v1.4

Minor Versionm

Introduction

If you are building your own CANVAS Hub, you'll be able to connect your printer and Palette via OctoPrint to control, load, and start your print files. The following steps will walk you through how to install the necessary plugins if you already have a Raspberry Pi with OctoPrint and would like to create your own CANVAS Hub.

This setup guide is intended for users with an existing OctoPrint server setup and connected to your printer. If you do not have OctoPrint setup we would advise that you visit https://octoprint.org/ to setup your own OctoPrint server and then continue with this guide or purchase CANVAS Hub and follow the guide Setup Guide: CANVAS Hub. If you choose to use our free OctoPrint CANVAS plugin you will have the same abilities as CANVAS Hub users to control, load and start prints with your Palette 2 (Pro) (S) and printer.

  1. Open the OctoPrint interface and update to the latest version of OctoPrint.
    • Open the OctoPrint interface and update to the latest version of OctoPrint.

  2. Once updated, select the Settings icon. Once in the Settings window, select Plugin Manager. Scroll to the bottom of the page and select Get More.... You'll enter the Install new Plugins... screen. From here, you'll be able to install a plugin from URL.
    • Once updated, select the Settings icon.

    • Once in the Settings window, select Plugin Manager. Scroll to the bottom of the page and select Get More....

    • You'll enter the Install new Plugins... screen. From here, you'll be able to install a plugin from URL.

    u cant just click and paste from here it automatically dwn to pc as a zip file

    and url destination

    this is from this page https://gitlab.com/mosaic-mfg/palette-2-... try paste that )

    this is the bit that is stalling me

    • Copy and paste the following file destinations URLs in the following order. Note: These plugins will need to be installed individually to be successful.

    • Palette 2 plugin file destination URL: https://gitlab.com/mosaic-mfg/palette-2-...

    • Canvas plugin file destination URL: https://gitlab.com/mosaic-mfg/canvas-plu...

    • Do not directly download and unzip the files. The plugins will only work when installed from URL in OctoPrint.

    • Please also note that if you have any existing GCode scripts on your OctoPrint, this may affect certain CANVAS Plugin and P2 Plugin functionalities, such as filament loading. Please consider reviewing/removing conflicting scripts if certain functionalities are not acting as they should.

    When I try to install the two plugins from URL, I get an error:

    I only have this problem with octopi 1.4.1, isntalled fine on a machine running 1.4.0, maybe the issue is with the latest build of octoprint?

    Andrew Beresford - Reply

    Hey Andrew, this does seem to be related to the latest Octoprint release. We’re looking into this issue and will provide a fix shortly.

    Jonny Yeu - Reply

    i cannot see the full zip files to copy?

    James Peverley - Reply

    You wouldn’t need to download the files, simply enter the URL into OctoPrint and it will download the plugins.

    Jonny Yeu -

    I have tried to install the CANVAS plugin several times to my octoprint server. The log keeps telling me that install is complete but the tab is not showing up, nor do I see it in my list of plugins. The Palette 2 plugin seems to work fine.

    Steven B Seggelink - Reply

    Hey Steven, thanks for your patience with this. We are currently looking into this issue, and we will update this thread as soon as possible.

    Alina -

    Hey Steven, so sorry for the delay and thanks for your patience with this. The Canvas team will be releasing a new plugin version on Wednesday the 19th to address this. The new version should resolve this issue. Please find the links to the new versions at mm3d.co/canvas-setups and let us know if you continue to have trouble.

    Alina -

    Steven, I have the same problem as listed. I tried the recommendations to fix but still no joy. What should I do to correct this issue? Scott

    M Scott Murphy -

    Still not working….

    James Peverley -

    please help… have the same issue.

    DeeFlu -

    @deeflu Please follow these steps: - Uninstall Canvas and Palette plugins from Octoprint.

    - SSH into the RPi, if you are using Windows you can use PuTTY. You can also use an IP scanner to get the IP address from the RPi, using the IP address as the hostname to connect to. Once you have the IP address, copy and paste it into PuTTY as the host to connect to.

    - Unless you have already configured your RPi login, the default id and password to access the Raspberry Pi is:piraspberry (if you haven’t reset your Hub, the password is your serial number in lowercase in this format: xxxx-ch

    - Once the connection is established, please enter the following three commands separately.

    a. sudo apt-get update

    b. curl -L https://get.octoprint.org/py3/upgrade.py --output upgrade.py

    c. python3 upgrade.py

    - Once the Python update is complete, please reboot the RPi.Afterwards, reconnect to Octoprint and re-install both the Palette and Canvas plugins.

    Jonny Yeu -

    Quick question, did palette 3 pro gonna have it ?

    michael laurin - Reply

    Hey Michael, there will be no Palette 3 (Pro) plugin for OctoPrint, so you will not be able to use OctoPrint with P3, but you will have access to our own custom printer control software. You will be able to control the printer and the print from Palette’s screen or from a webpage.

    Alina -

    Canvas 3.0.2 is unfortunately still not visible in Octoprint 1.6.1. Palette 2 is visible and alive.

    Raimund Unnewehr - Reply

    I’ve got the same issue as Raimund and Steven. The plugins are visible in safemode of my octopi, but in normal mode only the Palette 2 plugin is visible. Canvas doesn’t even have an entry in the config.yaml yet, still shows as finished install in the interface. Can someone please help me out?

    I’ve also uninstalled all other 3rd party plugins…

    Amacello - Reply

    I was now able to install Canvas v2.3.3.

    https://gitlab.com/mosaic-mfg/canvas-plu...

