Has there been any update to the implementation of the "User Authentication" feature? Browsing through forums, this feature has been requested by users for years now. Is there an expected timeline? We would really like access control so we can network the printer at my company.
Here you @jkal Not sure what printer you have but there is quite a robust ecosystem for Ultimaker printers.

@ultiarjan Are you able to provide the files for your UM2+ direct drive conversion? I'm running a UM2+ extruder on a UMO+ and would like to try out your setup! Thanks.
@ansonl it is listed above at the bottom of this post. The link is S5_FlexDirect.zip

JAVA is not used for the development of our printer firmware, CURA slicer, nor for the cloud applications (Digital Factory, Marketplace, Contributor portal, Account services, eLearning), so in no way our products are impacted by the Log4J vulnerability

Hello I am very new to this community and just got my ultimaker s3 set up yesterday. I am running a 1.75mm PC filament print using the aa .4 nozzle with the bed set to 115c nozzle at 180c and a flow rate of 140%, I have great adhesion using a brim but after the brim and first 2 layers of the parts were printed I get a strange error message where it thinks the filament has run out, I can resume the print, and get maybe 1 min of run time with the printer, but then the same error message. The filament is in the feeder and has good tension on it, maybe too much (i can see the teeth marks in the filament running through the feed tubes) but I cannot figure out why this keeps happening. This has happened with both the included UM holder and the one included in the picture. Does anyone have any thoughts?
Use 2.85 or turn off the flow sensor. Why are you using 1.75?

This is great feedback! I asked around about dual feeders for the Ulta maker too, because my board does support it, however everyone told me that it was a bad idea due to the amount of headache that the company went through. This was apparently why they developed the um3. I asked around on the forums and that was the general consensus. Great feedback!
The Mark 2 is a great mod that will works! https://www.magnetic-tool-changer.com/

It’s more as a warning to those in this thread. I did exactly what others are doing in this thread, and apparently that messes up the main board. I’m just posting that historically accurate conversation we had over it. More as a warning to others.
as for the warranty, it would be good to know what actually went wrong, however support is limited. Having a relatively new main board go bad sucks. In addition it was to show that support staff is actively monitoring Facebook groups. So, just be aware and be careful what you post.
https://www.facebook.com/groups/1646291262322434/permalink/2698708323747384/
What did you mean on Facebook when you said "Any suggestions before I try to call Support only to be told that I voided some sort of warranty by resoldering their board? :-)"
You then said "There’s clearly nothing I could’ve done to ruin the motherboard" but you never shared the photo of the soldering in the Pi and other boards, why?
We are here to help but you have to be honest about your intentions.

You either have a stripped tube or worn collet. You can trim a few mm’s of the tube for now. This could also be a good time to replace it and pickup a new collet. It’s a yearly suggested replacement per the maintenance schedule. The tube, not the collet.

Folks, I am getting good results by putting 1.75 into UM3 "as is" (no changes to the machine). This is what I am doing:
1. Temperature 215. (this is becuase the feeder has weaker grip on the filament. Make it easy for the feeder)
2. Layer height no more than 0.1mm on 0.4 head. On 0.8 head I allow myself to go higher (up to 0.4). With 0.25 I would not do it at all. (this is because you really want slower feeding). Decreasing print speed also works.
3. Use better filament holder, with thin axis and a silicon lube spray will not hurt. I designed my own: https://www.thingiverse.com/thing:4354166 . This will help the spool roll, further reducing the required feeding force.4. In CURA, feeding rate set to 265% (which is, of course, diameter ratio squared).
5. Do yourself a favor and watch first 2-3 layers.
6. Same feeder, same PTFE tube, same print cores. No changes to the ultimaker. It just works.
With right settings I have no "feeder slips". However, they might be happening without me noticing, so maybe you should refrain from that from big high-quality prints. But honestly, I am getting perfect results even on fairly complex prints.
Are you saying you didn't adjust the feeder tension? -

