    You have to realize that there are many thousands of UM printers out there but only a handful of complaints on the forum.  Something like 0.1% of people with UM printers complaining on the forum is not convincing enough.  However if all 10 or so distributors each hear from 10 resellers each hear from 10 UM owners, (1000 complaints) that will get the attention of UM and hopefully they will disable this upgrade until a few more things are worked out.  New people are upgrading their firmware every day.

    Not to be argumentative and yet; it is “highly” probable and very likely that the percentage of owners/end users and businesses active on this forum is a token percentage; who knows; maybe it’s 0.1% which would equal 100% based on your sampling.

     

    Furthermore; I personally speak with a couple USA distributors that without reservation share that they too have the same trouble getting element of urgency support as such attempt as able to satisfy the customer in house.

     

    Having shared this; I too feel that the Ultimaker Team is far less connected to the end user, particularly when there is an issue than they want all to believe.

    Certainly this would create a controlled zone however, it’s far from practical much less realistic for many businesses.

  3. Sarcastically with what I consider to be a level of truth embedded; don’t hold your breath as the concerns as conveyed by many versus the Ultimaker Team’s response don’t live in the same arena.

     

    The level of concerns shared that are not being addressed with any element of urgency as clearly evidenced by the actions, or better put; lack there of by the Ultimaker Team is truly dumbfounding.

  4. Well after all I have read this firmware situation is beyond fricken ridiculous.

     

    There is absolutely no reason for this and “if” it were an anomaly; which it is not, then an “easy” roll back should “always” be in place. 

     

    For many these printers are a component of, it not their sole livelihood. The cavalier attitude and less than timely resolutions makes clear that after the sale support is far less important when compared to the seemingly never ending trades shows that the Ultimaker Team market within.

     

    Come on Ultimaker; get your act together!!

     

    Speaking of firmware; long ago I was assured that I would no longer be pestered with the relentless pop-up telling me that there is a newer version of Cura; how about resolving this too as it has long  passed the point of annoying.

    Chiming in here because I'm hoping to find a solution as well. I am setting up a university library makerspace so we will have thousands of people with physical access to our UM3 printers. Since anyone that can press the wheel button can look up the IP and gain access via Cura Connect, we can't really enable network access. I was hoping only admin users would be able to control printing (send, abort, etc), not anyone with a computer/mobile device. Is the UM5 more secure?

    S5 = the same

    The title says it all. Since upgrade to 5.2.8, I have lost the camera stream (it's black). I reset the Cura Connect, to no avail. Any advice?

    I can’t speak to your issue however, I installed the latest firmware last night; the two step process with no apparent issues.

     

    Having shared this I have not initiated a print yet however, I just looked at the printer via the camera remotely via DDNS and it works fine and then accessed it via Cura 3.4.1 via the local network and it is visible.

  7. Well it’s with mixed feelings that I make this post.

     

    A 18 plus hour print just completed with no issues however, it was only able to be completed with the filament sensor turned off.

     

    IMO this makes perfectly clear that the calibration and or operational characteristics of the sensor to do work well with PVA. It remains my hope that the FW presently in beta has aggressively tackled this issue as it has plagued us since day one as well as many others.

     

    If not for the suggestion from “kmanstudios” to turn the sensor off I would still be hitting the resume button ..... over and over again throughout the printing process with there never being a valid issue with the PVA; phenomenal.

     

    As I said at the onset of this reply; mixed feelings because on one hand having the print completed without any intervention was wonderful and yet knowing that the sensor does not provide the solicited protection is troubling.

    I cautiously suggest that you could do more to dry the PVA. It may be already bad when it comes from the shop, and a dry box will not correct that. I suggest a simple test. Try to bend the PVA. It should have the Young modulus of a uncooked (raw) Barilla spaghetti: it should be rigid, and break without even bending. If it bends before breaking, or it does not even break, it's not sufficiently dry.

    For details: https://arxiv.org/pdf/1810.07069.pdf 🙂

    Thank you; no caution is necessary as I like using PVA; in fact without it many prints could not be considered and yet I am a bit frustrated so all assistance is appreciated.

     

    Based on what you shared; the PVA that I use; both new and after being dried on the build plate is never truly dry.

     

    I have read many comments about PVA only wishing that I truly understood its characteristics. Some say it’s brittle when wet, others just the opposite.

