my oppinion (but I deny all responsibility; I never was forced to unbrick my UM3, so my knowledge is only second hand and hearsay): 567519794_WorkInstructionsUltimaker3firmwarerecovery.pdf the
  14. Hi, you could try to clean the printcore-contacts of the printhead with a cotton swab and alcohol and perhaps reseat the plug of the printhead cable. Possibly it's just a contact problem and no circuit damage. Regards
  15. Hallo Helmut, ich hab' den Grundbeitrag jetzt nicht verfolgt, aber beim Thema Lüfter mußt Du unterscheiden zwischen dem Druckkopflüfer (der unter der weißen Klappe an der Vorderseite) und den Bauteillüftern (rechts und links am Druckkopf). Der Druckkopflüfter läuft automatisch an (oder sollte es zumindest), sobald ein Printcore die 60°C überschreitet und geht nach dem Druck erst aus, wenn beide Printcores unter 60°C heruntergekühlt sind. Einstellmöglichkeiten gibt's da soviel ich weiß nicht. Die Lüfterrate, die im Druckermenü und in Cura eingestellt werden kann, betrifft meines
