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"... 😞

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?

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.

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...

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...)

This mystery is gone after I did another firmware upgrade to v. 3.7.x. I still have no clue what happened, but am glad I am in business again Thanks to all for your ideas, I very much appreciate that!

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?

Two days since posting without any reaction, is it time to get really nervous now? Anyone care to help me out?

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 3.6.3.20170406 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?

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?

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?

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?

Hi Bas, To me this sounds like the bed-leveling system making tiny Z-corrections constantly. The same thing (though not as imminent as in your case) kept me confused for quite some time before I could pinpoint it. There are some other threads around this subject that you can go see, f.i. https://ultimaker.com/en/community/33351-knocking-sound-while-printing .

No they haven't been released yet, but I believe they will be made available to the public somewhere soon.
