Ok, it seems the Heater-Cartridge's broken. Thank you anyway!

Yes, I tried before reseting the machine. It didn't work.

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 the wires (sensor and heater cartridge) to the very end of the holes of the nozzle. Nothing seems to heat at all. I tried also to reset factory presets and now I'm stocked because every time I start the printer, it proposes me to insert material. So I had to wait the nozzle to be hot, but nothing happen. Where can the problem come from? The nozzle? The new wire? The connection? I send this to the support, I'm waiting for an answer, but if anyone of you got the solution, I'd be really grateful. Many thanks,

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!

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 making a wrong order. Here it's how it looks: Thanks!

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, there even is a part which hasn't been printed at all. I took the pictures just after the print. So if you have any idea about why, I'm interested into your advices! I launched a print this week end and the nozzle seems to get blocked. Honestly, I have no idea why. Could it come from the fact there is some dust into the feeder which come to the tube then to the nozzle? I feel a little bit despaired due to the fact this kind of things happens every time the print duration start to be long. Thank you!

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.

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

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.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide#grinding. I met different cases mentioned 3dverkstan, but it keeps happening. Sometimes I can prevent it when I'm around, helping the filament to go inside the feeder with my hand. But the printer is at my office and I mind a little bit staying 18 hours long for some printing just to be sure nothing will happen. I'm getting mad because when the first layers stay on the plate, most of the time the filament stops after few hours. Following http://umforum.ultimaker.com/index.php?/topic/10005-working-w-abs-but-not-w-pla/, I try to clean as much as I can the nozzle, so I don't think the grinding is due to a clogged nozzle. So if you've got some other explanations for those problems or some tips to prevent them, I had to say it could be really useful because my researches haven't been effective. Thank you!

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 empty the rest of the material. Following the mounting of the print head, I do the atomic method couple of times to be sure there is no more residue left inside the nozzle. I really feel like MacGyver sometimes, but who doesn't when you've got a 3D printer :mrgreen: But THANK YOU GUYS! I started to print something and it seems to work quite alright! You were right

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,

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!

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 worked with ABS, then I put PLA. PLA didn't work so I put back ABS then it worked again and fail again with PLA. When I go to the "Move Material" option, the PLA pops out the nozzle. I have no idea why it does that. Any thought? Thank you!

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.

Yes they did! Received on saturday, thank you very much for the tips!
