Does your DHCP server advertise another NTP server to use? If no NTP servers are available either from the local network or the internet, the printer will indeed not have a valid time. We've fixed the reliance of a correct time with the current stable, but of course, this will only help you when updating from 5.2.11 to a next version.

Hi Sassw, what steps did you do to install the firmware (from what version did you update, USB or over internet?) In what state does the S5 fail when you now boot your printer?

Can you outline the exact steps that you took? For most users, doing the factory reset enables them to do the Wi-Fi setup again and have a connection setup. You need to perform this setup before the toggle becomes available. Can you verify that you did the Wi-Fi setup before you toggled between Wi-Fi and ethernet?

Just to confirm; you are on the 5.2.8 version? Did you do the factory reset and try to connect to the Wi-Fi again? For most users, doing a factory reset enables them to go through the Wi-Fi setup. You need to do the setup before you can enable the Wi-fi toggle. If you are unable to connect the printer to either Wi-Fi or Ethernet, please contact your sales partner for a solution.

A quick workaround for this procedure is to manually feed in the filament at the start of the print. This will be fixed in our next release.

Yes, because the "Never" option after having done the calibration once does not guarantee the best results. We've changed the way never works; it now does not apply any offset. You now have the option to manually calibrate the build plate and have no offsets applied when you choose never. But I would still like to see the results of the diagnostic tests to see how we can fix your problem.

Can you check and do the procedure as explained on our support pages? Especially the new diagnostics on 5.2: https://ultimaker.com/en/resources/52808-capacitive-sensor-low-performance-or-interference-detected With this update, we've made the auto leveling more reliable. Unfortunately, this also means that we have to be more strict about what readings we 'approve' so that the auto leveling procedure does not start a print with less-than-ideal values. For example, a lot of customers had problems because of blobs being under the nozzle when the probing procedure would run. We now heat up the nozzles so we squash the blob and have much better reliability with this procedure. Can you report back with the readings of the diagnostic test? (Oh, by the way, do you have the auto level frequency to anything other than 'Never'?)

Hi All, We've got reports from users trying to update their unconnected printers using USB that they could not initiate the update. This is due to a failing consistency check, prohibiting the update when the printer can not get the correct date over a network connection. To prevent confusion, we've removed the download links from the update page. We will reinstate the links soon.

I've tried this myself by building a positive mold, then creating a food save negative from silicone. However, the surface was too rough for the chocolate to become nice and shiny. I did not yet try to smooth out the printed part, it's on my big list of things to try 🙂

@ScanHD Can you please DM me the logs of your printer? I would like to see what is happening in your case and see where we can help. You can also email them to w.elfring@ultimaker.com Settings -> Maintenance -> Diagnostics -> Save log files to USB

@ultiarjan , thanks for trying this version! We also probe the 'movement area' of the first layer since we need to move there with the nozzle, so we also need to compensate for build plate deformation in order to prevent potentially scratching the bed. That is why you are seeing the bigger probe area you illustrate.

Ah, I missed that in your original post. Are you able to DM me the firmware version and logs after it happens? We'd like to investigate this further since this kind of behaviour normally only happens when there is an error. But looking at your video, it seems to finish the print just fine.

We've made some changes to the end-print-behaviour in the next firmware update that will reduce the sound by a bit. However, it is indeed nothing to worry about. The build plate dropping down for the last few mm's does not damage the machine.

The URL from Smithy is the same one that the printer accesses when it's downloaded through the network, so it should work. Additionally, could you try to download these files through another browser?

Hi Dextop, What printer are you using and at what firmware are you on currently?

Welcome to the forums! The IP and MAC address are indeed found in the menu. There is a small hoop to jump through when you don't have a connection yet and want to see the MAC address. I've outlined how to get that here. There is indeed no driver necessary. If your IT department needs ports: 80 (API, Webcam, Cura, Cura Connect), 5353 (Zero-conf/mDNS). Hope this helps you out. If you've got more questions, please let us know.

We've fixed this issue in the next release of the firmware, it removes the delay in moving the printhead away from the model.

If you drop the print head bracket down, you'll see a small board at the back of the bracket. That is the sensor. May I ask, is this a UM3(e), an S5 and how old is the printer? If it is an older UM3, it might have a print core spring that has become too loose. Either way, please contact your reseller.

Hi Florian, Can you try to power down the printer and try again? This might seem stupid, but the sensor is highly sensitive and calibrates itself. If by any chance, you've touched the sensor or had your hands in the machine at the time it calibrates, you could get strange readings causing the printer to not find the bed. If the problem persists, it could be that the sensor is broken. In that case, please contact your reseller.

I'm checking our official stance on this topic and will get back to you.

@Bigbrit, what is the issue that you are experiencing? I noticed that you mentioned that your WiFi disconnects every so often. Is it completely unreachable by Cura and Cura Connect? Does the printer menu show it is disconnected?

That does not look good. Can you check a few things to rule out some causes? Can you check if you're in the latest version of the firmware? We improved the end of filament detection a lot since the first launch. Also, has this always been the case with your S5, or did this behavior start recently?

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.

Hi @asb , the ethernet mac address should have been in the 'Network' dialog, however, currently it is not. I've added this to our backlog to be fixed. There is a workaround: The last part of the hostname is the same as the MAC address and does keep on-screen even if a network cable has not been plugged in. For WiFi, this is a bit different because we actually power down the module (security/power reasons) so we can't get the MAC address before you switch it on. Hope this helps you in the meantime.

Hi @GBuchwitz, an external HDD would work just fine, assuming no extra drivers are needed for the disk. Any USB Mass Storage device will work. Keep in mind, you can also use the UM3/UM3 Extended to test with as the control hardware is mostly the same (except for the screen ofc). Can you post the HDD type so we are able to check the compatibility? For ethernet; You can use any network cable For most modern devices, it does not have to be a cross cable. The device should auto-sense the pairs. My Mac automatically creates a DHCP server that gives the Ultimaker the IP address it needs. For Windows, this might be locked down by your IT department. The last option might be just asking your IT department how you should use the machine, they might be able to set up a dedicated network, or come up with an option that let you do your work (as they should ? ).
