Have not been able to test the 1000ma yet. The filament keeps getting stuck in the nozzle now when I try an atomic pull, resulting in a snapped of piece staying in the nozzle. Doing the extrusion speed test results in it failing at around 5mm3/s - 6mm3/s and last time even at 3mm3/s The 3Dprima filament is between 2,9 and 2,95. Edit: I also took the head apart and found a piece of filament still stuck in the ollson block with the nozzle removed

It's not an IPM coupler indeed. I tried re-assembling the head again and it works better now so there's that (the small gap between the steel coupler and aluminum plate stays, but that's really just because of how the steel coupler from 3dsolex is made). I also bended the fan shroud a bit so it isn't touching anymore so that works for now I guess. The next problem though is the one I seem to be getting the most. random layers that are underextruded. No idea what causes it This was printed with 3Dprima on 210C and a speed of 30mm/s. Also, I want to try labern's fan shroud, but I feel like PLA won't really work for that. Any suggestions?

I don't think it's the temperature sensor, because I've switched the ollson block for the original nozzle before. I DID get a heater error when I tried an extrusion test, but after that I move the fanshroud around a bit to make sure that it doesn't touch the nozzle anywhere. I didn't get the error with the print in the picture so I guess that's okay. I've been experementing with REAL pla (yes, REAL is the actual brand) now, got a spool of black and one of blue. It's indeed kinda difficult to see what happens on the print because it's black, but it shows underextruded layers and layers being inregular. I always print at 210C with a speed of 30mm/s

Heya I've been getting more problems again with my ultimaker 2. The only material I use is PLA. I've really had a tough time printing stuff (made a thread some time ago and the problems vanished for only a small amount of time). I had switched out my (then) new Ollson block for the original nozzle again, because the ollson block clogged super quickly for me and just generally extruded badly. Yesterday, I tried installing the Ollson block again, together with a new steel coupler, teflon couple and a I2K insulator, all from 3Dsolex. But alas, I'm still suffering from underextrusion after that. The nozzle head I put in was almost completely clean but it made no difference. I have the steel coupler twisted all the way down and half a twist back. As far as I can see, the nozzle doesn't touch the fanshroud either. This is the kind of result I'm getting. I've tried printing it hotter but that had no effect either. I've been starting to feel kinda hopeless with how many problems I'm running into :( Thanks in advance

Hello The knurled wheel on my ultimaker 2 came loose. The hex screw that holds it in place has become round so the key won't fit. I've asked at a hardware store what size it is (and replacements), but they said they couldn't find the right size. Does anyone know what size it actually is?

Alright say we're a few weeks further now. We replaced the teflon coupler and it seemed to have done the job? Till now. We have also replaced the nozzle with the replacement nozzle, and now with the Ollson block. two teflon couplers in 500 hours seems a bit quick to me. The latest thing I tried printing was on 0,5mm^3/sec on 0.04mm layers. On a side note, are the teflon coupler from 3dSolex longer lasting, because I do think i'll also order an I2K insulator.

I've tried the theories yes (i actually have an ollson block sitting here now, but I don't really want to place it in now if the problem was not the nozzle itself and we haven't found the actual problem yet. Most prints I did at 1.6mm^3/sec with the standard settings. I've the infill, outer- and inner shell speeds all on 0 now to just use the print speed and for the most recent tries I've put it on 1mm^3/sec. I've called my dealer and they were going to call ultimaker themselves but I haven't heard anything back so I'm going to call them next week again.

The last problem was with the code yes (no idea why that happend in cura but thank god it was just that). I tried fastening the bowden tube a bit better and change the rectration a bit. I made one good print that took 11 hours and after that it went back to what it was. Everytime the material also just gets stuck in the feeder (because it most likely cant push through), so the material grinds up and it can't retract when changing the material. I've also had two times today were it was grind up so much that when helping the feed back by pulling it, it just snapped, leaving the rest in the bowden tube. The teflon part had been drilled up a tiny bit to ensure that the material didn't get stuck on any edge or anything.

The room temperature really isn't a problem (it's under 24C now and the first week i had it, it was the hottest week in the netherlands this summer and it worked perfectly.) We took apart the feeder and cleaned it and also tried putting the tension a bit higher. None of it helped. The filament diameter isn't bigger than 3mm (we used around half a 1kg roll before it started acting up) Just now, my dad tried to reprint one of his parts and it actually came up with a new thing! It just makes a line straight to the edge (any edge) and goes back. The first time it happend it went to the front and also hit it before going back.

I let me 7 piece file run this night, only to be greeted by 4 pieces completed, and it ending with this the nozzle is clean because it's completely new and the nozzle gets hot enough (did that test and the filament already starts melting lightly at 170) I'm baffled. Would it be the feeder after all?

The filament went through the isolator without any problem or force and the nozzle seems to get hot enough

My dad and I carefully replaced the nozzle today. Tried to print few things, but with not much succes. The calibration test that came with the ultimaker was weak and ugly (broke off the poles with very little force). My own model seemed to go right until the end, and the second one already started with ugly and underextruded bottom layers. The teflon coupler had a small brim of dirt but we removed that. I really don't know what could be the problem anymore. The feeder??

I have not been able to disassemble the printerhead yet because of the whole warranty thing and I wasn't able to contant my seller yet, but I did try cleaning the nozzle more. When I use the atomic method, I don't pull any dirt out and I don't think I even need a needle because I can actually see the nozzle exit pretty clearly. But still it suffers from the same problem, just stopping with extruding or not even starting with any extrusion. I noticed a few times where material gathers on the exit of the nozzle. The feeder seems to work like it should though (sometimes it doesn't retract the material though, most likely because it's stuck in the nozzle, and I have to help it by pulling on it).

We've had it for around 3 weeks now. I'm located in the Netherlands, so I don't think that the filament would be a problem (next to that, the week I got it it was really hot outside and it printed just fine.) The filament also doesn't seem ground up. The black stuff seems to have been removed with the atomic method but I don't know if it's definitely removed. Also if my search was right, an Olsson block is a nozzle block where you can unscrew the nozzle ?

The motor doesn't tick and the problem is still here. It just stops extruding after a random amount of time.

I tried putting the temperature a little bit lower for the atomic method cooldown and now i get a tiny cone shape so that's something I guess

since a few days i have the problem where my ultimaker stops extruding after some time. I've tried doing the atomic method, but it didn't help. Now, i'm also not sure if I really did anything wrong, because when I pull out the filament when doing the atomic method, i don't get a coneshape, just this I don't know if that's also a sign of me doing something wrong or anything. The latest print I tried wasn't even able to make the outside ring, with the line being too thin to just being nothing.

Heya I'm trying to print a new object, but everytime the bottom layer looks like this I'm using the standard settings for PLA. I've tried setting the nozzle temperature to 220 and even the bed to 70 but it keeps happening. What could be the problem and what would be the best thing to try next?

Heya So I've only got my printer recently and it's doing pretty good! But now I'm trying to print a model I made and when I put it into Cura, it creates a few weird lines that stick out on the model. They're not support and that's what makes it weird Would there be any reasons why cura does this?
