  1. Hi guys, After years of following the evolution of the mark2 project, I finally got my hands on relatively cheap second-hand Ultimaker 2 (non plus that wasn't in the best shape to be honest) and did the upgrade a week after receiving the machine! As a UMO veteran - not even the Ulticontroller was around when I first got my machine xD- I am super amazed how well the mark2 does! While I have been playing around with the original dual extrusion upgrade, I must say that the mark2 is lightyears ahead in every concern!! I created a magnetic head for my e3d-hotend that I'll be sharing any time soon : As well as a basic blade-holder for a vinyl-cutter to mimic a design I found here: @IRobertI With all of this being WIP, I am looking forward to try the cutter as soon as the blade arrives and give the e3D Hotend a try (all cables on the second head are already equipped with molex connectors to enable a very quick head-swap)!! Update: Turns out, that the mark2 penholder is a much besser way to attach the blade to the printer, as it exactly fits the 11m diameter of Roland-like blade holders AND also holdes a pen firmly! I adapted the design by making is little longer and tried it on the printer just yesterday, as I am still in the gcode generation process, there are no pics or upload yet.. -> I'll update you soon! Thanks again to every one involved in the mark2 project, @foehnsturm and @tinkergnome specifically! Cheers, JI
  2. @neotko: I thought so, but never had an opperunity to try one Is this actually due to the fileformat of those SD-cards being incopatible with the ultimaker (so to say SD-HC vs Ultimakers SD-format) or is there any other reason?
  3. To be honest, i dont understand why some people actually fancy printing via usb... It is definitely not as reliable as using a SD-card. I received my Ultimaker(orignal) before the Ulticontroller was available and dont really miss that time to much xD Back in the days, Cura (or an other extra-software , that took pregenerated gcode) had to be used to send the commands to your printer. As already said, this connection was not as reliable as one would whish. I have no clue, if this was due to the Computer-Usb-stack not being designed for real time applications or the fact, that the Arduino in itself is not a Pc let alone a powerhorse, why you can actually it kind of lagging while going through the menu during mid-print. If you ask me, you cant really compare the Ultimaker, being based on standard (and relatively cheap) electronics, to a specialized CNC hardware, built for (just?) usb printing. Anyways, if you fancy a wireless solution, go for one of those cool wifi SD-cards some photographers are using. You can get them quiet cheap on the big A, but watch out about their fileformat, as I don´t know which ones will work (e.g. http://www.amazon.com/Share-Reader-Camera-Support-Micro/dp/B01BAQ0QAQ/ref=sr_1_1?s=pc&ie=UTF8&qid=1459024280&sr=1-1-spons&keywords=wifi+sd+card&psc=1) combined with the approach of auto-removing the printed part as in the “Autoprint” (https://ultimaker.com/en/blog/65-start-your-own-mini-factory-with-autoprints) , you could do your remote printing (and definitely don’t have to touch the card ), given that you find a way(e.g. a relay) to start the print, but as most people I would not recommend it anyways xD and forget about usb, belief us. Good luck and let us know what works best! Cheers, Ji11x28
  4. Hi Guys, after working on it some time ago, this thread makes me want to get started with my old idea of producing a similiar (but not terminator inspired ) robo head again! my robo-eye is already working quit well! Eexcept the motors and the short wire peaces (connecting eye-ball and motor) everything is printed! Movment is not to smooth which is mainly due to the bad servos i am using.. I already got replacement but as good as no time to work on the designe.... The brain of this baby is going to be a Udoo-Quad and i am planning on adding a webcam (or better to say just the chip) in between the eyes to get some object tracking implemented! Since OpenCV already runs on the chip and due to the arduino compatible IO-pins i could control up to 48 Servos what should be enough!! Since i am free on friday and after braddock posted the video, i am planing to get work on the subject done within the next days! If you want i can post my progress! Cool work braddock (amazing renders) and thanks for inspiring me to get back on my project Keep it up! Cheers JI
  5. Dont know if i am a pro but i am in london for an other week and might help you out with some of the things you mentioned! Send me a pm!
