  1. Same issue here. Thanks @leliep for your instructions. Those made it quite easy to fix it myself. I didn't put the wires back around the connectors (as in the 2nd picture of leliep) because that made the wires very tight.
  2. Same problem here. "Reset Cura Connect" solves it, but only for a while. This is how it looks in Cura And this in Cura connect: I also noticed that sometimes the printer asks me twice to confirm that I have removed my print.
  3. So it's clearly a bug in Cura. Thanks navigator for this work around.
  4. Today I tried to add a new material in Cura (via Preferences, Configure Cura, Materials). I duplicated the Generic CPE and then started to change some settings: Display Name: PETG Brand: BrandXYZ Material Type: PETG (doesn't exist in Cura) and then, as soon as I leave the last field field, the material has gone, without any warning or message. Another material (ABS) is then selected. At first I didn't notice that this happened so I entered several other values, but I was altering the wrong material! Unfortunately there is no Cancel-button on this form so I wasn't really happy. So please UM/Cura-team, - add a Cancel-button to this form - support unknown materials OR give a clear warning before throwing away my entered data OR make the Material Type-box a selection box. Thanks!
  5. Thanks to peggyb I looked a bit further and then I noticed another preference setting: Zoom toward mouse direction. That is almost exactly what I wanted. There is only one (smaller) annoyance: the zooming goes in big steps. I would prefer a smoother zoom-behaviour. But that might also be a problem with my Logitech mouse.
  6. Thanks for the tip. But selecting an object is not always what you want, because as soon as you select an object you also select an action like move, scale or rotate, and then you could accidentilly make unintended changes. So I still hope for an implementation of my request.
  7. Hi, I have a request for Cura. When zooming in or out, the zoom function always uses the center of the screen as the origin-point. Many other (design-)programs use the current mouse-cursor as the origin while zooming. That makes it much easier to go quickly to a specific point without having to switch between zooming and dragging all the time. You just point with the cursor to a point and zoom in to that point, just by using the scrollwheel. Inspecting another detail would also become very easy: zoom out, point to the other detail and zoom in. Thanks!
  8. Thanks @cjs for your detailed answer. Yes, I did print with the prime blob disabled. PLA works fine, but PVA doesn't. Even with the prime blob enabled the extrusion of the PVA sometimes starts too late. This usually happens when I have the PVA loaded but not used for a while. In such cases, before starting a new print with PVA, I move the PVA manually until it starts to extrude (you could call it a manual prime blob). As an extra assurance I also keep the normal prime blob enabled. If necessary I use tweezers to rescue my print from being hit by the PVA-blob. It's not ideal, but I'll deal with it. It's better then an unsuccessful print. I'm not confident to change the firmware code (at least not in the near future). And besides, that would be a task for the Ultimaker team.
  9. @Brulti, @gr5, @ghostkeeper, @ahoeben As you are using 'my' thread to arrange meeting I hope that meeting will be about the prime blob. Good luck to all of you, I expect a great solution.
  10. That's exactly why I like to use that prime-blob. @Daid Is it really that difficult to change the firmware so that after the prime blob is extruded the print head and print bed do not start moving together, but have the print bed wait a second (until the print head has moved away) before it starts raising? This would solve the whole problem.
  11. I'm using hairspray now for a while. This is an excellent solution for the PLA-prints, but it's not enough for the PVA-blob. I think the primary problem is the movement of the printbed that causes a collision between blob and printhead. That should be solved in the firmware and/or slicing software. All other solutions are just work arounds.
  12. I tried using glue but that didn't work. Perhaps PVA slurry will work (I didn't try that). But just grabbing the blob with a pair of tweezers seems an easier work around. I think the main cause of the problem is that the print bed is raised before the print head has fully moved aside. The collision between the blob and the print head should not happen. Of course there are several work arounds, including not printing a prime blob at all, but I would prefer a software change so that this collision doesn't happen anymore. Is this possible?
  13. Cura version is 3.1.0. Printer is Ultimaker 3 Extended with firmware
  14. Hi, I'm new to 3d-printing so I prefer using the standard settings of Cura. Every print starts with a prime blob. I guess that's ok. But as soon as the prime blob is ready the print bed starts raising at the same time that the print head starts moving. That causes the print head (to be more precise: the bottom of the front fan) to hit the top of the prime blob. If the prime blob is PLA then it just flattens a bit but it stays on its place. But if it is PVA then the prime blob often falls down and sticks to the print head. The print head then drags the blob onto the center of print bed, ruining the rest of the print. Request: Isn't it possible to alter the Cura-software (or is it the firmware?) so that the print bed waits a second before starting to raise after the print head has started to move to avoid this collision?
