    Hey Mike, sorry for this inconvenience - the image files have been reuploaded and you should be able to access them now.

    If you open up the Hub, there should be a microSD card in a slot on the back. If you do not see this card, please take a photo and send us an email to support@mosaicmfg.com so we can arrange an exchange. Thank you!

    Hey there, could you please send us a screenshot of what you see on balenaEtcher to support@mosaicmfg.com? There should be an option to select the image file.

    can this web address is 'ABCD-CH-canvas-hub.local be change

    Albert - Reply

    Yes, there are ways to SSH into the Hub to do this, but it can be a bit technical. Unless absolutely necessary, we would recommend keeping the ABCD serial number after resetting.

    I would like to SSH into my Canvas Hub S after completting these steps and I would like to change the serial number back to the original, please can you help me?

    Nathan Blake - Reply

    Hi Nathan, in order to do so, we would need to create an image file with a different serial number. Is there any reason why you’d like to revert back to the serial number? It would take a bit of work on our end, and our software team is currently focused on P3.

    Jonny Yeu -

    Mini-SD shows as TWO (2) drives after flashing. boot (D:) and SDHC Card (E:). Is this normal?

    Neal - Reply

    Yes, that would be fine, we’ve seen it occur in a few instances.

    Jonny Yeu -

    I flashed the sd, rebooted the Canvas. Now when I connect to the canvas Hub wifi, and go to http://abcd-ch-canvas-hub.local, I get a 503 Service Unavailable

    No server is available to handle this request.

    Could you please try and connect to 10.0.0.5/ while on the Hub wifi?

  5. Find a spot to setup your Canvas Hub. We recommend positioning your Hub closer to a router if your printer setup permits it and ensuring that the USB cable connected to your printer is long enough to reach the Hub without getting in the way of any of your printer axes during movement.

    • Connect your power supply to the outlet and Canvas Hub. Check that your indicator light turns on. Once connected, please wait approximately 3 minutes to initialize and set up an access point to connect.

    • We recommend waiting for the entire 3 minute duration as trying to access your Canvas Hub interface too early can cause it to reset and prolong the process of getting itself setup.

  6. Locate your Canvas Hub serial number. This can be found on the bottom of your Canvas Hub unit or on the lid of the packaging box. The serial number has the format of XXXX-XX and is not case sensitive. In this case, the serial number is '0ALX-CH'.

    • If the Canvas Hub has been factory reset, the new serial number will be abcd-ch

    • Once your unit has been plugged into the power for 3 minutes, you'll be able to connect your Canvas Hub to its internal website.

  7. At this point, your Canvas Hub is broadcasting its own network that can be located on your WiFi networks. The name for this network will be the same as your serial number with the format 'XXXX-XX-canvas-hub'. In our example, the network is called '0ALX-ch-canvas-hub' or 'abcd-ch-canvas-hub'.

    • Even if you are connected to the Canvas Hub's WiFi, it may indicate a status of 'No Internet'; this is normal.

    can i manually connect to the network, its not popping up as a network option to chose.

    hanaa habashi - Reply

    I’m not finding it on my wifi list either. I have done the factory reset and the new address should be abcd-ch-canvas-hub.local/ but it just ain’t there.

    Next step?

    Hi Clara, is your network 2.4 or 5 ghz?

    Jonny Yeu -

    Is it normal that the Wi-Fi on the hub is disconnected from the reboot screen?

    song - Reply

    Hi @althd0656, when you go to Network Connection and enter the password for your home/local WiFi network, it is normal that during the rebooting stage the hub will disconnect from its hotspot and then switch over to the network you entered the password for.

    Adalyn Ordono -

    However, it does no reconnect to the home network after a reboot. In the “Switching WiFi” message, stop and change to “Server is offline”.

    Is it difficult to connect if there is a lot of WiFi around me?

  10. Once Canvas Hub has connected to your home network, ensure that your computer has also reconnected to this network. For some users, your computer will reconnect automatically but for others, you may need to re-enter your credentials.

    • If you're having issues with connecting your Palette and printer to your Hub, please try:

    • Unplug your Palette from the Hub.

    • With your printer connected and powered on, attempt to connect to your printer via OctoPrint by manually selecting the serial port instead of the AUTO selection.

    • There should only be ~2 options to select from, so if one does not work, please attempt the other options until you successfully connect.

    • Once connected, plug your Palette back into the Hub and connect on the OctoPrint interface.

    • If you're still running into issues, please visit our page here.

  14. just now saw that 5G networks are not supported. Is this also true for the Palette 3 pro and hub ?

    Dennis Mellon - Reply

    Hey Dennis, apologies for the error on our end. Palette and Hubs will connect to 5G networks, just not 5Ghz networks.