  6. Hi guys, I didn't find enough time just yet iam sorry... I managed to get things running with ct data and am not to sure if you'll be able to handle the specific ultrasounf format... Since the mitk-software is really komplex i'll need some time to finish the tut (and the pictures i was planning to use) Ji11x38
  7. He guys, Planing on 3d printing some stuff from an mri-scan next week. I am going to use mitk, the medical imagery toolkit. If anyone is iterested, i could write a small how to. I think you can actually open 3d ultrasound files but i dont know for sure just giv it a try! It's completly open source and free to use (made by the company i am working for!) Regards Ji11x38
  8. I have been contacting you via pm. Got no reply...are the any pulleys left? Or will. There be an other batch any time soon?
  9. Wow amazing ken! By the way are you italie ? For some strange reason i have never heared of the fist of the north star till living in london for a while and meeting many italiens. They all had in common, that they were always chatting about ken xD Anyway here is one of my prints: It' s one of my printed lampshades. Made up of three parts and printed in the amazing golden pla that is a bit translucent! It has a wonderful warm light!
  10. Hi there ! Didn´t read this thread yet but am a bit disapointed since there are so few pics at the moment... Printing with the dual setup seems to be more difficult than we all thought (and even more time consuming...) Did not have to much time to play around yet but here is what i got so far: The first one i did is this little guy here: with his low z-resolution he looks quite bad and as you can see, there are lots of troubles on the feeder of the red pla. In the context that the print took place before the kit was released (and a good number of changes in the software ) i am still impressed how well it turned out in the end. After contacting the ultimaker support recently and a great reply in form of some laser cut parts, i managed to upgrade to an almost official dual extruder setup. The only result so far is this calibration print i have been doing about 5 days ago: As you might see,i still got underextrusion on the red parts. After going through several other steps, I finally found out, that the printed Bertho-drive-upgrade i have been using so far was to small for the new wooden feeder-parts what led to the problems. In this pic you can see the old Bertho upgrade in my fully printed feeder (got the designs from Snowygrouch's web-site http://www.calumdouglas.ch/%20) After some thinkering, i managed to use the plans for the injection molded Ultimaker parts from youmagine (https://www.youmagine.com/designs/injection-molded-parts-for-ultimaker) and printed the new Extruder Drive Upgrade today, that can bee seen next to the old feeder. I am planning to give it a run at the weekend! I will let you now how things turened out!
  11. Thanks for the great pics ! Wonderful that you took the feeder apart! Really interesting what ultimaker did! And amazing that we got some fotos of the new z screw setup
  12. I was wondering how you generated the cad files. Am i right, that you "only" exported the files out of the video game? Or did you do this design yourself (or even for the videogame)? Sorry to be so rude... i am of course impressed about the work you did(especially on the color!!! Aswell as on the joints!!) I myself already managed to print some files out of Half-Life 2 due to reading the graphic-card memory. it would be interesting to see what you did! Anyway what you did, what where u using? Keep it up! Ji
  13. I would love to see a picture of the electronics or at least one of the bottom of the printer. Is the arduino gone or are they still using one? And what about the servo controllers? ( did you solve your layer shift problem yet? ) A closeup-shot from the new feeder would be cool,too! (Even better if taken apart) How did you put the tape on the print platform? Can you undock it somehow or did you have to fiddle around to get the tape on it? And last but not least: is their anything behing the motot covers? (Except the motors ) Did not see too much in the pictures you posted in an other thread. Thanks ! ji
  14. Thanks3dcase! You were right and everithing is running smooth now! Looking forward for the bank holiday to give the new setup a try! JI
