  1. A value of 1 equals 74 micrometers
  2. The printer always uses both nozzles for the bed level measurements. The first probe is done with the right nozzle, and then the printer probes with the left nozzle. The printer then checks if there is ~1.5mm height difference between them. If you always get the “exceed expected value” error, please look closely to what happens and compare it to what I just described you. Especially watch closely if nozzle switching works correctly.
  3. I suspect your print head control pcb is broken, such noise values are really really bad. Please contact support or your reseller.
  4. I advise you to clean the spindle again, and relubricate. A tiny particle caught in the grease can cause this. Move the bed up and down by hand and check if you feel irregularities
  5. In the past, the "skip cooldown" option enabled you to skip the wait for cooling down the print bed. This feature is removed, because the printer does not take bed temperature into account in the post print sequence. Users with a material station still have to wait for the deprime procedure, which takes quite long. This cannot be skipped.
  6. Make sure you are signed in your account when you use Cura (top right of your screen). If the blue button in the right bottom of your screen says “print via cloud” (after slicing) you are signed in. When you are sure you are signed in, you should select your printer in the list (top left of your screen). And then in the top middle of your screen you can select the configuration. If your printer has a Material Station, with multiple spools loaded, you should see multiple configurations to choose from. if you select one of these configs, the print job should start without hiccup when you select “print via cloud”
  7. The grouping is not coming back, I’m sorry to say. Are you aware that you can still print from Cura to every printer over LAN? And every printer still has its own local queue, but indeed, jobs will not be divided across printers. Does this help you enough? The video feed is still available over LAN. And reprinting is brought back in 8.1.2
  8. You're on a very old firmware version. You cannot update in one step to this version, you need a so called stepping stone version. I'm not too familiar, please open a support ticket on our website, or read the documentation that is on our website
  9. From this story, it looks to me as if something is wrong with Cura. why do you think it may be related to your printer?
  10. The file format has not changed for years. New firmware or a factory reset is not likely to help. Have you tried another USB disk?
  11. I agree with Torgeir, the heating element is certainly not mounted correctly. The element I circled in red should be fully inserted in the brass heater block. I'm sorry this core came to you like this, you can replace it with your reseller. It is a 10 second fix. Loosen the small screw on the bottom of the heater block, and then you should be able to slide the heater fully in the block. Then tighten the small screw again.
  12. The Ultimaker 3 does not support printing filled materials. Your nozzle will wear out very quickly (really, after 1 spool of XT-CF20 the nozzle diameter has grown to 0.6mm, and is has also shortened) But while a print core can be replaced, even worse is the damage you do to the feeder. The feeder wheel will not be sharp anymore after 2-3 spools. This will cause underextrusion with all materials that you print with.
  13. The UM2+ has normal steel feeder wheels. If you've been using Colorfabb XT-CF20 with it, there is a good chance that your feeder wheel has become dull (not sharp anymore). This may explain the underextrusion you are experiencing. All S-line printers have hardened feeder wheels since a few years (only the first version of the S5 did not).
  14. This is not true, it is a setting in the material profile. This should be tuned by the material supplier, they supply the profiles and we put them in the market place. The setting is not exposed in the front end of Cura. That is not to make your life hard, we make that choice because the deprime process is very hard to get right. We don’t think it is a good idea that customers start experimenting with these values themselves, that’s why we ask suppliers of the filament to do it. However, we still sell an open system, and if you want, you can. open your cura config folder (under help) go to the materials folder find your material profile and open it in a text editor find the line with break temperature Change it, and increase the version number of the profile (around line 15) Restart Cura, and sync the profile with the printer beware that your version will now be out of sync with what the supplier is doing.
  15. The materials that you have problems with are third party materials. Do they have a profile in the Market Place, and are these compatible with the material station? If you experience unloading problems you should ask the supplier of the material for help. Ultimaker gives (software) tooling to suppliers of filament that helps them create optimal profiles. One of the things that has to be tuned is the deprime settings. When you have ER61 issues, it may be due to a non optimal material profile.
  16. The amount is dependent on the previous material used. If a printjob is with the same material, there will be smaller amount of purging than when the printjob is with a different material. Purging is needed to make sure all of the previous material is flushed out, so that also when you change from black to white filament, you get a nice white part without a gray bottom.
  17. You say you have done 70 days or around 1700h of printing with this print core, and you use a 3rd party material with the default settings for PLA. I can’t explain why you have this clogging, I am sorry. I would not call a nozzle that printed 1700 hours new, however.
  18. It has been noticed, and it has a very low priority to fix. Because it is not a problem. It is just different.
  19. What brand of materials? Do you use the standard profiles in Cura? If not, what changes do you make? When you get a clogged core, what does the lifetime counter of the core say? (Can be found in “about this printer” I believe)
  20. This is simply not true. Tens of thousands of customers are happily printing thousands of hours with a single print core without any clogging. I dare to say the Ultimaker print cores are amongst the most reliable designs in the market. More than 5000h of printing is no exception. Printing with Ultimaker materials will give you this reliability out of the box. You are very welcome to print with other materials, but that may require some tuning some print settings. You have said multiple times now that you have bad experiences with PVA. PVA is the most difficult material that we have. It is however possible to print reliably. It takes dry filament and a clean BB core.
  21. I was told by colleagues that you should use the Griffin option, and assumed the M84 line would not be in there. I was wrong, I just tried it with in an internal newest version of Cura and the M84 line is still in there. Someone showed me a change in github that solves this, but apparently this has not been merged yet. I can't say when it will be released. The only option I have for you on the short term is to manually remove the M84 line from the gcode. By the way, Internally we have also found that sending the file via Digital Factory blocks the pause at height functionality. This is now an issue on the backlog, it should of course not matter how the file arrives at the printer.
  22. The end position of the printhead after filament loading has changed as an unintended side effect of another change. Although different, it's completely harmless, so I don't think it will be updated any time soon. Same goes for the leds in the printhead. Issues are noted on our backlog.
