    Aluminum build plate update

    in Official news

    Just buy a neoceram glass plate, cut to size and cheaper than UM parts. Also, from the point of view of giving 1 extra glass, it’s a bit of shameful. UM is aiming at pro market and can’t make their promises. I would understand that from e3d and prusa, but UM thinks of itself as ‘pro’ market. Ofc the buyers could make a legal use of the written promises and ask for more money than just a glass price. Just like what happens to any mayor market seller, if they fail they get sued, clear and simple. Ofc that didn’t happen when was the um2 and the promised second extruder upgrade because that wasn’t Pro market, but now?

     

    From the point of view of finding a good replacement I would buy a neoceram glass or vitroceramic glass, no expansion and very sturdy (many shops around the world sell cut to size hightemp glasses). Ofc the issue would be the bed sensor probably? Dunno. 

    first of all, there is no rule that says you need to own an S5 to make comments about it, but as you don't own one, other then trying to throw fuel fuel on a fire and trying to cause loads of negative feedback, what's the point of posting all kinds of nastiness on twitter and here that is also incorrect? 

    SandervG is a decent person and replies in a nice why, I for one am not nice. 

     

    some corrections to your post and your twitter-complaints

    your post on twitter:

    Quote

    "did promise a Aluminum Plate with the expensive UM S5 and now they will get a ‘free extra glass’ without any money back or price going down. Sorry but that shows a lot of what kind of company is. Specially now that they set themselves as PRO market"

    and

    Quote

    "The worst part is IMHO that they drop this on the forum, not a public release note, and their solution is very poor and cheap. They did promise an expensive high quality plate and now users get a silly glass"

     

    corrections: 

    -yes a buildplate was promised. they tried really hard, it didn't work out. shit happens.  Ultimaker offers a glass plate instead of an alu plate and if you need an additional solution Sander is actively reaching out as demonstrated above. 

    -what does this show? that they don't want to release a broken product like many competitors? yes it shows exactly what kind of company this is. a company that only wants to release something if it's good, not if they don't stand behind it. that is exactly what you need if you want to address a pro market. but nice job of trying to spin this super negatively. 

    -this forum is pretty public. at least, I just clicked community and then announcements. i did not have to go through a paywall.. if you would have owned an S5, you would have gotten an e-mail. I got one. If you would have been a reseller, you would have been informed. they updated the site. they updated the marketing material. If Audi doesn';t offer a specific option anymore, they don't take out billboards in every city to tell you that color X is no longer offered? did you expect a singing courier with a song-o-gram to tell you the alu plate is not coming? you don't know what you are talking about but yet you blame Ultimaker for not informing the mighty Neotko. 

    -yes they promised an Alu Buildplate. Yes they now get a glass plate. it doesn't make me laugh when I use it, so I don't know why it would be silly.

    back to your forum post

    -they made a promise and couldn't keep it. they are open about it. many companies tell you to take a running jump and offer you nothing. I think UM is handling it nicely. open for discussion, not deleting unhappy responsed, and trying to work out a solution. you are correct, that is not like E3D or Prusa, where they simply turn off promised features, don't deliver on them and then ignore the problem. 

    -why would you even suggest that people should take up legal action? you have no stake in this at all, yet you start making suggestions that people can certainly take up legal action for this. let me tell you, any judge worth their salt will laugh you out of the courtroom. because Ultimaker promised something, tried to the best of their abilities, and when they could not keep their promise, they offered fair compensation. perhaps not monetary wise, but they offered another buildplate in exchange for the one not delivered. how the fuck are you going to sue for that? 

    -your example of the UM2 has 2 sides. first of all, it's a great example of where they wanted to do something, but in the end couldn't get it to work. the UM3 shows why they couldn't get it to work. so yes, you are right. they overpromised and couldn't deliver on it. from the legal action perspective, once again, a swing and a miss. Ultimaker tried to meet their promise, was open about it, if they would get sued they have all the evidence they need to show how they tried and how they did not succeed, they choose to not release a solution that would suck, and have supported many initiatives from people trying on their own, also helping people that wanted compensation for this. that is why they did not get sued, not because it was not aimed at the pro market. 

     

    enough negativity for today. 

    I'm also unhappy about not getting an alu buildplate, but i'd rather take the glass plate and keep using a wonderful printer, then spewing negativity about something that solves nothing.

    your treating your customers very very poorly and have taken advantage of their trust. 

    i started out being on Ultimakers side expecting you to realize your offer was never going to be acceptable.

    what i want more than anything is acknowledgement that this entire thing has been bungled, and i want to know your doing to prevent it from happening to others in the future. this is the second time this exact issue has happened after all.

