  1. Right you are, learing by doing is the best way. And apart from small imperfectoins one suffers on first try it is alway exciting if something new you try turns out more or less like imagined before. This encourages to try more and even if it fails you know so much more about how not to do that this is even amazing. I have no clue about Mario Kart trophies but for me done from scratch you did a great job.
  2. Ok, I'll give it a try to post something in this thread to keep it alive. We will see if this does make sense for the future. Latest project: Casting mold for a rubber seal for a mast of a sailing boat. We did this before but by covering a milled core with layers and layers of natural rubber. Problem was that this material is not UV stable and starts to get brittle over the years. So as a new trial we decided to make a mold and to cast this from 2K Silicone based rubber. Unfortunately the dimensions of the mold exceeded the building space of the UM2 to it had to be divided in parts. 6 parts
  3. jep, Robert and Foehnsturm that is always the problem when somebody gets the pin in his head that something well running has to be improved. In most cases no improvement but confusion. Really a bad idea not to offer a "latest first" sort option. For me also annoying this top bar going always up and down when scrolling the forum list with mouse wheel. But... it's their decision - I'm only a dumb user. They can to with their forum whatever they like to do of course and I also realize that there's no development without improving but for me it was somehow disappointing. I also see that at any c
  4. crappy bullshit... doesn't work. I would also bother to buy for spares as I am not sure if quality is r8
  5. Sander, thank you very much. Now we have clearness. Keep up your good work. Still love the printer!
  6. nallath, thank you for your open words. Is it possible to condense what you wrote to the answer of a simple question: Is a dual extrusion add on/upgrade kit for the UM2 still planned and coming from Ultimaker or not? I think the community appreciates all the R&D work but it is time for clear yes or no, so everybody knows what up and that's it. Thank you!
  7. not yet, I don't like to talk something being a bug but here I really have to ask how to fix. Did anyone got in touch with the guys making the Slic3r? If there is a guy in charge to talk to I'ii give it a try
  8. sure that the feeder isn't moving at all? We have similar problem here and recognized thet the E values are only very small. In your code you can see also a small value : G1 X89.409 Y90.985 E0.00593 F1260.000 . We have E-increments from line to line of about 0.007 hat is nearly nothing if compare to the code Cura generates under same settings with increments of about 0.5 from line to line what is about 71 times more. The UM2 does this hyper small increments usind the Slic3r code but of course it seems thet the extruder isn't moving. Any idea what might be the reason for this?
  9. looks really great. That is what tech pioneers do! Keep on!
  10. Woofy, the capton sticks like hell doesn't it? Could u tell a bit bout which material and settings u used? Look like 0,2 mm layers, r8?
  11. very good, IRobertI good idea for my next car :mrgreen: ... will keep this in mind
  12. Lennart, I tried to do a heat treatment to coils and I found out that it is possible to take out the tension by putting the coil into kitchen oven at a temp between 35 and 45 °C for about half an hour. This works fine for me.
  13. hey very good lookin stuff. Can u share a bit what material u used for print and what type of postprocessing u used to get the finish?
  14. ok, I see... nobody is going deeper in the dual extrusion theme as nothing usable is on the market yet. So no need for tinkering.
  15. öffne mal im Cura die expert settings unter dem Reiter Experte. Da gibts in dem Fenster, das dann aufgeht oben rechts unter Support die Einstellung Structure Type. Die kannst do von Grid auf Lines umstellen. Ich nehme an, das ist es, was du wissen wolltest, oder?
  16. Es hilft ungemein, wenn man die Minimierung der Druckzeit bzw. Maximierung der Geschwindigkeit aus dem Fokus nimmt. Gute Ergebnisse erzielt man zwischen 30 und 40, je nach Teil, Filament usw. gehts auch bis 60 noch ganz ordentlich, darüber wird's langsam so, dass kleinste Probleme grosse Auswirkungen auf das Druckergebnis haben. Der Grund liegt darin, dass mit zunehmender Geschwindigkeit auch mehr Material pro Zeit extrudiert werden muss. Das heisst, dass alle Funktionen in kürzerer Zeit stattfinden müssen, also Verfahren, Drahtvorschub, Aufschmelzen, Retracten usw. Damit wird die Harware schn
  17. ich habe mich auch schon gefragt, ob Ulitmaker die hat für sich extra machen lassen, oder ob das irgend so ein Standard Teil wie von einem Bilderrahmen oder sowas ist. Hab ich leider bislang auch noch nicht rausgefunden. War auch für mich nicht soo wichtig weil ich noch keine Ersatzteile brauchte
  18. jep and they came out pretty nice. Good job! But here we have dome larger details big kurved surfaces etc. This is very good for manual grinding, sanding whatever. At smaller pieces it can be a bit more tricky to get smooth surfaces by hand. Possible of course with some exercise.
  19. oh, nice shape! Did u design by yourself or did u find somewhere online?
  20. yep I think this vid was the reason why I wanted a tumbler :-P
  21. jep, can confirm that parts look similar after my tumbling experiments. I did no use steel stallites etc. but 6mm plasitc cones consistig of epoxy filled with some abrasive quartz. I have to to more tests. If possible it is worth to think about designing a part suitable for afterprint tumbling
  22. cheap chinese tumblers are runnin for bout 50 to 90 EUR on ebay. You can go much more expensive but for first trials these are good. Ok if DIY is the goal (what it should be :-P ) then you should start tinkering tonight... I thought about buliding one by myself but then I ended up building a vibrating sieve for my father's backyard. And this thing is running like hell!