     

    When I have had the PVA brittle to the point that a slight bend will cause it to snap then I have experienced it breaking in the Bowden tube when loading and I am unable to straighten it to insert it into the feeder.

     

    So using your comments as shared and my shared experiences how do you successful load and use PVA if it will break with only slight bending?

    Hi Kman

     

    Being a service provider, PVA is a PITA to manage (application, removal) so I use sprays mostly.

     

    Printing ABS with PVA doesn't make the trick, generally I go with Dimafix, but for that specific grade 3D Lac is sufficient.

     

    I use glass plates from my local supplier on a Mankati Full-scale XT Plus, 4mm heat tempered glass made to measures, without chipping issues so far.

     

    What's why I'm wondering if there isn't an issue with the genuine Ultimaker S5 glass plate....

     

    BTW it would have been good to have the aluminium build plate.

     

    I mean not to throw a random punch; and yet.

     

    Your issue is a great example of what the aluminum build plate was solicited to eliminate.

    I had the same problems at the beginning. I then started to dry the PVA tremendously. I always keep it in a heated dry box, it hardly has a molecule of H2O left inside. Lo and behold, all the issues are gone! You really need to seriously dry your PVA, it will work miracles. Since you say that the problems are always with the PVA, it seems clear that the issue is not the mechanics of the printer, but rather the filament. Dry your PVA, I tell you, you will be surprised. But you need to dry it actively and continuously with heat and forced ventilation, anything else will not be enough.

    Thank you for sharing your experience.

     

    I will step up that which I have been doing.

     

    To date I keep the filament in an air tight dry box.

     

    After a print I place the PVA in the original cardboard box and set it in the Ultimaker S5 on the build plate at 50c for a couple hours before bagging it with desiccant within the dry box.

     

    The printer operates in a controlled 65-70 degree F environment with relative humidity between 30-40% so as I understand; this is well below the PVA issue threshold.

     

    Giving up the sensor long term is not an option.

     

    I have read comments from others with the same issue and I understand that sensor calibration tweaks were made in the latest beta version; once it is released as stable I will try it and hopefully in concert with my actions good results will follow.

    Ever just tried to turn off the filament sensor?

     

    Setting (Gear symbol)------->Settings------->Scroll down to the flow sensor.....actually, it is secong on the setting area. But, I am not on the S5 Beta.

     

    Also, PVA can just be a pain about setting this off because as soon as humidity makes it, by the least amount, pliable, it will give false errors.

    Thank you and no.

     

    The filament sensor has saved me on several long prints during which the filament gets bound on the roll; without it the time loss would have been a disaster. 

     

    The filament sensor along with (dare I say) the aluminum build plate were the 2 significant reasons why the Ultimaker S5 was purchased.

     

    The current print is 18 plus hours and I have had to restart it no less than 4 times in the past 6 hours so I will test your theory.

     

    I just aborted the print, cleaned the build plate, disabled the filament sensor, and will now see how it does.

     

    BTW; I am not using the beta version.

     

    Your input is appreciated and I will refrain from sharing my thoughts until the print has completed.

     

    Thank you again.

  12. Any update to this issue?

     

    It has remained a pervasive issue with us, removing the filament and cutting a section off and reinserting it, aborting and restarting the print, reloaded the latest FW, cycled the machine, tried a new roll of filament, dried the filament per Ultimaker’s directions, etc. and the issue remains.

     

    It has become an impossible situation.

     

    BTW; always with PVA (maybe with the transparent too) so I lean towards a sensor calibration issue.

     

    Thank you

    Version 5.1.8 from 2 January, 2019 available. Tried to update to this release but still on 5.1 Oct. 2018 after finishing.

    What am I doing wrong.

    Regards, Harald

    Relax 

     

    I update over the air and every time it begins the process and then seems to hang. I have to reboot the S5 and initiate the update a second time and then it works.

     

    I hope that you experience the same results.

     

    Please update this thread.

    Shadowman, 

    I've seen a couple of your posts on the forum. You seem like a wealth of information and quite the crusader against the whole Aluminum Build Plate debacle. So let me make sure to say thanks!

    Ok so now I have a followup question. 

    Are you using a glue stick with PLA as well. It seems that small prints in the center of the bed are fine, but today I did a big print using the whole with of the S5 build plate and I noticed one corner peeled up a bit (shrinkage/warping). 

    I didn't put anything down on the glass because most of my PLA prints stick to the heated bed just fine. Are people also using glue stick or hair spray prep for PLA and Tough PLA prints or just other materials like Nylon, CPE and ABS?

