  1. Birdfeed holder, to attach the bird feeder to the new small tree in our garden, with branches too thin, but with a 40 mm diameter trunk. Fixed with two velcro stripes. Filament is Nylon transparent from Ultimaker, construction with Fusion 360.
  2. Actually I am having problems with "Pause at height" also: After loading a model into Cura 3.6.0 I add a post processing script "Pause at height" or "Filament change" for a change at a certain layer number. When during printing the printer (UM3) reaches that certain layer, it goes to pause and I can change the filament. When I resume the print after changing the filament, the (travel-)speeds seem to be different (very high) and there seems to be no more z axis advancements. Is anybody being successful in doing this or could it be some Cura problem (or am I just plainly stupid)? I tried the "Pause at height" without changing the filament and it went perfectly fine...
  3. Not sure about that, because in this certain setup the horns are being used as tweeters, with low power input (the FRS 5 X drivers are suited for 5W). I think what you mean here is happening mostly for the lower frequencies with the airwaves transporting a lot of more energy, where material resonances can (and do) influence the sound. But a definitive answer would require some more measurements to check for resonance effects in the horn material. The horns definitely bundle the sound waves, which gives the speakers a very special directional characteristics (which I do not like).
  4. He left it as-is (and likes it). Regarding the layer lines effect of the horns, I just discussed this with a friend of mine who is a real analog audio guy and who designed and built the crossover network for the speakers (which turned out to be a real pain in the neck to optimize it) and did also a lot of measurements of the speaker system. In his opinion the acoustical effect of the layer lines is insignificant. My own tinnitus doesn't allow me to be an audio reference listener :-/ so I don't have an opinion on that.
  5. Thanks & have fun (see attachment)! 😁 Horn_4_3_v5.stl.zip (right now the guy who I made them for is offering the speakers @ebay: https://www.ebay.de/itm/Lautsprecher-Visaton-Gradient-prof-entwickelter-DIY-Lautsprecher/123572160771)
  6. Could somebody please have a look at this peculiar scaling behavior (see video screenshot)? When I rotate a model in Cura 3.6 and scale it in non-uniform way, then -- after the first non uniform scaling -- just by clicking into the scale value windows it changes object sizes in strange ways. I do not think that this is the intended way... please see video: https://drive.google.com/file/d/15S9pqEQmlUNl62u6c2E2yVKTOX-D4uT-/view?usp=sharing Thx, -pl
  7. That is not sufficient. Sometimes all you have is the STL file. (And yes, I know that you could import it into the modeling program, but it would be better to be able to measure distances within Cura. This would also be helpful in case you scale a model.)
  8. For me it takes 184 seconds.
  9. What about this for a slow startup on MacOS...?

  10. This is mine... brand new and up-to-date. And Cura 3.5x did run perfectly.
  11. Similar for me. On my 2018 MacBook Pro it takes about 2...3 minutes to start up, using 100% CPU. During this time it displays "updating configuration", before it eventually shows the GUI and becomes responsible. This behavior is reproducible. I guess Cura 3.6 needs some kind of serious tuning 😉 Btw., I like the Gyroid infill!
  12. Nice, about the same place as last year. I would like to get an impression of the S5, so that's a great opportunity. Any chance to receive a ticket voucher? Thanks, -pl
  13. Will Ultimaker be at the formnext 2018 fair in Frankfurt in November?
  14. Thank you, SanderG, for your kind recommendation, I respect your opinion. Anyway I just repaired it, my UM3 ist printing again. Wasn't so difficult, please see my photos and the description. Both of the wires connecting the capacitive leveling sensor are plugged into contact springs on the sensor, and the other side is plugged into a print head PCB connector. Obviously there is a design problem which leads over time to breaking wires at the sensor side, due to bending the wires when opening the print core cover for changing the print cores. If you want to repair the broken leveling sensor wires, you got to unscrew the four screws holding the bottom part of the print head. The bottom part then is only held by the level sensor cable and the front fan cable (the two middle connectors of the four ones). Disconnect both of them, be careful to not damage the wires while freeing them. Now that you have the printhead bottom part separated from the printhead, you can disconnect the wires (or remove the broken part of the wires) from the contact springs by carefully opening the inner part of the spring until the wire can be pulled out. Don't use too much force, the contact spring is very delicate! If you bent it away from the middle you gotta bend it back. You might wish to use a magnifier and a pointed tool like a needle for this part of the action. Un-isolate the ends of the wires and solder them, then plug them back into the contact springs, take care not to reverse them (see pictures). Check that they are tightly stuck in there, otherwise you need to bend the spring somewhat more. After re-assembly of the printhead (careful with the side fans and their cables) and inserting one or both of the print cores you can start the auto-leveling procedure and hopefully start printing again. Good luck!
  15. From my first exeriences with them they want me to ship the printer back to them. I don't want to do that, because I'm not sure in what condition my beloved UM3 will be returned to me. I would have better bought it somewhere else, but when I bought it I didn't know that. :-/ BTW., would be nice to have some kind of instruction for the printhead repair... (hint, hint)
