  1. Extremely disappointed about the extremely high price set by Ultimaker for the CC Red core. In my view that kills all viable and reasonably priced options for using abrasive materials on a UM3. Add to that the fact that Cura only allows selection of this core for the 5S, and it is clear to me that Ultimaker is no longer that open source / community driven and loving company anymore.


    It hurts to say this, but Ultimaker has just lost a great deal -if not all- of my sympathy as these recent marketing actions from Ultimaker are nothing short of a big ""f**k you" to customers like me who have purchased a UM3 in the very recent past and are now being told "sorry, we have no future for your new printer anymore"... 😞

    All Bondtech feeders are based on the same types of drive gears which grab the filament from both sides. The gears are made from hardened steel and have a protective coating (you can read it e.g. here: https://www.bondtech.se/en/product/drivegear-kits/). So it is very wear resistant. In case you want to print a super abrasive material and the Bondtech gear would show some wear-off (which I doubt), you could replace just the gears, it's available as a spare part.

    I never had a problem with my Bondtech feeder, it's very reliable. And the good thing about the DDG is that it is a drop-in replacement for the Ultimaker 3/2+ feeder.

    As for the new core I just used it in connection with the S5 feeder so far and for a quick test on the UM3 with the original UM3 feeder (which is ok if you don't do it too often).

    It seems there is no Bondtech reseller yet in the Netherlands but e.g. in Germany you may find multiple ones that are also Ultimaker resellers.


    Thanks for the information @Dim3nsioneer , I missed that page. I was not expecting a vital piece of information ("Extremely high wear resistance for use with abrasive filaments") being missing on the regular feeder webpages ? ).


    Certainly worthwhile considering to get me a set of those.


    And nothing wrong with ordering in Sweden direct I would think, would it?

    @Zwakie The new CC 0.6mm RED print core together with a Bondtech DDG V2 feeder for the UM3 might be exactly the bundle you need.

    What country are you in?


    I have visited Bondtech's website, and though it looks promising at that price point I am surprised nothing is stated about wear and tear when using abrasive materials. Do you have first-hand experience with that combo and do you care to join your experience with us?


    BTW I am in The Netherlands.

  4. Thanks @SandervG for your reply. I was kind of expecting exactly that answer, so my next question was already in my mind yesterday: does Ultimaker not wish to increase customer satisfaction by making the feeder available for their UM3(+) customer base? In my view that would be a perfect way to create commitment with customers to follow Ultimaker's future path...

  5. Thanks for the information Sander, this opens the door to this question that most UM3 owners will have I would htink: will the new CC core work on a UM3(+) and will the S5 feeder be made available as an upgrade for the UM3+)?


    I for one I am very interested in using composite materials, but I cannot justify upgrading my entire UM3 for a S5 just to be able to print composites every now and again (I do have a need for that from time to time though...)




  6. What if you do a manual leveling to get the build plate closer to the nozzle and then attempt an automatic leveling?


    Thanks for the suggestion, but I have already tried that before posting it here (FWIW: I have already tried all options available).

    The only way that I can get the bed to close vicinity of the nozzle is when I raise the bed using UM3's menu. All other options leave me with a huge distance, effectively rendering my machine as inoperative.

    Any other suggestions, anyone?

  7. I am hoping the collective wisdom here can help me fix a problem that surfaced after upgrading the firmware of my UM3 to the newest firmware today. During the upgrade I noticed the motion controller received an upgrade as well. New f/w version is

    The issue I am having is that the distance of the build plate to the nozzle is well over 10 mm, which simply is too much to compensate for by the screws when leveling the bed. As expected, the Z-axis offset calibration did not bring success.

    It does not seem to be the limit-switch since I an raise the bed (using the printer-menu option) to within a couple of mm's of the nozzle (with screws fully tightened).

    I am lost on how to correct this, any ideas?

  8. I don't think I'm allowed to say anything.  :(

    Probably not your intention, but your remark adds to the uncertainty, as I feel this is an "in the eye of the beholder" type of comment.

    Anyone from Ultimaker care to provide clarity about expected availability dates for the new cores?

  9. I can't really tell from the picture, my guess is that setting "Z Seam Alignment" (in Cura, under Shell) to "Random" will help (with this model setting this to "Back" will probably only move it to another place on the model)

    I would also try reducing the amount of oozing happening at start or end of printing a line. Maybe the experimental option "Coasting" can help as well?

  10. I had problems a few times getting the UM3 to print a model using only the second nozzle.

    I did not yet investigate this to find the root cause, but my gut feeling is telling me there is a little snag in Cura, since I never have an issue when I select the first printcore for bed adhesion.

    Again: this is a proviso observation. Maybe others experienced the same?



    Did you ever find out what is causing the noise?

    Yeah @fbrc8-erin, it definitely is the bed-levelling after all.