     

    be genuine, be honest, be fair.

     

    right now it seems like getting out of this without it costing ultimaker anything is more important than our trust as customers. 

    you should not have hyped up how great this build plate would be and then tried to convince us it wasnt really going to make a difference. dont you see how that is super shady?

     

    i will keep an eye on this thread for the next couple weeks while i think about how i want to pursue corrective action related to this. I spent about 8,000 euro on this printer and the stuff to get it going. this wasn't trivial but your offer trivializes it.

    i hope you find a way to do better or at least be more accountable over the next few weeks.

     

    its sad to see Ultimaker not standing behind its claims and promises yet again. the printers are so good, and the trust is so quickly ruined. 

     

    happy holidays all i hope your less let down about how this has been handled than I am.

     

    dude. let it go.

     

    you are treating this like Ultimaker's intention from the get go was to take your money, then take off like a nice cartoon-villain. 

    grow up. 

    you bought a printer. the printer was supposed to have an alu buildplate. Ultimaker tried really hard to get that to work. They could not get it to work. They tried. They really did. 

    so the outcome is not one they liked. nor is it one their customers like. I have 8 Ultimaker S5s. I chip glass plates when printing with engineering materials, and was really hoping for that build plate. do you see me attacking the company? 

    I for one have chosen to put my trust in the company that they will continue to deliver great products. and with every few steps forward, there will be a step back. it's called reality. 

     

    please explain to me how reaching out to all customers that have registered for the build plate via email, and doing a very public mea culpa on this forum, then offering something in return for the missed out buildplate, is treating your customers very very (note the double very) poorly? how is that taken advantage of customers trust? 

     

    stop overreacting, count to 10 and think about what has happened. you are fully in your right to be disappointed. if this is a deal breaker for you, i'm sure something can be worked out. and reading back, it seems you now want to send everything backa nd get your money back. looks like Sander even wants to help you with that.. I know many many companies who would have just told you to go take a running jump and even after all the attacks on the company you posted they still want to help you. 

    your post makes me sad.

    Nicolinux, Kman and I rodriguez, Thank you - all for the detailed answers to all of my questions. Really appreciate your great information to help me in my decision.  September 4th- will contact some resellers. Thank You !

     

    i know you have already received plenty of answers.. but i do want to comment on some things you said ?

    first of all; I've been lucky to switch to the Ultimaker S5 at launch, and have been running 8 Ultimaker s5s since the start, so I suppose that's about 3 or 4 months by now.. I run them 24/7 and I run them hard. my success rate has been close to 100 percent.. failures I've had have always been relatable to the weak part of the equation, namely me.. 

     

    I print mostly PLA, the rest is NGEN, Nylon, PLA+PVA, some exotic materials based on client requests, and the only failures I've had have always been me being hasty, knowing something would fail and then thinking "meh, maybe it'll succeed..". 

     

    as far as the 3D Hubs rating, I am one of the few hubs running the S5 on 3d hubs:

    if you look at this article you can filter on the S5 and get test prints done on them:

    https://www.3dhubs.com/blog/ultimaker-s5-on-3d-hubs/

     

    you are saying you see bad reviews? i don't see them for the S5 on 3D Hubs. on general, the print quality from the S5 either gets 5 stars from my customers, or 1 star if they don't get FDM.. i don't really get middle ground reviews to be honest. 

    My switch has been from the Um3 to the S5 and I can tell you with confidence that that has been one of the best decisions ever made. 

    I use the printers for small scale production run (right now printing 3200 pieces for a UK company) but also for small orders like drone parts in Carbon Fiber. 

    for me, these printers have been true workhorses and the most reliable printers I've ever used.. 

    I've been in the printing game for about 4-5 years now, always running small to medium print farms, and I've never had a better printer then the S5. 

    if you have questions, feel free to ask.. I'm not getting paid here to advertise these printers and if other printers were better, i'd happily tell you so.. go check out my hub at www.korneel.nl then you can see what I've done on just 3d hubs and how happy people have been.. hope that gives you some confidence..

    well. My german might not be best, but I think your translation is a bit more harsh then what they said.. 

    how I read it is that if you enable developer mode, you're free to do that. you should however realize that developer mode is the wild west, they will not provide you with in depth documentation and if you change stuff that damages the printer (let's say you crank up the amperage so now your drivers break or you change the parameters of the printer so the stepper motor rams the print head into the sides until it breaks) they can refuse warranty on that. I see no harm in that statement.. 

