    CPE+/PVA -> awful warp

    Also, I am not sure if it has anything to do with the water. I submerged it immediately together with the glass plate. Maybe it is just the temperature shock.
  4. CPE is a little more heat-resistant than PLA (up to 70°C), CPE+ is said up to 100°C (I've not used CPE+ so far, only CPE), but with water temparature up to "hand warm" (starting temp, no heated bath) i never had problems with after-print warping.

    CPE+/PVA -> awful warp

    thanks - but wasn't CPE supposed to be more thermoresistant than PLA?
  6. Nein, oberhalb der Mitte ist weniger Federspannung, je tiefer die Anzeige, desto größer ist die Federspannung (siehe z.B. hier: https://ultimaker.com/en/resources/52504-clean-the-feeders) Grüße

  8. Hi, I've read somewhere at the Ultimaker-Homepage, that the water used to dissolve PVA should only be up to 30°C, but they recommend use of cold water. Greetings
  9. 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!
  10. 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.
  11. Apparently the new firmware has only affected 1% of the UM users. Could we hear from the mute 99% that were not affected?
  12. Danke, ich beobachte die Sache und melde mich gegebenenfalls. PS. Die Feederspannung war im oberen viertel. Oberhalb der Mitte ist doch strammer oder? Gruß
  13. 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?
  14. 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 😞
  15. Anyone selling or know of a S5 for sale in the UK ? Thanks
  16. 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
  17. 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.
  18. No i updated after actrually as i assumed it could be that.
  19. 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.
  20. 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)
  21. The other thing you can do to help is to lower your flow rate for the first level by 20-30%
  22. 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.

  23. Well I'm definitely interested. Email me at pringlekeara@gmail.com.
  24. 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?
  25. 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 😉
  26. I just threw all my money at the screen, did any of it arrive? 🙂
