    Well - to our luck is the quoted part "insanely inaccurate" to say the least...


    There's no 'key" or any kind of encryption - what he was complaining about was: the firmware updates are "signed" by Ultimaker with a certificate.
    The latter is IMHO a good and necessary thing for binary files that the printer receives via its internet connection (and the signing is hardly related to this topic).

    It means that nobody can plant an unsigned firmware on the printer with a man-in-the-middle attack. Oh-well - is this really a bad thing? 🤷‍♂️

    You have physical access to the printer, so who cares?

     

    OK, the "Digital Factory" / "Cloud" stuff is not Open Source - but that's what the API is good for.

    The Marlin part is Open Source software and the Linux part is accessible in developer mode and open as well.

    Not much that holds you back from developing your own firmware - or to modify the active leveling procedure (e.g.).

     

    I've modified an UM3 in the past, because i don't like the print core illumination and the loud 'beep' of the button. Was pretty easy. Just take the time and have a look (in developer mode) - it will be worth it.

    Ultimaker kindly provides recovery images, just in case something is screwed up. 🙂

     

    For some more insights from the firmware developers use the search term "Inside the Ultimaker 3". It's a few years old, but the principles are still valid. There are 6 articles (though the links  between them are broken since the forum software was updated...)

     

     

    Odd, my reseller parroted the same thing as the post when I grilled them about it. Guess there's one way to find out for sure. I'll poke around my own machine. Still without the marlin profile (configuration, configuradion_adv, etc) provided in its uncompiled form they're not making it easy compared to the 2, which has its entire marlin build on git

    Wait a second... just out of curiosity (i don't own a S5):

    Why not? One can develop and install a different firmware at any time, the hardware is not "locked" as far as i know.

     

    There's even a special developer mode which makes it possible to change and debug a lot of the (Python-) procedures without the need for re-compiling. There's a lot to explore.

    And each printers provides an API for "remote control" (actually two - the older one for network printing and the new one for the digital factory).

     

    Was anything of this removed in newer firmware versions? That would be indeed annoying... Or is it just because of the risk of losing warranty or such...?

     

    Quoting an earlier post about this by neotko
    "Yea your reseller did lie. They are ‘open’ up to a point but they don’t share, for example, the firmware build or how disable the firmware key (to easily build your own firmware)

     

    Without access to the firmware any hardware mod will be pita since um3/s3 doesn’t allow to easily force other gcode and that means that even the heating sequence (bed, core cartridges) can’t be changed."

    So yeah the hardware is locked but even if it wasn't I've got no base to start on, due to the source code not being available.

    Hi, we absolutely don't think our users are stupid and they have access to plenty of useful features and configurable options. As Nallath also added to the discussion a few comments above, there are also other reasons active leveling is recommended. It does not only compensate a flat horizontal offset, it can also compensate for a curvature. 

     

     

     

    But you dont give us access to the most important features, like being able to compile and load our own firmware. Something all of your previous models allowed us to do (Except maybe the 3 I skipped that generation)
    That reeks of "we dont wanna deal with RMA's from stupid people who brick their machines"

    I cant think of a single valid reason as to why you'd do so other than that. Stop protecting me from myself, I paid $10k for this hardware and it's mine. Let me use it how I want

    That is a nice quote, it doesn't really apply but I get what you are trying to say. For the most part, you can use the machine how you want. We have an open filament system, you are not bound to our slicer or preconfigured profiles and we've also been quite supportive to various modifications. But as I said earlier, we intend to offer best of both worlds between reliability and flexibility. Reliability is often taken for granted, until it is gone. 

     

    What error message are you getting regarding the NFC? Your profile says you have an Ultimaker S5 Pro Bundle, but if you have a Material Station, you shouldn't be using an NFC spool holder, right? 



    Considering half of the materials on the marketplace aren't supported by the material station it's been acting primarily as a $3500 drybox. I primarily print with ASA, PETG, PLA+, Zytel and only the pla+ works with the material station because I'm using a duplicate material profile based on generic PLA.