I update the first time by wifi and has begin the problem, in second time I updat form usb but the situation it's the same.
I add 3 shorts videos, so you can see what'up:
-start print (slam limits and wrong middel position)
-calibration nozzle (try to rise up the nozzle 2 from the left side )
-abort print
That is not the normal place for probing. Rerun the 'Calibrate the Lift Switch' under Maintenance | Calibration
As a quick check, are the x and Y motor screws loose? They are on the outside of the machine. 4 screws per motor.-

Did you udpate with Wifi or USB? There are two firmware vs depending on the S5 design. You should use the one for the Ultibot design.
18 hours ago, 0maquina said:dear all I bought an S5 7 months ago, I have had various problems since the beginning and the technical service has not yet been able to solve them. the worst happens today, I'm working for valves for hospitals, for the Covid19 emergency in Spain, this morning I do a firmware update, and the machine has stopped working, it is no longer possible to calibrate, it seems to interpret the inverted axes , calibrates from left to right and is unable to raise and lower extruder 2, a disaster I would like to do a firmware downgrade, but my tencion service does not help me. I read in this post that it is possible, where I can download or receive the file. thank you very much I'm very hurry. -

Hi
I'm most certainly *not* going to dive into the disassembly without guidance. That indeed *could* raise all sorts of interesting warranty issues.
I'm not quite sure that "official channels" would be any better at blowing a piece of loose crud out of a sensor than I would. I'm also not sure that my doing it would have any different impact than their doing it. Yes, that *assumes* a specific answer to an as yet un-diagnosed system illness .....
Indeed if the cover (or whatever) comes off and there is a pile of broken bits where the feeder used to be, I haven't done anything of value opening up the device. Part of my guess here is that I have a simple / common / normal issue rather than a full system failure.
Bob
If you email support, they will walk you through how to do maintenance and repairs yourself. That is always faster. We just don't want you to accidently make things worse. Personally, I'd love a way to actually vacuum away debris vs low it everywhere inside. https://ultimakernasupport.zendesk.com/hc/en-us

I do the same, I wish I could turn that fan down to the very minimum with ABS
What brand of filament are you working with, by the way?

The first attempted print, I did let it go, and it failed with an error message that print head did not reach temp fast enough.
Found the pile of purged material on the floor of the printer, which is usually not a good sign.
This Purge behavior, if correct, should be better documented so folks know what to expect. I attached a picture of the mess left on the left side from a single hotend 1 purge of the material station load process. Seems like way more filament than I would expect for a purge, and movement of the head front to back during the process is also seemingly unnecessary. Hence why I thought the S5 had lost its mind.
I attempted another print and let it run. The first nozzle purge completed with the mess I show, then it switched nozzles and went to the right side (off) the build plate. It then Failed with ER54 trying to load PVA from Bay E to hotend 2.
I attached image of failure notice.
There does not seem to be any way to get past these error messages on screen, other than a power reset?
No button on screen to push to clear etc?
Pulled about 6" of PVA back out of material station in bay E that looked pretty mangled. It was not up to the Printer in the Bowden.
I also cleared filament from nozzle 1 back though the material station and Bay A too.
I Ran print one more time with expectation it will use material loaded in Bay B and F, which it did. Purge ran on left side in black, to load hotend1, and then for the first time, I saw it also make a big ole pile of PVA off of the right side of the build plate. Big mess on the floor of the printer, but it is finally running a print.
So I would say my problem is solved, but I strongly suggest the behaviors are documented in the quick start guide and the user manual, where I found no mention. Also there should be a way out of these error messages on screen.
Thank you
Good ideas and I can understand the confusion, I’ll report this to support, the apparently useless wiggle is actually used to make sure that filament breaks and falls instead of get pulled into a print. Personally I thought about constructing or printing a slender waste bin to insert on each side and collect those. Maybe even incorporate a silicone edge to wipe the nozzle. But for now I just collect and remove the purge. -

