Introduction
Important: The 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.

-
If you are using CANVAS Hub S, the image zip file is found here.
-
Please download and extract the zip folder.
-
Update 11.29.2021: The image files above have been updated for Python 3. When launching Octoprint for the first time, a new Octoprint user account will have to be created. Upon launching Octoprint for the first time you may also see a server error, please wait for about 5-7 minutes to allow it to start.

-
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.
I have to wonder, if this is an SD card that might need to be accessed by the end user, why not make an external slot for it.
-
-
-
Insert the microSD card into your computer. An adapter may be necessary.
-
-
Verify which drive your microSD is present on (in this example, our SD card is on the E: drive).
-
-
-
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/'.
My flash fails on my hub s. The only thing written is abcd-canvas-hub-s.img with an x above it and flash failed. I have tried different sd cards with the same results.
Never mind. I used win32diskimager and got my hub s factory reset.
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?
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?
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.
i dont see a select image option !
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.

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.