     

    Thanks 

    DR

    First of all; thank you for the kind words as I know it is a bit of a double edged sword when I make some of my posts; the bottom line; I care.

     

    Now to your question; I too have printed much PLA without anything but a clean glass however, like you I too have been caught off guard when the occasional print lifts. As the result of this I prepare the glass “every time” thus insuring I have no adhesion related issues.

     

    It only requires a modest amount of time and glue stick and then spread it as I shared earlier to afford me “peace of mind” knowing hours later that I will be happy rather than frustrated.

     

    I wish for you only the best.

     

    Thank you again.

    Hi guys, 

    New to the forum. 

    So I have an UMS5 and I'm working on a prototype that needs to be printed in Nylon (I think). 

    I'm looking for something heat (100 deg f) and salt water resistant that will get a bunch of direct sunlight, I figured Nylon might be a good solution. 

    I read that Nylon should be printed on a glue layer to keep from the nylon sticking to the glass an possibly causing chips in the glass? 
    I've found glue sticks messy to apply and hard to apply evenly. 

    I've previously used Aquanet/Hairspray on an older printer, but before I go spraying my beautiful glass bed with hairspray I thought I'd ask the forum if anyone's been using Hairspray instead of Glue with Nylon prints on their S5? 

     

    Any comments/feedback would be appreciated. Thanks for participating in the forum and helping the community as well as UM users like myself. 

     

    DR

    I can’t speak for others however, I use glue stick when needed and apply it to the glass and then I use a moist paper towel to evenly spread it around; no issues.

    I can't seem to find any other reports of this odd behaviour, but on my S5 when I want to change filaments, hitting unload doesn't cause the hot end to heat up, it just goes straight to yanking the filament out of the print core, cold. This often causes a necking and snapping of the filament end, leaving a slug of old filament in the core, which then takes quite a while to flush through.

     

    This can't be right, can it?

     

    I also find that now and then the UI can get stuck waiting to detect something, like a new print core installation, which doesn't trigger. I've ended up having to power cycle the machine and try again to get it to spot the new core. Firmware is 5.1.8.20181207

    Definitely not right; my S5 does not act as you’ve described.

     

    I don’t have the solution but rather the confirmation that you need one.

    I think it's only gonna make a difference if you print right on the glass. With glue or spray, it won't make any difference.

    Hi Smithy

     

    Your thoughts do not negate mine nor those of many others.

     

    I have had random adhesion issues and after understanding that the glass build plate has completely different properties on each side I am certain that I “now” understand why.

    Really? So there are 2 different sides on the original glass? This is extremely important information!

    Never knew this.  Some glasses, (i have about 5 on the UM3 and 2 on the UM5) are turned over because of chips. And the i remove the little sticker to be able to use it flat. After that i swapped the directions probably several times. Introducing a extr variable.

    Sander, we should have known this much sooner!

    I am with you RudydG

     

    As much as I appreciate the information; this should have be part of the original information as provided with the printer as well as with the replacement glass build plates.

     

    I have always been told by both the  Ultimaker Support team and the distributors that both sides of the glass build plate are the same hence the ability to turn them over when chipped.

     

    In my opinion; this is another great example of value of the aluminum build plate.

    It's just a bug that seems to have come back, once you can reset your machine it will be fine and with luck the next update will fix it for good and its also due to add support for LED's going totally off and not just dim. So i would wait it out before cutting into wires on a £6k machine.

    It was great to read your reply; thank you.

    None of the vendors/distributors I get listed at Buying options mentions that there will not be an aluminum build plate.

    The only difference between these resellers is if they advertise that the aluminum build plate will be shipped free of charge to existing S5 owners or if it will be an add-on accessory.

    That's only the official resellers ultimaker.com. If you look at the numerous other vendors, it's exactly the same. They all keep advertising the aluminum build plate.

    Hi asb

     

    I shared the same with SandervG a couple days ago after he asked you for specific distributors still soliciting the aluminum build plate.

     

    An associate of mine made a couple calls to different distributors and was told of the benefits of the unique aluminum build plate as associated with the Ultimaker S5.

     

    Thank you asb for sharing your findings.

    For me it is easy to explain, I bought the S5, not because of the aluminum plate, I bought it because of the build volume and the possibility to print abrasive materials. Honestly, I got noticed about the aluminum plate first, after unboxing 🙂 - that's maybe the reason why I don't see it that "hard" or unacceptable as others. 