    And no it absolutely applies. "but sometimes this means taking a little bit of freedom away for the exchange of reliability and security." reads like "Our users are too stupid for us to give them access to anything actually useful" which is pretty much how Apple treats its users vs pretty much everyone else. The last 2 firmware updates have actually removed features I was using. Why dont you release the source for the S5 firmware so I can put them back myself and fix a few other major irritants? It would keep me off of the forum at least.

    but sometimes this means taking a little bit of freedom away for the exchange of reliability and security.

    Reminds me of a quote by a famous American paraphrased "Those who trade freedom for security deserve neither"
    Just use whatever defaults you want but let us use our machines how we please! Honestly I could fix half of the issues with my machine myself if I had more access to the firmware. Every update seems to break how I use my machine (latest introducing an error when I leave my NFC spool holder unplugged because most 3d party materials don't fit on it anyways so I made my own)
    and its getting super old.

    Greetings All,

    We recently purchased a S5 Pro bundle and I am in the process for getting it setup, received it last week. I have some questions about how the material station behaves and I haven't been able to find answers in the manual or the forum, so here goes.

     

    I just had my first NFC fail -  this seems be not uncommon - after a bit of mucking around I understand I can safely set the filament type during loading to a generic version on the printer interface. My understanding is that the generic material settings are the same as the ultimaker materials by default.

     

    My question is, if I have two of the same filament spools loaded (Ultimaker PVA) and one has the NFC fail, and has been set to generic PVA. What happens when the active PVA spool runs out? Will the printer treat them as the same? Loading the other spool and contimue with the print. Or will it throw an error and wait for me to do something?

     

    My next question is, what is the difference between having the spool identified via NFC and entering the material type manually? From what I've read, other than making things simpler by identifying the material type, it only keeps track of the amount of filament remaining and the colour of the filament. Does the NFC have any other functions?

     

    Finally, do any 3rd party filaments - I am thinking of materials alliance products - use the NFC tags or are the materials manually entered?

     

    Thanks for your help,

    Robbo

    It wont change over unless the second spool is manually set to generic as well. What I do is take the NFC tag off the spool and manually tape it to the left side of the holder. That's worked 100% of the time for me. Only ultimaker materials come with NFC tags I'm 99% sure. You just select the type of filament after loading it for 3rd party

    attached is something printed in yellow Esun PLA+ 

    standard Draft mode in cura, no changes at all.

    filament was dried for 8 hours first.

    I've tried that. no changes. And I've also tried multiple rolls of different colors so not a bad batch. Been working with my reseller for a while on this and they're stumped as well. if PLA+ was the only issue I was having I probably wouldn't say anything, but even first party materials have issues, different issues but still issues. ABS warps no matter what I try, even taping the machine up etc

    I have an entire laundry list of issues separate from this, maybe suited to a new post but im pushing my reseller hard to just return the machine outright and get my money back.


    I rebuilt the motion system this weekend, cleaned it and re-lubed according to instructions. Made triple sure my belts were properly tensioned, and printed out parts (in PLA+, on a Prusa) to make sure the axes were properly aligned and the made sure pulleys tight against the frame. I managed to eliminate some slop on the x axis but it made no perceivable (or measurable) difference in PLA+ or other material behavior/quality.

    I'm no novice to FDM printers, I own a literal dozen. Most of which I've built myself either from guides or kits. I even have a few high end SLA machines.

    This has been the printer from hell for me, nothing I try seems to make it work like I need (and expect for what I paid) to. I have $200 printers sitting on my desk that consistently produce better quality parts at a more reliable rate. Every time I interact with this machine I'm having to fiddle with it to make it work. Even materials downloaded from Cura marketplace have issues across the board. Ultimaker Tough PLA works (when it adheres to the bed, most of the time it doesnt without adhesive) and PVA works (When it doesnt break off inside the material station and make me tear the entire thing down because the push method isnt working)

    Oh and week 1 the mainboard had to be replaced entirely because my X axis stopped working. If I cant get my resellers to refund me I'm going to make them send a new unit, then its going straight to ebay to be someone else's problem

    Honestly, I would retry the print with some quality filament. I have never tried esun, but we had some users with similar problems in the past and as soon as they switched to another brand, it worked. 
     

