  1. 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

  2. BOnjour à tous je m'ennuyait un peut alors j'ai modifier le petit compagnon l'ultirobot pour lui intégrer des tirroirs très joli et pratique pour ranger cartes sd et autres "petits" éléments tels que les buses par exemples... hauteur de l'ensemble 20 cm... Fermé Ouvert J'attend vos remarques... pour ma part c'est en cours d'impressions

  3. Well tiny update. So far the 'springs' on the head where on a bad positioning that caused a leak because the white teflon isolator changed the angle. The solution (I should have think of this first) was easy, just by moving the springs directly on the upper part of the wood, so the isolator it's always being pushed onto the peek). Like this: Also used a third spring on the back screw to help with stability. The head it's printing like a charm, after 12h prints no leaks and perfect prints. I'm also finishing a better hangar, so it can be removed and used as one need's it. Without any amer

  4. I am currently testing the E3D V6 Hot End on the Ultimaker 2. I have created a mount and modified the firmware to allow for the use of the thermocouple and heater block that comes standard with the E3D V6 Hot End kit. I was able to carry out the Autotune PID for PLA and ABS in Pronterface for the ED3 V6. Using the change material function on the Ultimaker 2 allowed for the extrusion of the PLA as expected. However, a problem appeared when I went to print a simple test object. The system heated up and then before it reached the final temperature for printing the system shut down and the sc

  5. Goedemiddag! Ik ben Marcella van den Burg en werk bij Ultimaker. Ik ben hier verantwoordelijk voor het onderwijs. Ik kom op de meest inspirerende plekken binnen het onderwijs, waarvan ik soms het bestaan niet eens wist ;)Zo leuk!! Met de printer onder mijn arm bezoek ik leerkrachten om ze enthousiast te maken en te informeren over de wondere wereld van 3D-printen! Wil jij mij helpen om het Nederlandse onderwijs 3D-print klaar te maken? Deel dan jouw schoolprojecten en lesmateriaal via de Ultimaker community met je collega leerkrachten. Je hoeft alleen maar een profiel aan te maken (kost mi

  6. Have you checked the pulleys are tight on the shafts ? are the short belts nice and tight (motor's not lose) ? Are the limit switches actually being activated when the head is in the home position ? you should here them click if you move the head by hand to the home position ?

  7. Mit dem letzten Satz kann ich maggiman nur recht geben. Das hätte der Standard im UM2 sein sollen und nicht diese tolle open-source Eigenkonstruktion für die es dann nichts gibt und die man dann teuer verkauft. Hab meinen Block aus der allerersten Charge, und eine Menge an Düsen dazu. 0.8 für Holz ist zb. richtig cool und extrem stressfrei. 0.25 habe ich nun schon ab und zu für kleine drucke aus Bronze/Copper genutzt, schon extrem was man damit machen kann. (Figuren die auf ein 1€ Stück z.B. passen sind auch immer ein Hingucker. Und wenn eine Düse eben mal richtig versaut ist fliegt s

  8. Hi Kpk, did you already find help? Let us know how you are doing, hopefully you will be back on the 3D Printing track in no-time! Thanks,

  9. @anders olsson Hi Anders Many thanks for your excellent video. You have a fine technique of measurements. I know, mine has to be improved and is at the moment below scientific standards. There are a lot of interesting informations in your video (e.g. the effective temperature in the nozzle ant the effect of the fans). The critical point seems to be (and is in my case) the small distance between the left corner of the "Olsson block" and the heater bracket. If i got it right (at 4'43" in your video), you rounded your block at this corner somewhat. I'm thinking about this too; it shoudn't ma

  11. This is my latest print: My newborn daughter gets relaxed when she's hearing music from the Vikings Tv Show (from History channel, if you didn't watch I highly recommend it). So what's better than printing her a Viking Helmet? Nothing It was printed with a bad spool of PLA, so it's under-extruded at some areas, and i changed the retraction settings so it's a bit stringy on the horns but who cares it's for the fun of it. It was printed with the awesome Olsson block with a .8mm nozzle at 0.3mm layers. Just took 6h30 to print! Link to print

  12. I have been using the new RSB nozzles for a few weeks now, and i have to say that they seem to perform even better than the classic 118 degree ones, even if it will need more testning. I can highly reccomend anyone with a Ultimaker 2 to buy a Olsson Block and the JET RSB nozzles.

  13. Also, ich habe den Olsson Block auch seit ca einem Monat. Hab seit dem die 0.8er Nozzle drin und bin echt erstaunt, wie schnell sich auch grössere Teile drucken lassen, da die Nozzle ja nur noch bei 0.8mm Wandstärke ein Mal statt zwei Mal 0.4mm aufbauen muss, dass verkürzt bei mir die Druckzeit um die Hälfte. Die anderen Nozzles habe ich noch nicht im Einsatz gehabt. Aber der Block ist die Investition auf jeden Fall wert. Keine Ahnung, warum UM das nicht gleich beim UM2 gemacht hat...

  16. This is a huge deal. It's happened to me. Heard of it happening to others several times in addition to frederik's experience. Each time, myself included, the poster just said to hell with the long post just composed and walked away in disgust. I would advise - copy your posts to the clipboard before hitting "post". I don't want to pile on with all the negativity and give things a chance to improve. I am trying. Unfortunately others have not and will not be patient. The UM brand is damaged, and the longer it takes to make corrective actions, the more sever the harm. It's very sad reall

  17. I made a new, more extensive, video of how the heater on my printer performs during various stress tests: 00:10 Ramping to 300°C, logging power consumption (about 23W for the heater) 03:20 Temperature closing in at 300°C 04:25 Heater block position (gap between block and fan cap) 04:50 Testing fans at 100% with at 260°C 06:05 Feeding ABS at 255°C 06:50 Testing internal nozzle temperature with thermometer 07:55 Nozzle vs. Block temperature at 260°C (internal=265°C) 10:10 Nozzle vs. Block temperature at 220°C (internal= 226°C) 10:20 Switching fans on 11:30 Nozzle vs. Block temperat

  18. 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
