  1. hi It is not easy to machine because the material retracts easily. I tested successfully with pla and xt-color. but I have to do more tests. Tomorrow i test nylon and abs with more temperature. I keep you informed .... I have to sleep. :wink:
  2. hi, I think I found the solution to print more than 260 without burning the coupler. I have made a coupler in Duratron. working temperature 310 ° C. Here pictures of my first test with pla. http://umforum.ultimaker.com/index.php?/gallery/album/1478-glloq/ I've also tried it with no problem with XT ColorFabb color. I have to do more tests. see you soon. :-P
  3. hi, Now I have my coupler in Duratron. :cool: Here some pictures of my first test with the pla. http://umforum.ultimaker.com/index.php?/gallery/image/10272-pbi-duratron-coupler-um2-310%C2%BAc/ http://umforum.ultimaker.com/index.php?/gallery/image/10273-pbi-duratron-coupler-um2-310%C2%BAc/ http://umforum.ultimaker.com/index.php?/gallery/image/10274-pbi-duratron-coupler-um2-310%C2%BAc/ http://umforum.ultimaker.com/index.php?/gallery/image/10275-pbi-duratron-coupler-um2-310%C2%BAc/ http://umforum.ultimaker.com/index.php?/gallery/image/10276-pbi-duratron-coupler-um2-310%C2%BAc/ http://umforum.ultimaker.com/index.php?/gallery/image/10277-pbi-duratron-coupler-um2-310%C2%BAc/ with ColorFabb XT color also doing well. working temperature 310 ° C I have all weekend to try. :-P
  4. if you try to put a flexible filament in an original UM2 feeder, you will see that the filament passes behind the wheel of the feeder, because there is no guide. The flexible filament always escapes by this empty gap. This part prevents this, and the filament stays in a good position.
  5. hi, I just published a modification of the original feeder UM2 to use flexible filament. The explanation is in French, but it is so simple that the pictures explain everything. https://www.youmagine.com/designs/um2-part-for-original-feeder-for-flexible-filament With the filament Taulman Bridge or PA6 filament work any good. I have not tested the NijaFlex.
  6. Salut Je viens de rajouter des photos du feeder original modifié! https://www.youmagine.com/designs/um2-part-for-original-feeder-for-flexible-filament
  7. hi, I'll try to make a Celazole PBI coupler. Does anyone have the technical scheme of the UM2 PTFE coupler? Thanks!
  8. @3Poro There are other materials that can be very interesting. Celazole PBI is also an excellent thermal insulator. Other plastics in melt do not stick to PBI. These characteristics make it ideal for contact seals and insulator bushings in plastic production and molding equipment. Highest mechanical properties of any plastic above 400°F (204°C) Highest heat deflection temperature 800°F (427°C), with a continuous service capability of 750°F (399°C) in inert environments, or 650°F (343°C) in air with short term exposure potential to 1,000°F (538°C) Lowest coefficient of thermal expansion and highest compressive strength of all unfilled plastics With a more affordable price. 12.70mm Celazone Pbi Rod,305mm Length, Duratron Pbi Rod > £129.18 or 161 euro http://www.plasticstockist.com/Duratron-PBI.aspx With this you can make 14 coupler > 11.5 euro per coupler !!!
  9. @3Poro hello! Thanks for your information Where did you found the vespel 1/4 "diameter part, to make your mixed vespel ptfe coupler?
  10. Attention ne pas utiliser de la colle forte pour bloquer la vis de la molette d'entraînement. Je galère pour l'enlever, j'ai mis de la Loctite, grosse erreur. :( Utiliser plutôt du teflon liquide.
  11. Now I can compile the firmware for Ultimaker2 !!! :lol: Thanks Daid !!!! Works following the steps Daid says but with the Arduino version 023 http://arduino.cc/en/Main/OldSoftwareReleases At the end of the compilation we can read the path of the Hex file: example C: Users (user name) AppData Local Temp build2111424711106922953.tmp Marlin.cpp.hex Note: To delete data lines twi.c file, download Context free software, in google.
  12. It is right that says Daid !! > You need to modify C:\arduino-1.0.3\libraries\Wire\utility\twi.c (remove the file, or remove the SIGNAL(TWI_vect) function at the end of the file) or else the UM2 firmware will not compile. I have a compilation error with twi.c. LIBRARY I follow all the steps exactly and finally got this compilation error. Error compiling! Wire\utility\twi.c.o: In function `__vector_39': C:\3DPRINTER\arduino-1.0.3\libraries\Wire\utility/twi.c:364: multiple definition of `__vector_39' UltiLCD2_low_lib.cpp.o:C:\Users\YO\AppData\Local\Temp\build8630848773746948483.tmp/UltiLCD2_low_lib.cpp:181: first defined here c:/3dprinter/arduino-1.0.3/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/bin/ld.exe: Disabling relaxation: it will not work with multiple definitions If I delete or modify the library twi.c I have another kind of compilation error. Note that does not exist in Library twi.c SIGNAL (TWI_vect) fuction but ISR (TWI_vect) fuction Error compiling! Wire\Wire.cpp.o: In function `TwoWire::write(unsigned char const*, unsigned int)': C:\3DPRINTER\arduino-1.0.3\libraries\Wire/Wire.cpp:195: undefined reference to `twi_transmit' Wire\Wire.cpp.o: In function `TwoWire::write(unsigned char)': C:\3DPRINTER\arduino-1.0.3\libraries\Wire/Wire.cpp:177: undefined reference to `twi_transmit' It is possible that these steps works with the Ultimaker firmware, but with the ultimaker2 I think there is something missing ???
  13. A suivre ici aussi (En anglais) http://umforum.ultimaker.com/index.php?/topic/7710-print-more-than-260%C2%BAc-with-a-um2/
  14. UP!! @Daid Hi Daid, thank you for your advice. I do not control the C language I tried to delete the file twi.c but I get an error to compile the firmware. This is what I find when I am looking to code (TWI_vect). Which part of the code I have to eliminate? I have version Arduino 1.06 // update twi state twi_state = TWI_READY; } ISR(TWI_vect) { switch(TW_STATUS){ // All Master case TW_START: // sent start condition case TW_REP_START: // sent repeated start condition // copy device address and r/w bit to output register and ack TWDR = twi_slarw; twi_reply(1); break;