As long as the filament is loose from the printcore it is fine to gently pull it out trough the material station.
Define goes crazy?
The purge on the side behaviour is meant to form the filament into a nice tip so it can be pulled back past the printer feeder reliably.
While technically possible the recommended support training is to disconnect the Bowden tubes from the feeder bottom, cut the filament at the entry hole and pull from the back. We don’t want filament to break and fall back into the merger and into the wrong place, leading to a time-consuming tear down. Breaking filament is usually from old filament or some event that caused a ground down section that is weak and prone to breaking when pulled on. Just my suggestion.Starting purging may get more optimized in future firmware releases, we don’t want to change the end sequence since that nice clean tip (audible break) is also key to avoid contamination in the material station components.

@TheRealJoost Did you ever email the America's inbox? Let's shorten the chase here. I am an Application Engineer for Ultimaker that helps companies in Canada, the United States, Mexico and South America. If your request was made it would go to a reseller or me. Let me know what I can help, what material, and what you are after. I forgot what your company makes and what you;d be printing. As you are aware, many factors to consider on a print from surface quality for visual prototypes to large and robust applications for robot arm end effectors, custom vise jaws or even prototypes. It is really going to be up to your own preference for what you are willing to pay for or what time you are willing to spend adjusting base profiles for your own needs. We do pride ourselves on having many profiles to get you started, that is why the software is free. You are open to try it now with a myriad of printers out there. Many, many companies, use Cura or the Curaengine in their own products. DM me or just email me at l.rodriguez@ultimaker . I am located in Kansas City.

This issue has been resolved. Please contact support (or me) to get the patch. It will be included in the nest firmware for the S3. Thanks for reporting everyone!

Hey,
I was wondering if there are any known issues or any other users are experiencing this issue.
First observed with putty on LAN (no filters) and then verified with a direct crossover connection from a linux laptop running dnsmasq.
Port 22 is closed (connection refused.)
Dev mode is activated, verified on S3 Display, numerous restarts. Tried re-enabling etc. etc.
Now I don't want to say that I might not still be overlooking something silly but it seems exceedingly unlikely.
Anyone got something?
Thanks,
sono
How were you connecting to the machine? Wifi, ethernet?And you enabled DEV mode? I can get this addressed if I have this info, thanks again! -

Allwinner A20 is a common ARM SoC. The board mentioned in that post has USB and HDMI, so I don't know why they are using a TTL / RS232 adapter but either way getting a console on such devices is trivial unless the device has been intentionally locked down, as is not the case here. Once on the console, it should be quick to find the cause why ssh is not running or filtered. Should be a one time thing.
It has not been locked down. In fact SSH was never removed from the firmware. Could you share your logs with me so I can get them in front of the Devs at HQ? They do not have any problem enabling Dev mode and using SSH. We are trying to figure out why some users are having this problem.

Chip - know that with an olimex cable you should be able to connect to your S3 printers and access linux that way. This is a serial (on the printer end) to USB cable which can connect to linux/mac/pc that has "serial terminal" software that lets you use a console that talks to your S3. I don't have an S3 (just S5 and UM3) so I don't know 100% that this will work but I'm 90% sure it will. I sell these olimex cables in my store by the way for people in USA at thegr5store.com. If you are in Europe then it's easier to get them directly from the manufacturer.
It sounds like UM disabled ssh in the newer versions of their firmware. This is unfortunate.
No, this is incorrect, SSH was not removed. We are investigating why these users are not able to connect but engineers at HQ are.

This is not accurate. We will have an status update Monday.

This printer shipped in January of 2017 and I cannot find any support tickets for that serial number. If you change your mind, I'd be happy to assist you. I have no idea if you have ever asked your reseller or Support for help. Please let me know if either didn't.

Please contact your reseller and ask for 5.4.6 until the next update. While another firmware is coming, you can use it today. I have done so at a show. It will not be perfect but you will be able to use it.

Your printer will also display this after certain conditions.
But just go into the update menu and it will be there.
