V1.4

Minor Versionm

by Jonny Yeu

Introduction

ImportantThe following steps are only for CANVAS Hub units and not DIY Hubs.

In the rare case that your CANVAS Hub cannot be seen while broadcasting its built-in WiFi hotspot, please follow the instructions below. The following steps will reset the code found on your CANVAS Hub and reinstall as if it has just been unboxed by writing a new image file to the CANVAS Hub SD card.

Please note: ensure that you have already tried resetting your CANVAS Hub while moving it closer to your network router. Please also ensure that you have followed the troubleshooting steps here. The following steps should only be undertaken as a final option.

  1. I am trying to factory reset my hub S but the Hub S link above makes me ask for permission to access the google drive . I cannot get the image file so I can flash the unit. Thanks

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

  2. Disconnect the power cable from your CANVAS Hub and open it up by inserting a flat head screwdriver under the lip of the lid and prying the top lid off. Gently lift the PCB out of the enclosure. Flip over the board and remove the SD Card.

    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!

  3. Insert the microSD card into your computer. An adapter may be necessary.

    • Open balenaEtcher, and click 'Flash from file'. Load the image zip file.

    • Once loaded, Etcher should automatically select the drive for your SD card.

    • Select 'Flash!'. The process should take a few minutes to write onto your SD card.

    • Reassemble your CANVAS Hub and follow the guide for setting up your CANVAS Hub. Please note that your new web address is 'ABCD-CH-canvas-hub.local/'.

    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.

    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.

@bullot Sorry for the trouble, are you receiving an error when trying to flash? If so, what does it say? We have tried the image file on our end and are able to flash successfully.

My CANVAS HUB S doesn’t seem to be powering up when plugged into the outlet, but the printer light starts flashing once I plug the printer into it.

Could You please advice and assist?

I recently bought my 4th Hub-S off of matterhackers, since you dont sell them anymore, and it came with octoprint but no CANVAS plugin… the Palette 2 plugin was there, and netconnectd was working fine, but no CANVAS plugin.

So I downloaded and installed balena etcher, downloaded the appropriate disk image, disassembled the hub, reclaimed the memory card, etched the memory card, first etch failed. Reformatted card, reran balena, etch succeeded.

reassembled the hub, powered the server, accessed the server, designated the network connection, restarted the hub, while disconnecting from the hubs spot, and reaccessed the server via the normal means.

set the username & password, and stopping by the Plugins tab, I note that the CANVAS plugin IS present at this stage.

So I moved to update the software, software updated successfully and now the CANVAS plugin is gone again.

Is there a way to stop the update process so it ends the version where the last CANVAS plugin is present? Which version would that be?

Aeolus Scarpitta - Reply

i also attempted to get the canvas plugin via the plugins manager. (+get more, then input the canvas plugin’s github address, which is no longer in my clipboard), it runs thru the installation, then tells me to restart the server, but when I do… no CANVAS plugin.

what can I do?

Aeolus Scarpitta -

Apologies for the inconvenience as we’re experiencing issues with V3.0.3 of the Canvas plugin. Please revert back to V2.3.3 at this time and we will have a new release shortly: https://gitlab.com/mosaic-mfg/canvas-plu...

Gotcha. Thanks Jonny

What happens when a 2nd hub needs to be reset. To my knowledge, only 1 hub on a network can be named ABCD-CH.

Is there a way to rename these units once (or as they are being) updated?

Aeolus Scarpitta -

In the rare instance where you’ll need to reset multiple Hubs, you can SSH into the Hub and change the hostname, similar to these steps: https://pimylifeup.com/raspberry-pi-host...

I have so much to say to you, the Mosaic brand… But to keep it within boundaries… in my experience, having to reset a hub is 2 out of 9 times, so “rare” feels weak to me… I’ve got 4 hub S’s on my 2 Palette 2S’s and 2 P2Spros, and 4 other plain hubs on my single color machines, with 1 spare plain hub that went into rotation early, because… NOT rare.

You dont make ‘em anymore… you’re slow to update the plugins… should I regret spending thousands to buy into the MOSAIC ecosystem?

I would truely like to engage you, or someone, in non-hostile dialogue about how you intend to support every customer who bought one of your pre-Palette 3 machines, while no longer producing or supporting the equipment they bought.

Aeolus Scarpitta - Reply

*while no longer producing or supporting the platform they bought.

Aeolus Scarpitta -

Hi Aeolus, thanks for sharing your experience, we’re sorry that you do feel this way. Based on the numerous interactions that we have with customers who have a Hub or Hub S, it is rare that a reset needs to be done, especially multiple times. We do still have Hub and Hub S units available, and we just recently released plugin updates (V3.0.1 for P2 and V3.0.3 for Canvas). We have seen that with recent OctoPrint updates it has caused some issues with the plugins, which is why we’re moving to a more stable system via Canvas to control your printer and Palette 3 instead of continuing to navigate around OctoPrint’s restrictions.

Concerning our support team, please feel free to send us a message at support@mosaicmfg.com and we’d be happy to help. We intend to continue to support Palette 2 users, and still provide support to V1/P+ users on a regular basis. We fully intend to continue supporting all of our customers, regardless of which generation of product that they own.
