  1. Thanks for the update! Can we expect a blog post/forum post/etc. with a complete changelog for the 5.4.27 firmware update? I can't seem to find full documentation yet and was hoping to see if there was anything in it that might have fixed or adjusted the flow sensor errors people seem to have been getting on the last few firmware images for the S5.
  2. Ah, good catch! I had taken those off to put in a new tube (was hoping it would help with a separate issue, but alas it did not) and forgot to clamp them back on when I was done. I’ll make sure I double check stuff like that before I take a picture the next time lest I confuse anyone, haha!
  3. As someone who works with both UM3's and UMS5's (but who hasn't gotten their hands on an S3 yet), I have a few thoughts. As someone who does not work for Ultimaker and thus cannot know when or if such a kit would be made available, take them all with a grain of salt. The main improvements that I think you would be able to see from an S-line upgrade kit to the UM3 are all a result of the improved feeder assembly: the lever on the S-line models is a vast improvement over the thumb button on the UM3 in terms of user experience, the hardened version of the knurled knob in the S-line al
  4. @Smithy, your reply is correct and I think fairly comprehensive in regards to the Support Blocker function in Cura, but I think the OP speaks to a real problem: for something this simple and straightforward, there should never be any reason for a user to have to resort to forums to figure it out. In my experience, Ultimaker documentation has been decent, but there is always room for improvement. If there are ways we can make the user experience of the Cura software better or more intuitive—especially for tools that are front and center and will likely be explored by any curious use
  5. From the video, I don't actually think the first part of the level (with the Print Core in slot 2) is successful. It appears to be fairly far still from the print bed. In the active leveling process, the printer first measures and makes sure that the height difference between the nozzles is correct and then measures each part of the bed against itself to level it. To do this, the bed is raised until it touches the nozzle and it sets off a capacitative sensor inside the print head assembly. If the bed is too far away and doesn't touch the nozzle or trigger the sensor, the active leveling can no
  6. It's tough to say for sure, but I can see a few things here that might contribute: It appears that one of the magnets on the cover with the front fan is missing (see toward the bottom of the photo). I don't remember the exact dimensions of the magnet, but your reseller (3dgbire) should be able to source some for you. The plastic parts on the main print head assembly look a little worn (likely from all of the times the front panel has fallen open). It is possible that they are worn in such a way or that the metal pieces they attach to are bent in such a way that they no longer secur
  7. Interesting indeed. Even if there is a higher charge, 3mm seems like an awfully far distance for the sensor to trigger. I'm afraid I haven't encountered that particular issue you are describing before (nor do I use 3D Lac), so I don't know anything for sure. I imagine nothing has changed recently in your working area which has its own electric field that may interfere? If I do hear anything, I will be sure to let you know. In the meantime, if you find that wiping down the plate works or you come across any other solution, please do give us an update! I am sure it would be helpful t

    This is the first 3D model I ever printed and I was and am very proud of it. A few months ago, I started working in a university library makerspace. I had never worked with or used 3D printers before, so I felt a little in over my head. In the week before I began, I brushed up on research about what makes a good 3D model, how to sculpt objects, etc. I ended up downloading a sculpting app called Forger on my iPad and spent about six hours one afternoon shaping a sphere into the shape of this fox head over many iterations. After a while, I got the hang of it and it felt conceptually
  9. NBull said just about everything that needed to be said above. I would also recommend looking into low-friction holders to help heavier spools fight against other feeding issues that could lead to grinding. Ours was 3D printed and assembled well before I started working here, but I am sure there are similar setups available for purchase online. Here is a picture of our setup (using only Print Head 1 on a UM3):
  10. I just did a bit of work this past week to fix a UM3 that was having similar issues. My first recommendation is almost always to start with a manual bed leveling, but it sounds like you've done that already. Kudos to you! In any of your tests, does the plate press the nozzles into the print head at all (as opposed to just lightly touching them)? If so, it may be a faulty connection with the sensor wires in the print head. There are two wires behind the print cores (red and white) which connect to a capacitative sensor board via contact springs to sense when the nozzle touches the
  11. My first inclination without seeing any other information about your setup is to say that the bed is starting a bit too far away from the nozzles for the printer to compensate for the gap, hence the message that it "exceeds realistic values." The first thing I would try is to manually level the build plate once to at least get things in the right range (The gear tab on the left of the screen > Maintenance > Build Plate > Manual Leveling). If you have the calibration card that came with the printer, this should be pretty straightforward; the printer will walk you through th