     

    I can also understand that some are disappointed about the end of the aluminum plate, especially if this was the only reason why they decided to buy the printer. But I still believe it was better to say stop now, than waiting for a product that cannot be mass produced as expected and which probably makes more problems than the glass plate. 

     

    We all know that it was in the marketing channels that this will be a unique feature of the S5 and even because of that, I have full respect for the decision Ultimaker made. They truly believed that they can accomplish the production and now as they cannot, they are honest enough with the coming out and try to find individual solutions for customers which are not happy with a second glass plate. So, in my opinion, we should be fair and give them the time and the chance to compensate for this issue. 

     

     

    Maybe I don't understand what you mean, but this combination is working great and also with different brands of materials. UM materials and print heads are detected by Cura and you can print without modifying any setting. When you try to use Simplfy3D for example with your S5, then you see what you really have with Cura and how perfectly Cura works with the Ultimaker printers.

     

    Last but not least I have a wish for 2019, that we all will act objective and fair. Everyone should get a chance to make things better next time, also Ultimaker, and with all disappointment, we should not forget, that they have built and build hopefully also in the future great workhorses for our businesses and hobby activities.

    Smithy 

     

    I do understand why some things such as the aluminum build plate are not of great concern to you but respectfully I ask that you not dimish the value it has to others; including myself.

     

    To clarify; my comment about Cura; my attempt was to make clear that it is Ultimaker’s software; supported, maintained, and bundled with their printers however, as an open source software anyone else can use it. Add to this, those with Ultimaker printers can twist and tweak it “at their own risk” as well as assist if desired with future development of it. 

     

    Open source and free when associated with a Ultimaker printer does not mean no responsibility.

     

    Many folks, including Ultimaker, continue to imply that because it is open source add free that no one should complain; this is both wrong and frankly; laughable.

     

    Like you; I successfully use the Ultimaker created material profiles and in my case with both  Ultimaker’s hardware and private labeled NFC filament and by and large have had nice consistent prints. 

     

    To be very clear; I like the Ultimaker S5 printer however, I don’t like that I have not received that which I paid for.

     

    A fairly simple concept.

  22. 2 hours ago, Smithy said:

     

    In my opinion and experience, it is exactly that. For me, the S5 and also the UM3 are plug and play printers. Unboxed, connected, installed Cura and started the first print. Everything fine, no problems. Try a China printer or a Prusa, and you will see the difference. If someone needs more plug and play or is overwhelmed with the usage of an Ultimaker printer, then you have to buy something in a much higher price category or consider to use a 3D printing service if you only occasionally need 3D prints.

     

    I like my UM printers and have no problems with it. Also not with the Cura software, which runs quite well on my Apple machines. They produce nice quality prints and the community here is superb regarding support and help, which no commercial support can offer in my opinion. 

     

    All known issues are not really issues for me if the led is dimmed or off is not important for me. If there will come an aluminum plate or not, is not important for me - I can print every material on glass with or without the help of other adhesion tools. If Cura is not working on my machine, it is not the fault of the printer.

     

    Everyone who still thinks he cannot print without an aluminum plate should contact Ultimaker. @SandervG offered more than once to contact him directly to discuss a possible solution. So instead of complaining here again and again (which gets boring with the time), should do that.

    Smithy

     

    Your input and shared experiences are always appreciated.

     

    Smithy, the issue is not what the Ultimaker S5 can do as I agree with you that it printed out of the box and frankly; as I have shared before; nicely albeit slow. Add to this the PVA support has opened many very cool printing opportunities.

     

    The issue for me is the continuation of Ultimaker and folks such as you down playing the importance of what was told versus what is reality.

     

    Yes; anyone can print without an aluminum build plate however, because one can does not mean that not receiving it should be discounted.

     

    Regardless of you personal opinion and the use of your printers Ultimaker has not taken responsibility for what they did.

     

    They sold a product stating that it was a fully developed product with unique  “value” related features that after nearly 6 months of selling them Ultimaker simply said; sorry it’s not going to work.

     

    How you can accept this as acceptable is very surprising to me.

     

    Now with regards to Cura; the Ultimaker S5 was sold with Cura as an integrated piece of software; the heart of the printer designed to be “best” used with Ultimaker’s private labeled NFC filament. I bought into this along with a significant inventory of Ultimaker’s NFC filament and back up hardware.

