    ... we think its getting caught up at the exit point into the Bowden tube. I'm currently looking to design a new housing with a metal guide rather then a plastic guide.


    Hi anxjfarnoth, what type of filaments are you using? You are talking about the tiny gap between the driving wheel and the place where the bowden sits? I thought that might be an issue only with flexible filaments.


    I used "tried" to print with PLA(proper UM filament), Ninjaflex, alloy 910 and nothing seemed to work, and yes that's what I'm talking about. the hole has already showed elongation and you can see a clear lip on the back side of it.

  2. Hi @Kris, @Pilzefreak, @travis-womack, @larsgw, @anxjfarnorth,

    I understand you had some issues with your Ultimaker 2+ feeder and what I understood from reading your posts you all shared similarities with a ticking sound coming from your feeder and under extrusion?

    If not, could you describe your issue in a DM with me.

    In that same DM, I want to ask if you could share with me if you have an Ultimaker 2+ or if you upgraded your Ultimaker 2 with an Extrusion upgrade.

    If you have an Ultimaker 2+, could you share with me your serial number, and a date when and where you bought it?

    We'll look into some data and may ask you to send us your feeder so we can look at it and send you a new proper feeder so you continue 3D printing.

    Looking forward hearing from you, and our apologies for any inconvenience caused.


    I had the Ultimaker 2 with an Extrusion upgrade, and I sent my printer into UM here in the UK and they replaced the feeder and got good prints from it for about 6 hours and when I got it I got about 1 hour and it started doing the same thing before. (please contact Alex at the support desk he is very knowledgeable of the situation) we think its getting caught up at the exit point into the Bowden tube. I'm currently looking to design a new housing with a metal guide rather then a plastic guide.

    I glued my plastic half's together to prevent it from splitting like above, I didn't hear a massive clicking sound I cant put my finger on the sound I heard. the only cure to fix my underextrustion was to go back to the original UM2 feeder.

    I find it odd that I had two bad feeders and everyone else is having good ones........this was really hurting our business as well having a printer broken for 3 weeks. (I love UM printer but I want to join the club with the new working upgrade!)

  3. well printing is better then not printing, I'm already in contact with support and they will be raising the issue to UM in the Netherlands. I think the fix is a metal sleeve that will slide into the Bowden tube and help guide the filament into the start of the Bowden tube rather then that plastic guide they used.

  4. Check out my hardware problem section, I did the same thing and after 9 hours I got this as well. Its a pain and I even sent my machine back to UM and they changed the feeder (I changed every possible thing) it worked for them for 5 hours and sent it back to me and I got about an hour of printing before it started doing it again.

    we(myself and UM support) think this is a feeder issue, you are the second person I know to have this same problem. keep me posted of what you are doing.

    good luck!


  5. I do have the Olson block installed and I have cleared out all of the filament from the nozzle. I have also tried printing with the new nozzle and that did not help. I have cleaned out the feeder and checked all of the motors and they all seem to be working fine. How would I go about checking to see what temperatures the sensor is actually reading? And thank you for your time Nicolinux


    Get a digital thermometer and touch it to it. My fluke meter has one. As for the PTFE that is very much a thing but mostly when you have printed at super hot temps for ABS or CPE for long periods. But they do wear out often so have a stock of them. My first one lasted me 800 hours......I was lucky haha

  6. Hey @Harish,

    If the filament doesn't move, you can unscrew the nozzle and see what's up with it. Heat up first (menu advanced settings -> maintenance -> heatup nozzle). If the filament pressure is not released, then you could disassemble the feeder at the back of the printer (don't forget to turn down the nozzle temperature).

    In order to disassemble the feeder, unscrew the two screws on the left side and the back of the case from the motor cover


    Then hold the feeder motor and unscrew the four screws from the black feeder.

    About the filament spool - you should contact the Ultimaker reseller in India and show them photos of the bad filament. I think they will replace it.


    He has a +....There is a lever on the feeder if you heat up the nozzle and lift up the lever you can pull the filament out very easily.

  7. yeah ABS is a tricky one, I make a glue slurry and that works most of the time and using a raft. so smear some glue down on the glass good and thick then take a wet cloth and run it over the top to make it wet and a very thin layer of glue/water mix. then set the bed temp to 60 and let it dry on the glass and that works for me about 10 prints. other people talk about making a acetone/ABS slurry and i hear it works wonders but I have never done it. I always try to keep things simple.

  8. how many people are having feeder problems with the upgrade? I upgraded my perfectly good machine and now have a very expensive paperweight and not even UM support can figure it out. I got about 9 hours of printing from my upgrade before I got under extrusion. sent it all back to UM and they replaced the feeder and got about 6 hours of printing sent it to me I got about 1 hour and the same thing. I'm thinking of throwing my old stuff back on and shipping back the mess that was sold. (when it did print the prints were lovely! just wish it could print longer then 6-10 hours)

    (I am not an amateur at this so if you mention it I have done it)

    UM makes a great printer I hope they figure something out as I'm 3 weeks soon to be 4 weeks behind schedule.