    You don't have to buy UM filament, use some other quality brands, but not the low cost Chinese ones.

    You keep saying the material is trash when it works flawlessly on all of my printers except the ultimaker. Had I had known it wasn't able to print esun pla+ I never would have bought it in the first place

    Well, I should really reconsider buying the big Ultimaker. The support does not seem to be worth the cost.

    I wish I could return mine. The machine isn't worth the money if it was half the cost. Avoid. Wait for S6 and then watch it carefully before pulling the trigger.

    Hello together,

    I've installed the latest firmware at my S5 Pro Bundle and wanted to know how the light of the material Station can be switched off now. The only way I found out is telling the printer to activate the lights only when printing. Then everything is off. Just switching off the printer isn't eanough I think.

    Thanks for your help and best regards 

    Frederik 

    It's tied to the frame light simmer/slider. Just lower that all the way and the material station as well as the main frame light will dim, then turn off.

    Interestingly I have a new bug now, where the lights wont turn back on the material station until I reboot the machine. It's not that big of a deal but like.. come on I expect better QA than this on a $10k+ setup.

    After installing update 5.7.3. my UMS5 wouldn't start.

    It hangs with the Ultimaker name in the display.

    After a reboot of the UMS5 there is noithing changed.

    What could be the issue and what brings me the solution?

     

    It would be great to turn down the light of the material station 😉

     

    Grtz.

    Robbert

    You powered off the printer mid firmware upgrade? 😬
    You're gonna wanna reach out to support

    is this only with esun PLA?  does it work fin with other brands?

    I only had the ultimaker spool it came with to test and it worked fine. I've managed to get rid of the problem by upping the wall count to 8 and printing no higher than .015
    I think my specific issue had more to do with part geometry than material

    The use of the material station in the manner you describe is not the intended use case, it was not designed to switch materials that often. The switching would be super slow(due to the depriming which allows the material to still fit trough all the Bowden tubes and couplings after printing) and because you may have 10.000's of switches which will make the likelihood of failures during your print fairly high.

     

    In conclusion, doing this every couple of layers would be unfeasible.

    There is also no way to do so in cura.

     

    I admit I could hack some gcode together that does this anyway but this is intentionally undocumented and not selectable from Cura.

    If one were willing to take their chances, what would be a good place to start? I have a palette 2 pro that uses a fancy cloud based post processor to add the filament change calls to the gcode after slicing. Would it be a similar process to that, just adding gcode to call the de-prime and change function between color changes? I just need to know my starting point and I can probably figure it out from there.

    I admit it was my bad for not researching well enough before hand, but at the price I paid I assumed (again 100% my fault) this was a built in feature to what is otherwise a $3000+ filament holder with a dehumidifier. If I could get this to function for even just 4 color changes I'd be set

  14. I was able to sorta work around it late last night by just upping my wall count to 10. Uses way more material but even at .02 it prints OK. I discovered the same thing though, at .15 it's fine but that adds a LOT of print time to a fairly simple part (doesn't even need supports). Very strange. I wonder why this system is so sensitive to part geometry.. my creality printers never had an issue making the same part

  15. I tried starting with the main PLA profile as well as the tough and upping temps, I got it working ok before the X axis stopped moving mid print and my reseller provided and walked me through replacing the mainboard. As of this latest board I cant get it tuned at all starting to wonder if I got 2 lemon boards in a row 😕

  16. Does anyone have a material profile for Esun PLA+ for the S5 they'd be willing to share? Try as I might I cant seem to get it tuned right and get a moire like effect whenever printing below 100% infill. Same material works fine on my other machines, just not the S5 😕

    I've seen reports of others having issues too (just not mine) with eSun PLA+, is this machine just not capable of printing it? That would definitely be a deal breaker for me

  17. Ah... I really regret setting up my new S5 pro bundle in my bedroom.
    Can we get a +1 on this feature? It's 10pm I have 6h left on this print and I cant sleep because I bought a $10,000 lamp I cant turn off apparently. going to tape some black trash-bags on the material station to try and get me through the night 😴