    As I wrote in my last reply, I had given the idea that the sound lasted throughout the entire print, which was not the case. Apologies for the confusion, but thanks for asking!


    I'm sorry, it looks like I missed the last response. I was reading the earlier one where you'd mentioned the clicking being ongoing. Glad to hear it's working well!


    Your helpful responses make up big time for being sorry about having missed a detail ;) Thanks again!

    Hi, I'm looking forward for the possibility to get into 3D Printing with this combination of the Ultimaker 3 and ColorFabb like filaments, with metal, so I'm looking forward for the solution...

    It took me some time, but i get it to work :-)

    If you want to print with two "foreign" Materials (as a dual print) and do the workflow Zwakie suggested, you'll get the following message from your printer: "This print job is not suitable for this printer - Err 26"

    So the printer will NOT start the job....

    What you have to do is to cheat Cura and the printer :-)

    In Cura you have to pick up for the printcores one of the 5 Materials (eg. CPE) and modify it in the section "Material" on the right side - like printing temperature, build plate temperature a.s.o. so the it has actually the parameters of eg. Bronzefill. When you select the material on the printer it has to be the same you choose in Cura (eg. CPE).

    It's not working when you add a new material to the list in Cura and select that for your printcore and slicing - then you'll get the ERR 26 message.....

    hope it helps,



    Good additional explanation @Conny, and funny you mention the E26 error since tonight for the very first time I got that error. Unloading the non-UM material and reloading the same non-UM material cleared the error for me (it felt like the UM3 got itself confused somehow, since I can't explain why this fix would clear the error).

    Despite that, things for you seem to work a little different than for me since I have been using non-UM materials on both print cores exclusively for the last weeks without any problems. Maybe a small detail was omitted from the workflow that I wrote down, but despite a careful re-read I don't know what it might be :(.

  13. But does it shrink or deform?  


    During printing it does indeed shrink, so you have to watch out for warping. @Artiz and myself have been 'playing' with Polymaker PC-MAX recently and shared experiences in this thread: https://ultimaker.com/en/community/22722-polymakers-pc-max-polycarbonate

    The purpose of 1 hour annealing @ 100C and subsequent controlled slow cool-down to room temp is to relax the material. What this does is slowly reducing the internal stresses caused by the melting/solidifying process (which is what we do when we print the stuff). In fact this process is not making the stuff stronger, but instead takes away internal stress so that the printed piece will not deform afterwards due to these stresses. So if you need the dimensions to remain unchanged long after printing, you will need to go through this process (of course, heat above glass temp will still deform PC).

  14. You can simply ignore the warning and go ahead with printing.

    I did all the things you discripted above on Cura / Printer. When i got the warning on the Printer and tried to ignore it, the Maschine didn't started the print!!!! That's why i began this conversation....

    I see... I had the exact same thing once, it happened when I did not follow the normal material/printcore unload/load sequences all the way through the end (I did not -and still don't- fully understand the logic behind the differences of unloading/loading materials and printcores so I was experimenting a little to find shortcuts here ;) ).

    My fix was to go through the cycle (one step at a time): unload material - change printcore - load material.

    I think that during the fix I just broke off the second step after it accepted the 'new' printcore by powering off the printer, but am not 100% sure about this so could be that I did follow the full sequence presented by the UM3.

  15. So what to do now??????

    Hi Conny, it's not a real big deal, you only need to find your way around Cura I guess.

    For material that is not recognized automatically because the NFC tag is missing on the spool, you will have to setup a material profile once (remember: having a profile for different colors of the same materials can be helpfull).

    How I do this?

    1. On the UM3 itself select the closest match (temperature wise) to the material you are loading; temperature is important so the 'unknown' material will melt properly

    2. Open Cura

    3. On the menu go to Settings > Printcore (choose number you have loaded material into) > Material > Manage materials...

    4. Duplicate material profile that most closely matches the material loaded and name it so that you recognise the material

    5. Edit the newly created profile to match the material parameters

    Next step is to create a custom print profile via Settings > Princore [x] > Profile > Manage Profiles, this is pretty much self-explanatory when you go through the screens, basically works the same as for setting up materials profiles. Before doing this give a bit of thought of how you will name the profiles, since the list of profiles might grow large over time and a bit of smart naming might help you find profiles a little easier later on.

    Once you've done this, you can select the material through Settings > Printcore [x] > Material and the print profile through Settings > Printcore [x] > Profile

    All that is left now is set the other parameters for desired/optimal print results (most likely you will need to a bit of test printing to get to the desired result), and update the print profile when your requirements have been achieved.

    In case you wonder why to setup materials AND profiles: setting up materials independ from profiles allows you to use the same material different profiles.

    Hope this helps.

    Edit: I forgot to mention that when you start a printjob via the network, you will get a warning that material does not match the material that Cura thinks is in the printer (remember you selected one of the 5 available on the machine itself?) You can simply ignore the warning and go ahead with printing.
