  1. Ok, it seems the Heater-Cartridge's broken. Thank you anyway!
  2. Yes, I tried before reseting the machine. It didn't work.
  3. Hello everyone, I'm still unable to use my Ultimaker 2 and I'm really frustrated because I want to use it so badly. I recently purchased a PT100-B-sensor on Ultimaker online shop because the previous wire broke : the Ultimaker 2 showed me a message when I started it and so tell me the was a sensor problem. Since I change this wire, I don't have anymore message : youpi! The only problem I've got is the nozzle don't heat up anymore. What ever I'm doing, it won't go up to 25˚C. I checked the connections, I plugged it on the right position on the motherboard. I tried different things, I pushed
  4. Here is another photo. It seems to be the sensor cable indeed. There is a black mark on the heater cartridge and it looks fine. Here another view: I don't think it's come from the PCB connection, the cable looks damaged before this unmounting and the temperature got down during the cleaning when I was holding the nozzle with pliers. Thank you for you answer!
  5. Hello everyone, After doing the smartypants unmounting the nozzle, I damaged a wire of the hot end. So now, what ever I'll do, nothing will happen. If I ask the hot end to go to 250˚C, it will stay at 25˚C. Anyway, that kind of thing happens, but I need to change the wire and I'm not sure the one I need to buy : Is it this one : https://shop.ultimaker.com/product/62/PT100-B-sensor Or this one : https://shop.ultimaker.com/product/58/Heater-Cartridge I believe this is the heater cartridge because I have the temperature of the nozzle, but I can't heat it up. I just wanted to be sure before m
  6. Thanks for all your advices. Indeed, I made new tries using Nick s recommendations about the settings in Cura. I also saw this post and I downloaded the files. The recommendations are 250˚C for the nozzle, 110˚C for the plate and no fan. And it works! I need also the plate to be really clean, but I almost have no more problem with stickyness. Nevertheless, the print almost crash as you can see on this pictures : You can see at the 75% of the print there some under extrusion. To prevent a complete fail, I try to help the feeder, pushing manually the filament. As you can see, th
  7. Thank you S.Ki, those tests are really interesting. I met some troubles with ABS, I will try this kind of configurations and I will definitly quote you when I explain this things to my students.
  8. Thank you gentlemen, I've got plenty of stuff to try! :-) Yes, it's weird, maybe I should unscrew the hidden srew at the top of the feeder even if it seems to be already unscrewed at its maximum. I'm thinking about printing that kind of feeder to avoid the filament dust to be stocked inside the feeder as well. I will let you know how the situation will go
  9. Hello everyone, I'm meeting some annoying issue those days. I try to print some pieces using ABS on my Ultimaker2. But I've got this unbelievably annoying problem with the objects I try to print : they regularly start to dance with the printhead. I try different things : http://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide#nostick, recalibrate it as well, try different quality of impression... Times to times it's working but I had to throw away some unfinished pieces. But the other tricky thing I'm meeting is also, on long prints, I've got some http://support.3dv
  10. Unfortunately, I don't have this Nylon (yet). But I'll keep this in mind, the next bobbin of filament I get might be this one. I was quite in a hurry so I use another technique (should I call it the Francois Technique? :-P ) I unmounted the nozzle, but I keep it connected with the computer of the Ultimaker. Why? Because I don't have tool with the EXACT size of the screw which keeps the wires connected. Anyway, I hold the nozzle with some pliers and with the help of a screwdriver and a pin, I itch the material to remove it. When it's hard, I heat up the nozzle (up to 260 if ABS) so I can empt
  11. I tried with the different temperatures, with ABS and PLA and I think I made the things worst now. I did it like 20 times, and nothing seems to go out the nozzle. Is it normal I had to do it that much for no visible result? Maybe I do it wrong, I don't really know what is the better way to clean it, il PLA works bette than ABS to clean the whole thing. I saw alors the http://umforum.ultimaker.com/index.php?/topic/9928-korneels-method-for-cleaning-hot-ends-um2/?hl=atomic, but I won't be able to do it at my work place (the printer is not mine, it is the one of the office). Thanks anyway,
  12. Yes I automatically use "PLA" presets of the machine, but yes I didn't think about cleaning the nozzle. I'll try this and I'll let you know. Thanks!
  13. Hello everybody, I've got another issue with my Ultimaker and I have not idea why I do have this issue. I printed something with red ABS filament and it worked perfectly. But I needed to print other stuff in PLA. I have two bobins : Orange PLA filament, I received with my printer so it's from Ultimaker and it's usually working Blue PLA filament, from esun (esunchin.com) which is quite bad quality and I've got problems time to time. None of them seems to work anymore! Everytime, I've got some feeding issue and it's giving me this kind of results : I didn't change any setting. It wo
  14. It's more or less the distance between the material feeder and the printhead when it's at the front right of the machine. Since you can't print without tube on the Ultimaker2, you need to have a tube about that long. The other solution is not to put anything on the very front right of the boardplate.
  15. Yes they did! Received on saturday, thank you very much for the tips!