Why does my webcam not function with the Canvas Hub? I have an existing Pi that works just fine with the same camera. If this is actually a loss in functionality being caused by the Canvas Hub, I don’t understand why the company would sell product that is inferior and proprietary to just providing the plugins and instructions for OctoPi.

Jonathan Zimmers - Reply

Hey @zjonathan, we apologize for any confusion. The original Hub cannot handle a webcam as the Pi inside is not strong enough. It was built for users who preferred to purchase a Pi to connect their Palette and printer, with preinstalled OctoPrint and CANVAS Hub plugins. For users who already had a Pi and preferred to build their own Hub, we created a support article here: mm3d.co/canvashub-plugin

The CANVAS Hub S, however, is capable of handling a webcam, and we usually refer to this list of compatible webcams as a recommendation: https://github.com/foosel/OctoPrint/wiki...

Hope that helps!

Alina - Reply

Don’t get me wrong, the Palette is a great concept and solves a huge problem. That being said, I never saw one note on any product page that talked about webcam functionality. As a potential customer at the time, I would have no reason to look in support documentation. If I would have known, this information would have been enough to convince me to go with the Palette 2 S instead. I do large scale prints that take many days to print, and now I am stuck with either retrofitting my old Pi or coming up with another solution just for a video feed, neither of which I expected to have to do when I bought your product.

Jonathan Zimmers - Reply

Hey Jonathan, the CANVAS Hub S works with any model of Palette, so you would not have to upgrade to Palette 2S if you were interested in adding a Hub that could connect a webcam. That being said, I can pass this feedback onto the team so we can better communicate the capabilities of the original Hub in the future.

Hi. I Just recieved my Hub, and once logged into the Hub Octoprint local, I go to set the network connection, and there is NO “Network Connection” In the Octo-Settings (wrench) tab!!

Here’s a link to an image of the Settings Tab: https://cdn.discordapp.com/attachments/7...

Hey Aeolus, which version of OctoPrint are you currently using?

Jonny Yeu -

Thanks for the reply, Johnny, and for looking into this…

Heres a screenshot of the current versions tab of the Hub i recieved.

let me know if you need more…

Thanks for sharing. Could you please select the “Update All” button on that page to bring everything up to date? OctoPrint should be 1.7.x, and P2 and Canvas plugins are now in V3.

Jonny Yeu -

done. The interface instantly tells me that everything is up to date. Force Update in advanced settings does the same.

I’m certain this is because the hub has no internet connection. It says so in my Windows available networks.

How do i get it a internet connection without a “Network Connections” option?

Aeolus Scarpitta -

“correction-

the interface instantly tells me “Update Successful”. “Check for updates” Returns “Everything is up to date”

Documentation says to follow onscreen instructions to connect to a wifi network, but I saw no onscreen direction in any of Hub / octoprints setup processes

Hi @woodenship, can you try setting up ‘netconnectd’ following the steps here? From there, our modified plugin of netconnectd can be installed using this URL (Plugin Manager > Get More by URL): https://github.com/OctoPrint/OctoPrint-N...

Adalyn Ordono -

no. I dont speak github. I bought a device that was supposed to be set up already. So I’d like one of those, please.

Aeolus Scarpitta -

order number EN-10704

Hi @woodenship, alternatively you can reset the hub following the steps here and it should do a fresh install of Octoprint + Palette, Canvas and netconnected plugins: mm3d.co/canvashub-reset

Adalyn Ordono -

that, I can try. Thanks

I have 2 new out of the box Canvas Hub’s Purchased 18 months ago. Tried to configure Hub #1. WiFi does not function. Polled with 2 Windows machines and 1 Mac. The hub does not appear. Rebooted many times no change. Download Hub Image, burned to factory SD card, same result. Burned Image to a new SD card same result.

Tried Hub #2. Same results. WiFi not functioning.

Any Suggestions?

Hey Jeff, is your network 2.4 or 5 ghz?

Jonny Yeu -

So, followed the directions and updated the Palette plugin then ‘update all’ as told in the video, now I have a Canvas Hub that has no ‘Canvas’ tab. Been googling and everything talks about updating octo by doing X Y and Z which I have 0 experience in a linux environment so its like speaking another language to me. Looks like I now have an expensive snazzy looking brick.

Russell - Reply

Hi there, sorry about this issue you’re seeing. It would be best to do a new installation of Octoprint and our plugins following the steps in this Canvas Hub Reset guide. This will have you write a new image file onto the microSD card inside the hub, which includes a newer version of Octoprint and our plugins which are compatible with Python 3. Please be sure to download the image file for your correct Canvas Hub model. If you run into issues while doing this, please contact our team at support@mosaicmfg.com and we can provide further assistance.