     

    furthermore.. if you download the full system image (search the forum here) and you do damage something like that, flash the system image back and no one is any wiser that you ever enabled dev mode.. so i don't see the point of the statement to be honest.. 

    i think it's more of a "we have to tell you this or our lawyers get angry" kind of statement then any real "yeah, you will loose all warranty as soon as you enable dev mode". 

     

    just be prepared that if you enable dev mode, do weird things that make the software crash, and you have to take the printer in to reinstall the software if you were enable to do it yourself, they might charge you for it.. and i see no problem for that.

    then again, I don't work for Ultimaker ?

    Both properly displaying the MAC addresses of both interfaces and the requests for static IP's are on our backlog. Not displaying the MAC addresses has indeed been an oversight that we are looking to fix quickly, but I'm not sure it can be worked in before our next release, so no promises.

     

    With most users so far we have been able to find a workaround for the static IP's, so this has not been a top priority for us before. However, we are getting a lot of requests (not only on these forums) for supporting more network configurations and are actively looking to build support for those configurations. It is on our backlog, but I can not promise you guys a timeframe for now.

    thank you for this open and workable answer ?

    @korneel Not going to quote all the points, but...

    I don't make the decisions on what is going to be done - I only gave my opinion based on my experiences with big and small networks, for big and small companies at the time I was involved in this - that included commercial and non-commercial sectors including University networks etc. So don't make assumptions on sizes I have worked with, please, even tho it is already 15-20 years ago

     

    At the time of implementation of the UM3, the use for static IP was moot (at least for those making the decisions). The stack, connman, should be very well able to handle it (being used on Android devices too afaik) but interface wise (hmi) nothing is defined. 

     

    Also, the impression of how it currently works is wrong.  The MAC address is always there (for both the cable as wifi connection) but we lack in the display to show this information (when the network is not active). I think that is an oversight from our part, as we just should show both MAC addresses.

    Unless I misunderstood your statement I quoted...

     

    well, based on your reply i am making assumptions. the universities in NL that I worked with over the past 10 years, all required static IP addresses and the MAC address to be registered against the ACL. amongst those are the 5 large ones in NL. we tried deploying IP Phones that could not do static IP addresses and that meant a whole design change request to go through the board. if we could have just had static ip's in those phones that would not have been needed..  

    i was referring to your earlier statement about how no-one would ever need static ip addreses and how DHCP servers would fix everything and then you make a statement about how the only reason for it would be for IT companies to make money. no-where did it use the sentence "in my opinion" and it is very clearly said by someone who is part of team Ultimaker. that's perception. 

    no-one in the networking field would ever make that statement in my opinion that manually assigning IP addresses is not needed.. but hey ho what do I know.. 

     

    my apologies for being unclear, I fully understand that both the WIFi and the Network adapter have their own MAC address, what i mean twas that for me as a user, i don't get that address, or as you describe it, get to see the address, unless a cable is connected AND a connection is made. that is mega weird. 

    sounds like a bug that can be fixed.

     

    let's not get into this DHCP fixes everything discussion, is plainly not true and i don't feel like typing 3 pages to proof it's not true.

    I disagreed with the statement that having a static IP is crucial. It is not.

    As @nallath mentioned: people WANT it - but with current technology there is no need for it.

    Speaking from experience having being part of network engineering and having to fix all kinds of weird static ip issues, mostly due to bad bookkeeping leading to double or even triple use of the same ip address - which are a hassle to find and fix.

    and that's where you're wrong kiddo. 

    the people that get to decide what is crucial and not are the people that give you money. those are your target audience. if enough come back stating they need this, it just became crucial irregardless of your opinion. 

     

    and if we're throwing in the engineering credentials; CCNA all the way to qualifying for the CCIE exam, you're looking at a properly educated networking engineer. 

     

    please listen to the people who give you money. they don't care about your opinion what is needed or not. they care about buying a product that meets their expectations.

     

    edit:

    still puzzled with the there is no need statement.

    using your new knowledge i described above, why is it not needed? there are simply customers that are not allowed to have DHCP scopes for certain segments by their security department..

    This statement already contradicts itself.

    Simply said: you want to install a DHCP service for every device out there, except it should not give out IP addresses being used by servers and printers... Hence multiple places to manage IP addresses. You have to record every static IP address; to make sure a) it cannot be given out by the DHCP server (using pools of addresses) and  b) it will not be manually assigned again and c) if a server is replaced, it will get the same ip number again...

