  2. Something horrible happened. I made a large Ultimaker CPE+ print, and it came out of the printer beautifully (build plate: 110°C, UMS5 with plexiglass cover to retain heat). Then I put the model into warm water (45°C, thermostat + pump) to dissolve the PVA. And now the model warped horribly! It seems that the surface that was against the build plate has contracted and is now all bent. However, the upper surface (opposite to the build plate) is still in shape. What could have happened? How can I prevent that? Any help would be very gratefully accepted!
  3. Today
  4. How many users have provided feedback on this upgrade? How many % is needed before you consider it relevant? I regret that you consider opinion from minority not relevant.
  5. Apparently the new firmware has only affected 1% of the UM users. Could we hear from the mute 99% that were not affected?
  6. Danke, ich beobachte die Sache und melde mich gegebenenfalls. PS. Die Feederspannung war im oberen viertel. Oberhalb der Mitte ist doch strammer oder? Gruß
  7. Hello, Hope this is this correct place to post, So my UM2+ has been sitting for a month and when I went to level the bed the rear thumb screw is soooo tight I can only move it about 2mm each way so i can not get the bed level and I don't want to break something whats the best why of freeing up the thumb screw so it will move like it use to?
  8. I'm printing everyday with UM3 and since the upgrade to firmware 5.2 the active level doesn't work anymore. In fact I even got scratch on the glass plate because the nozzle was touching the glass plate (through an UM adhesive tape !!!) The factory reset doesn't help. Hopefully I can still use manual level. As described in this forum I can't downgrade the firmware 5.2 😞
  9. Anyone selling or know of a S5 for sale in the UK ? Thanks
  10. Je viens de remettre mon UM3 en fonction, j'en ai profité de mettre le firmware à jour et cura à la version 4.0 Au moment de l'impression, elle a fait une calibration du niveau.. tout automatique. Est-il possible de désactiver cette fonction étant donné que j'utilise plus le plateau en verre mais un support en métal de Gegotek et que cette fonction de calibration (lancé par le menu à l'époque) ne se terminait pas bien
  11. I've never had anything other than 1.75 filament near this printer; nevertheless, it's something that crossed my mind so I checked the label as well as measuring the filament itself just to be sure.
  12. No i updated after actrually as i assumed it could be that.
  13. Hello @Mozella, if you use 2.85mm filament and, somehow, the old Cura thought it should be using 1.7mm filament, that would probably account for it. Just guessing, really.
  14. On the Printers pane of the preferences, go to Machine Settings and change the bed shape back to rectangular (you seem to have somehow set it to elliptical)
  15. The other thing you can do to help is to lower your flow rate for the first level by 20-30%
  16. I upgraded to 4.0 from 2.7 and now my prints start to far from the build plate. I go back to 2.7 and everything prints fine. Below is my first few lines of gcode: can someone tell me what I need to change to correct the issue.

  17. Well I'm definitely interested. Email me at pringlekeara@gmail.com.
  18. Bought an UM3 couple months ago, and the transition from higher-end hobby printers to a printer I trust ... just amazing. Earlier this week a print with colofabb nGen went wrong long enough to goop up both print heads with nGen and require me to remove them and clean them off. When I put them back, the bed was out of level and autolevel wasn't helping, so I did the manual level and tried to do the XY calibration but either the print head would be pressed so tightly against the bed that nothing came out or it just wouldn't stick. Using the original UM green, did a cura connect reset, wiped my cura profiles, no help. So I turned all of the levelling knobs a 1/4-1/8th counter-clockwise and now I get prints but the first layer is bumpy and I get elephant's foot and curling, but mostly, part way thru the first player, the print head crosses and catches on something and the print starts to come undone (yes, I have combing and avoidance enabled, I reset to defaults) I'm wondering if the honeymoon period is over now, and if from here on it will only ever print as well as lower-end/hobby printers I'd had before, or if there is a guide to restoring that factory fresh reliability?
  19. Thanks 🙂 I guess it is on its way 😜 If you can send me your email address then I will get you early access and you don't need to pay for it 😉
  20. I just threw all my money at the screen, did any of it arrive? 🙂
  21. I've never found any way to get gradual support to build viable support, it never graduates between the original "lazy" support and the next layer up: Might produce something like this: I expected that the individual lines of support would be further apart, but instead it just seemed to produce half the support, leaving a whole half of each subsequent tier floating in thin air: (Yes, I've tried different patterns, concentric is where it is easiest to see when you are controlling the camera view) Anyway, this suggests to me I'm doing it wrong?
  22. Am I missing something or is there a circular mask on the print bed in this software? This severely restricts the area I can print on. Is this intentional? How do I disable? 3.6.0 did not have this limitation.
