Hi, Thanks for your reply. In that case I'm not sure what's going on. Does the printer have an active network (Ethernet or WiFi) connection? Maybe an embedded engineer has more info on this, I'll forward them this thread. Chris

Hi, You can turn developer mode on and off via the printer's display (in the settings menu). Depending on whether you have an Ultimaker 3, S3 or S5 it'll be in a different location in the menu structure. Chris

Hi @3dprntz, I've read through the log files and can't really find anything obviously wrong in them. There's not error messages related to the cloud connection. Furthermore in our cloud back-end logging I can see that the printer successfully connects. Could you try the following steps for me to see if it shows up on digitalfactory.ultimaker.com? 1) Remove the printer from your account (on https://digitalfactory.ultimaker.com/app/printers, on the printer tile menu select "remove from account") 2) Perform a factory reset on the printer (via the settings menu on the display). 3) Go through the connection flow again now that all software should be in a clean state. 4) If it still doesn't show up, please send me the logs again. Regarding the display, it's best to contact first-line support at your Ultimaker reseller. It might be a firmware or hardware problem, and they are equipped with handling these scenarios. Chris

Hi, So what you're saying is that you see this screen, but the printer is not visible on digitalfactory.ultimaker.com? Which firmware version do you have installed on your Ultimaker 3? Could you send me the printer logs (exportable from the display to USB)? Chris

@inworks I'm not sure about the future roadmap for UM3, but I'm sure we'll release an update for it somewhere in 2021 that will include the later additions to the communication protocol between printer and cloud (unlocking features like webcam screenshots).

Hi, For remote monitoring I advice to use the cloud-based Digital Factory connection instead of a VPN solution. You can get your printers connected by navigating to https://digitalfactory.ultimaker.com. Chris

The "Check for account updates" button synchronizes Marketplace plugins and materials that were either added to Cura while signed-in, or those added via marketplace.ultimaker.com. However, you can achieve the desired effect of synchronizing all Cura settings (including custom profiles) by using the "Cura Backups" plugin, available in the "extensions" menu. Simply create a backup on one machine, and then restore it on another. This will copy over all the settings.

Please export the printer logs via the touch screen settings menu and upload them here or send them to me via DM. Without those we can't really see what is going on. Chris

You'll be happy to hear then that an upcoming firmware release will allow you to enable a firewall, blocking all incoming traffic from the local network. This is full, 100%, network security, whereas passwords are definitely not. By enabling this firewall, users are forced to print either via USB (physical security can prevent access to this if needed), or by using the Digital Factory, which has full user management and access management in place (especially if you're a company on an Ultimaker Essentials subscription). So we take security very seriously and are doing continuous improvements in this area, as expected by more and more demanding customers as this industry matures. We just don't want to implement features that give a false sense of security.

This build indeed still contains that bug (it was made a little while ago). Hopefully there'll be another build soon with some of these bug fixes that were already released on the S3 and S5, as well as additional features for the Digital Factory.

This feature was indeed requested a short while ago, in this thread: I've brought it to the attention of the product owner of the Digital Factory. By the way, was there a specific reason to have the lights turned off in the first place? Chris

Hi, Can you tell me what the printer was actually doing at this moment? Was the object still on the build plate, waiting to be removed? The Digital Factory merely displays what the printer firmware is telling the status is, so in order to debug this we'd have to find out what was happening on the printer. Could you maybe upload the printer logs, or send them to me in a private message? Chris

@smithy's suggestion will work. Alternatively, plugins and materials will also be automatically un-linked from your Ultimaker account if you remove them from the 'installed' section of the Cura Marketplace while signed in.

Firstly, it is not trivial, because we are dealing with a security model that touches the physical and digital domains. For example adding a password to prevent stopping a print job via the local web UI does not add much value, because anyone could walk up to the printer and do it via the display as well. As a result, you'd also have to deal with authentication on the printer itself, which is much harder due to limited input possibilities (no one really wants to enter a full password on such a small screen). The embedded team is working on some options, but there not just not there yet. Secondly, it is actually not very secure, because in the local networking you cannot deploy HTTPS (this standard requires domain names, it does not work with IP addresses). So any password entered will be sent in plain-text over the local network from your browser to the printer. Very easy to intercept. You also have to store this password then on the printer. Doing SSH into the printer firmware when it's in developer/debug mode then allows you to find these passwords on the file system. Even if that's encrypted, you'd still have plenty of points to start reverse engineering them. Thirdly, adding authentication to the local web UI is not in line with our future direction. We're implementing all new functionality in the cloud-based Digital Factory, which has proper authentication, two-factor authentication, and way more options to expand upon. The local web UI is mainly there for legacy reasons. For those customers who require that UI to be not accessible, the firewall option works fine. Hopefully this gives you some insight into our line of thinking, and why we very likely will not add password protection to the local web UI.

"print over cloud" is only available when: 1) you have actively connected your printer to the cloud (via https://digitalfactory.ultimaker.com). 2) the printer cannot be found by Cura on the local network (which is always the preferred networking route). So this is a pretty active opt-in. The reason we're doing more and more via the cloud however is to actually prevent issues with local networking, which are very common due to the many different LAN setups our users have. If you're worried about security or privacy, I can refer you to our support section about this topic. As for the camera, this is not available in Cura when using cloud, but it is available on https://digitalfactory.ultimaker.com when using an Ultimaker S3 or S5 with the latest firmware, or when you use the local network on any of our connected printers.

Hi, The regular Ultimaker 3 firmware (5.2.12) does indeed not support these features. I'm not sure you how had these features before, but that was likely via the local network UI instead of the cloud? Chris

Hi, We don't disclose specific dates for any product or feature launches, hopefully you understand. Kind regards, Chris

Hi, There currently is no such feature indeed, as @Dim3nsioneer mentioned. I'll forward it to the product owner of Digital Factory to see if there's something that can be placed on the roadmap. Chris

Hi, Could you upload the logs of the printer itself here or via a private message? You can extract them to a USB drive via the settings menu on the screen. It seems the printer is successfully connected (hence the 200), but the data the printer's sending is malformed and not accepted by the cloud. Chris (p.s. that 404 you posted first is expected, that URL only gives a 200 if you're an Essentials customer)

Hi, Can you please upload some logs from the printer (you can dump them to USB from the settings menu) so we can have a look what's going on? Chris

Hi, Great idea! Currently you can only send new print jobs from Cura and add those to the queue of the connected printers. We're also working on something that will likely solve your problem! Chris

Hi, Please export the printer's logs via the settings menu on the touch screen and upload them here or send them to me in a private message. Hopefully the logs will reveal why the printer is no longer appearing in your Digital Factory. Chris

Hi, You can send an account recovery request to the Ultimaker support team via https://support.ultimaker.com/hc/en-us/requests/new. Chris

Easiest would be to dump the whole ZIP file to a USB drive from the printer's touch screen settings menu. Then upload the ZIP here or send it to me in a private message.

Hi, The firmware teams are working on improving network stability. In the mean time, can you upload your printer's log here so I can attach them to our internal tracking ticket? Chris