     

    But sure, I guess IT companies love making money doing things much harder than they really need to.

    nonsense. really, this is not your field of expertise. this reply actually annoyed me.

    let me break it down as simple as i can because your reply really does not show any understanding for the average company.
    so any decent company is splitting up their networks into networking segments. you've got your DMZ, you've got your wireless, your guest access, usually layered server access and things like that. using firewalls, communication between those segments is controlled and it will help you protect yourself  against things like broadcast storms, unauthorized client access etc. 

    this is then usually managed by using separate DHCP scopes (not services) from a centralized and authorized DHCP service with usually 1 or 2 backups. 

    anyway, some segments have from a security point of view a MAC filter so no unauthorized devices will enter, and some companies (like universities) simply run B class public IP ranges where they need tight control over the usage of IP addresses. they can't just run a dhcp scope.

    so there are millions of super valid reasons for companies to require static IP addresses and use ACL's based on MAC addresses to control access to the network. 

    yes, they actually do record every IP address (which are usually in ranges where there is no DHCP scope configured so that point is moot).  and yes when a service is replaced it usually get's the same IP address.

    no, IT companies don't do this to make money, your view is based on sub 100 computers. your view works great for a home network, and does not work on the enterprise market. happy to have a discussion about this, but this is essentially my daytime job. 

    the way it currently works (you only get a mac address if you have a valid DHCP scope configured for this segment) is a mega weird strategy. i can live with the non-static IP addresses, but this makes me weary of the networking stack on this device if basic functionality does not exist. 

    please @Marco_TvM take these comments seriously. you are dismissing them in a way that shows you have done zero investigation in this area.

    Thanks for the stupid remark :+1:

    but on the Ultimaker main site, and the list of official reseller there is NOT 1 in the NETHERLANDS !

     

    And I know there are lots of shops selling Ultimakers, but it would be a little bit stupid that a Dutch company in Holland not having a official retailer in the Netherlands !

    wait what?

    what website are you on?

    also, I was serious on Holland. it ticks me off, it's not a country, The Netherlands is.

    so i go to the ultimaker site, I click order now, and it shows me those 4 in The Netherlands.

    once i click on the full resellers page https://ultimaker.com/en/resellers

    apparently the Dutch resellers are listed under global..

    YouMagine covered in spam

    Hi everyone! 
    First of all, thanks to everyone who feels a level of responsibility to alert the YouMagine team when spam emerges on the platform. I know as a community manager that such commitment and help from its userbase is really helpful and appreciated. During Easter someone felt it necessary to upload files to print your own firearms, and this is not something the YouMagine team supports to share, so thanks again for putting this on the radar. 

     

    But even though Ultimaker hosts this 'Youmagine-spam' thread, Youmagine and Ultimaker are - and should be considered as - 2 different entities. Feel free to share your reports here, after all we are an open forum, but don't expect Ultimaker to act upon it. 

    If you want to be sure your report falls in the right hands; send an email with your findings to hello@youmagine.com and they will take it from there. 

     

    More updates about where YouMagine is headed will be shared on their blog in the near future. Thanks! 

    just quoting this :)

    @SandervG is there any update on this? frankly , Youmagine is quite slow, doesnt always download correctly, and the spam is just growing.. while i understand that from an organizational structure Youmagine is different then Ultimaker, for us, dumb users, it's the same. could you lift a small portion of the cloak to hint in which direction it's going?

    1) Less noise (Desktop printer is close to your desk...)

    2) Stable print whatever material (yes we use ABS)

    3) Stable print whatever climatic situation (wind coming from window or from ventilation) also UVs

    4) No dust inside the printer (and attaching to oily rods)

    5) Overall less external variations between prints

    6) Better mechanical structure : more rigidity

    7) Futureproof: I think the goal is to put a 3D printer in every office (maybe every home one day), So a fully enclosed printer is the way to go....

    not sure I agree

    1)that would ease the symptoms, not solve the problem. it would be a lot more efficient if they made the printer itself quieter, not just isolated it. don't need a top for that.

    2)front-doors should be enough. down side of a top would be that you are now blowing hot air on the parts. you need to compensate for that, makes it evne more complex.

    3)agreed but front door should be enough

    4)should not make that much of a difference. most of the dust i find in my printers is from the actual extruded material and belts

    5) could be

    6)looking at the flexibility needed to allow for the shaft, i don't think it would matter much

    7)notsure if i get that. what would be the advantage?

    Printing with PP?

    in Materials & profiles

    Posted

    I've had great success with PP by using the glassplate, then spraying it with printafix , waiting a bit, then spraying again. just a 3 or 4 layers of printafix, then printing with the default cura settings. 

    no more adhesion problems for me :)

    I actually have a special glassplate for PP that is completely coated in printafix and i just never clean it.. works like a charm.