     

    Lastly; I am all to familiar with other printers having been lead down the path of “someday .... maybe” which is why I spent so much time discussing my experience and “real” concerns with Ultimaker and the distributors prior to the purchase. In addition; I read the reviews presented by the various publications; speaking of which these reviews all presented the Yin and Yang of the Ultimaker S5 printer.

     

    Cost = high 

    Unique features such as the highly solicited aluminum build plate = offset for the high cost.

     

    These reviews significantly assisted Ultimaker with the S5 rollout; how would numerous reviewers cad publications rate it today?

     

    Yes.....

     

    SandervG and I have communicated and we will carry our conversation further after the holidays and yet; I feel that Ultimaker needs to be more transparent in how this situation is being handled because IMO; one on one conversations with SandervG cloak the issue and there is truly no common ground but rather a series of independent placating gestures.

     

    Take care

    The PPA is maintained by an Ultimaker employee, and it is far superior to the appimage - at least if it works.

    Recently a 4.0 version was released. Now Cura does not even start anymore.

    Regarding what Ultimaker considers to be "supported": Officially, Cura seems not to be supported at all. If one asks a question, the support request if forwarded to the local distrubutor. And the local distributor considers Cura unsupported because "it is open source" and it "is not part of the Ultimaker printer package". It is some kind of an add-on goody. If I can not get answers to questions, I think this qualifies as "unsupported" as well.

    And yes, the Appimage doesn't work properly, either. Last version I checked could not connect to the S5. Besides that, it is terribly slow, not integrated into the operating system, it is not safe, and it does not get updated through the OS mechanisms. The appimage is a very, very bad crutch.

    Looking further into what Ultimaker considers to be "supported", next brick wall you will hit is the firmware and shell access. As far as distributors - which are responsible for the support - are concerned, shell access does not even exist. From the Ultimaker end, shell access is undocumented and also not officially supported.

    And it does not stop with de-facto unsupported software and firmware. Considering the aluminum build plate which we were led to believe to be a unique feature of the S5, it seems to be now "unsupported" as well as we won't get the aluminum build plate. When the S5 was introduced, it was considered a unique selling point and advertising focused on this feature which only the S5 offered. The first disillusionment happened when my S5 arrived without the aluminum build plate, three months after the product was put onthe retail shelfs. Altogether more than half a year after the product introduction, Ultimaker decides that the product introduction marketing was… well what - a mistake? … and that there will not be any aluminum build plate and neither a technicallly equivalent replacement nor another appropriate compensation. Offering a 2nd glass plate is nothing but an isult, especially considering the major benefits of the aluminum print bed.

    If the S5 wasn't so expensive, all of this would be a bad joke. But as it is, it's a massive offence.

    Good day asb

     

    I had to read your post a couple times because I find that much of what you shared mirrors my thoughts and why I remain so troubled.

     

    Beginning with your last product related issue; the aluminum build plate; as much as I try, the chain of events associated with the aluminum build plate concerns me on a very significant level. Add to this, I too considered Ultimaker’s glass build plate offering an insult.

     

    Now to Cura; the fact that it is “open source” is only moderately interesting as this plays well for Ultimaker as they have a significant number of unpaid users constantly able to contribute to their product development. This however, does not negate Ultimaker’s responsibility to maintain a stable program. 

     

    The Ultimaker S5 was marketed and sold as a fully developed package that includes  “Cura” and it being integrated into the Ultimaker S5 and designed to work seemleasly with Ultimaker’s private labeled NFC filament. We were told that this package was created with the primary end user being “businesses”. It was marketed and sold as a plug and play printer designed to be used by the average person with no inherent 3D printing experience. This was not marketed nor sold as a hobbiest printer.

     

    The price point of the Ultimaker S5 is high however, because it included (as they solicited) several years of development prior to its deployment along with many uniquely developed features to be specific to the Ultimaker S5 as such I was able to justify it at that time. 

     

    At this moment I question much of what I was told.

     

    Having shared this; yes the Ultimaker S5 is able to produce nice prints. It’s slower than most printers and the resulting prints are not of a quality unique to the Ultimaker S5 but rather consistent with many printers sold at a much lower price point; including other Ultimaker printers.

     

    Prior to purchasing the Ultimaker S5 I asked many many questions of Ultimaker directly and their distributors “because” I have been mislead by other 3D printer manufacturers before as such I was very skeptical.

     

    Ultimately I trusted Ultimaker