  15. Long time no post... Returning to this thread with the need for help does not feel as good as it usually does. After being able to get the Dual Extrusion working on my own (the thread was a really big help ) a few month ago, i finally "upgraded" to the official kit. Thanks to Merrit the transition was almost painless as ultimaker sent me all the new wooden parts + the black injection molded clamp holder from the kit. The only thing missing at the moment are the two corrugated springs that i could not source yet. And that's exactly where i need the help of the Community! Has anybody any idea what kind of springs are used and where i might find them ? Found this on German Ebay: http://www.ebay.de/itm/10-Edelstahl-V2A-Nirosta-Din-137-Federscheiben-M6-/120772720420?pt=DE_Haus_Garten_Heimwerker_Eisenwaren&hash=item1c1e9d7724 It´s a corrugated spring for M6 (Id is 6.4mm and outer 11mm) think they might be right. What do you guys think? For those of you who where early adopters + live in germany (snowy?) this: http://www.ebay.de/itm/Schnellverbinder-Fitting-Steckverbinder-1-4-Zoll-Wasserschlauch-2Stk-SBS-/181165965447?pt=Wasser_Aufbereitung&hash=item2a2e554087 and that: http://www.ebay.de/itm/PTFE-TUBE-METRIC-6-35MM-X-3-17MM-PER-MTR-WORLDWIDE-SHIPMENT-/261277567268?pt=LH_DefaultDomain_3&hash=item3cd55b4924 might be of use! Looking forward for a reply! JI
  16. Thanks for the reply Ian, didn't realize the problems before you mentioned them! No clue why this happens since my belts are very thight and my axis are all oiled up, too. Thought that it might be due to the compresion of material as a result of the bowden setup. As you can see the "pillars" between the doors and windows in the front are quite thick compared to the rest of the walls. Which might be a result of an over extrusion effect after the minimal retraction the printer did,just before moving to the pillar. The part in the back left blackened as result of not using the fan at all. since i do not have a heated platform, i tried to minimize warping this way. Can´t say much about the speed since i started out with just 55mm/s and crancked the speed up a goog bit by using my selfmade ulticontroller I´ll have to see what i can do! But the Pla45 mentioned by gr5 might be a great idea + cheaper since if live in Germany, too!
  17. Thanks illuminarti ! Already had a look at the resources on their side. And found some stuff on youtube about zspheres that wasn't bad at all! How long have you been using ZBrush and could you show some of your work? I have already seen the stuff you did concerning 3D-scanning (of your familie if i am right) and the postprocessing you did in ZBrush. But one of your Designs might give a better impression on your work! J
  18. Put my Printer on the Desk as Danny. While the place seems not to be as dark as his Place, my Printer anyways got included light, too
  19. After Month of reading this thread, i finally want to show you some of my prints! First of all i recently found out about the OpenDive Augmented-Reality-Glasses and after taking a closer look on them at GamesCom Cologne, I had to give them a try: Check out there website on http://www.durovis.com/opendive.html and try them yourself! They are quite impressive for the 17euros you'll have to spend on the lenses! An other print i did was inspired by Ian who has been putting upo lots of his architectural models: it resembles my flat i am living in and should be my the first of many more models of this kind! @ Ian:what programm are you actually using? And how do you get so perfect windows/doors without support? Last but not least I´d like to show the project iam working on since i got the Ultimaker in February: My own Hexapod Robot (kind of but nowadays more like a Project for University..) Looking forward to get feedback! JI
  20. Hi Ultimakers, Since i found many People using Pixologic's ZBrush around here, I was wondering if anybody can tell me where to find usefull tutorials for beginners. I have already searched many threads and watched lots of videos but still am not to happy with my skills. Got to say that i enjoied the written tutorials more than the videos and would aswell spend some money on books about the programm (anyone read Introducing ZBrush 4 by Eric Keller?) An other thing I (and as far as i can remember Ian who opended thread about) would be voronoi structures! Since i am using rhinoceros and cant talk of great results, please let me know what you are using (seen cool stuff done using Blender) Looking forward, JI
  21. Don´t know what kind of software you are useing but rhinoceros can create such structures. but they are other ways to generate such voronoi structures. Google should give some more detail "voronoi" is the wayy to go!! would be cool if you could post your further findigs! Would love to give it a try myself! regards ji11