  23. Hi All, This is Baha Abunojaim CTO of Mixed Dimensions, the company behind MakePrintable. We are currently in the process of finalizing a new plugin aiming at enhancing Cura with features that will ensure print-ability and reduce the time and cost associated with a print, these are the features planned for the next release: Unlimited local repair of 3D files. Optimal orientation to reduce support and print time. 3D packing. Hollowing. We are planning to introduce also the ability to create advanced workflows from nodes directly from within Cura but I also want to reach out to you and hear directly from the community on what features and enhancements you feel critical to making your life easier and more productive. If anyone interested to beta test the plugin then please let me know.
  24. UM3 bed got out of level and I wound up making settings tweaks that didn't help, and now I'm trying to back them out, but as I scrutinize how the build gets printed, some of it is counter to my *novice* intuition. If you watch the first layer, it starts laying down the wall around the "window" panels and the speeds are kinda weird: then it makes an odd choice about where to start the next panel, resulting in a bunch of extra travel that could have been eliminated if it started at a different point: the order in which it does these next pieces is a bit puzzling too - in that it works left, bottom middle, right, center, top right, left, for all of which it only does half the lines. Then it does the outer perimeter in full before going back and finishing the window-walls; then it fills the rest of the face: and even then, it goes back around and puts more lines directly around each wall. The other issue I'm having is that there are weird patterns on the bottom surface because of the way it tries to fill the base resulting in a surface that (in a kind of cool way) has a panelized look, like an 80s starship surface heh. And whether I use lines or zigzags, the way in which seams form between the contiguously printed panels and resulting travel significantly affects the smoothness and rigidness of the bottom surface: the marked lines show up as clear seams/distinctive "panels" on the bottom surface: Is this where perhaps I should be using concentric? I gave that a shot and it had the same outlining wastage and then it did this: It seems a lot like Cura could have made things easier on itself if it had realized that it's dealing with a round/symmetric design? The resulting seams are actually kinda neat: But they still somewhat marr the finished surface which - went it adheres properly - is a beautifully flat, smooth surface. I've attached the print and the settings I'm using, I'd love any input on what I'm doing wrong and how I can produce a better print? -Oliver Insert image from URL spool.3mf spool.curaprofile
  25. Hello, I apologize ahead of time if this is not the proper place to post. I am new to 3D printing and Cura. I have an Ender 3 Pro and am looking a place to find guidelines and general settings for my machine to input into Cura. I know this is a loaded question with many factors to consider. Aside from the general info (bed size, nozzle etc.) what settings are generally considered best? Is there any other resource available? With the popularity of the Ender series printers, I'm a bit surprised there was not more to find. Thank you for any assistance. I searched the forum for "Ender 3 print settings" and found nothing. I will admit the format for this forum is not familiar, but I assumed my search criteria should have had some hits.
  26. Yesterday
  27. I've been using Cura 3.6.0 with Octoprint and a Tevo Black Widow for a while now. I spent a lot of time upgrading the printer and fine tuning nearly everything over a long period of time. Eventually I achieved near perfect results under nearly all circumstances. My rig is so reliable and versatile that I can't remember the last time I changed anything either hardware or firmware. However, three days ago without warning, the print quality became horrible. It looked like massive over extrusion, but to an extent that was so severe, that I suspected something else must be defective. The print nozzle was plowing through the print to a degree I've never seen before. My first guess was a Z axis fault. I checked the obvious mechanical things like set screws, belt tension, etc. I re-calibrated my Z axis and calibrated the Extruder as well........ all OK. Thinking it might be a driver, I did some driver swapping between a spare, the extruder, the Z axis and the Y axis with no change to the problem. I experimented with some settings and discovered that I could make a good test print if I dialed the filament flow down to 50%. What's up with that? It made no sense. I started thinking how could my printer suddenly double the feed rate without warning and without having changed anything. The fact that my extruder calibration was perfect added to the confusion. A year ago I had what I thought was a driver overheating problem which, after a LOT of fiddling around, turned out to be a defective main board, so I ordered a new board and a fresh set of drivers just to be on the safe side. I'd rather spend 50 bucks than spend another full day pulling my hair out chasing a mystery. While waiting for the parts I re flashed the Marlin firmware............ no joy. A few hours ago I upgraded to Cura 4.0 and now the printer is behaving perfectly, just like it used to do. I'm partly happy, but not completely thrilled because I hate it when things go wrong without explanation and I also don't like it when the repair doesn't make sense. I'm not sure Cura was at fault, but upgrading did in fact fix my problem. How could the older version of Cura suddenly double the extrusion speed? Or am I barking up the wrong tree? S