    Does that info help?

    Amacello -

    i can install 2.3.3 as well but that does not work with the current web instance of canvas.

    I initially thought maybe this had to do with the python update from 2.7 to 3.x so I reinstalled octopi to the new version of octopi 0.18 that supports 3.x, but that did not fix it. Still no response to my email to mosaic support and no response here. While I can manually down load the files from canvas and upload them to the hub and make it work it is highly inconvenient.

    Mark Burton -

    Canvas still doesnt work with Octoprint 1.6.1, this has turned the palette 2 into a massive very expensive paperweight. Please sort this ASAP.

    James Peverley - Reply

    I’ve also tried backtracking to Octoprint 1.4.x, still didn’t work for me. What did work was using Canvas 2.3.3. But this obviously is not what we expected…

    Amacello -

    We’re very sorry to hear that you’re experiencing this issue. We've seen a handful of these issues, and just wanted to confirm which version of OctoPrint that you're using, and if you've noticed if any other plugins were affected.

    Also, could you please search for new software updates and also check the Canvas plugin disable status as those could be potential blockers.

    Jonny Yeu - Reply

    Hello Jonny Yeu,

    As i already stated I've tried the three versions 1.4.1, 1.5.1 and 1.6.1 of Octoprint, each with all three versions of 3.x and version 2.3.x of the Canvas plugin. Only combination working so far is Octoprint 1.6.1 and canvas 2.3.3.

    The raspberry pi 3b+ running octoprint also received a fresh firmware update.

    I uninstalled ALL other plugins except for the ones that came with Octoprint, still couldn't get it to work.

    Now, with 2.3.3 canvas, and the latest palette plugin, I was able to additionally install thermal runaway and others, and it still works.

    Thanks for your help!

    Amacello -

    Thanks for this information, Amacello. Our software team is currently working on a fix for this and an updated plugin should be released in the very near future. We appreciate your patience with this!

    Cureent version constantly gives me this error

    Canvas

    Connection Status: Not Connected to Canvas

    There seems to be an issue connecting to Canvas.

    The plugin will automatically try to re-connect until the connection is re-established.

    In the meanwhile, please download your Canvas files manually and upload them to the Hub.

    Thanks for sharing, it seems to be an issue on OctoPrint’s end. However, we have heard that reverting back to V2.3.3 does work currently: https://gitlab.com/mosaic-mfg/canvas-plu...

    Jonny Yeu -

    it does and it doesn’t. the plug in runs but I cannot add the device in canvas so i cannot send to the canvas hub from canvis

    Mark Burton - Reply

    Hey Mark, the plugin shouldn’t affect the ability to add a device to your Setup in Canvas. Just to confirm, you’ve followed the steps in this support article (mm3d.co/canvas-setups)?

    Jonny Yeu -

    Yes I have followed those steps. in the old plug in 2.3.3 it says my account is connected.

    when I go to canvas it says connect your device and asks for the code.

    If I install the 3.0.3 I get

    Connection Status: Not Connected to Canvas

    There seems to be an issue connecting to Canvas.

    The plugin will automatically try to re-connect until the connection is re-established.

    In the meanwhile, please download your Canvas files manually and upload them to the Hub.

    so no neither the old plug in nor the new plugin will connect to canvas. for downloading the files from canvas

    Thanks for sharing. I’ve responded to your e-mail thread and have just asked for OctoPrint log files if possible (mm3d.co/octoprint-logs)

    Jonny Yeu -

    We are experiencing the sames issues as described above. We use Octoprint 1.6.1 and after updating the Canvas plugin to 3.0.3 the Canvas tab is not showing up. Nor do we see the Canvas plugin within the Plugin Manager. If needed i’m willing to downgrade the plugin to 2.3.3 but i’m unable to find this online? Can somebody help me?

    Mike Bloemink - Reply

    Additionally to my previous post I'm also unable to manually print by downloading the file from Canvas and uploading it to Canvas Hub. Palette 2 is 'connected', but when I then press connect to my Snapmaker 2.0, the connections with Pallete 2 gets disconnected and I get an error that he is unable to connect.

    I'm than again able to connect again to Pallete 2 'connected' but as soon as I than connect tot Snapmaker 2.0 the same happens all over again.

    Hey Mike, currently it seems to be an issue with the OctoPrint update. To get around this while still using V3.0.3, please follow these steps:

    - Uninstall Canvas and Palette plugins from Octoprint.

    - SSH into the RPi, if you are using Windows you can use PuTTY. You can also use an IP scanner to get the IP address from the RPi, using the IP address as the hostname to connect to. Once you have the IP address, copy and paste it into PuTTY as the host to connect to.

    Hi Jonny Yeu, thank you for your reply I’ve tried to login on the RPI but unfortunately I get ‘access denied‘. I’m sure we didn’t change default inlog credentials but it doesn’t work. I’ve tried all deafult inlog credentials i could find online but none of them work.

    Any ideas how to factory reset without login?

    Mike Bloemink - Reply

    Hey Mike, sorry for the delay. Could you please try using your serial number as the password, with the format xxxx-ch and all in lower case? Please also feel free to email me directly (jonny@mosaicmfg.com) and I can respond to your inquiries much quicker.

    Jonny Yeu -

    Hi Jonny, i’ve tried emailing you (4 days ago) but while i don’t get an reply i assume i perhaps have a wrong emailadres? Nonetheless, I've tried the password based on the serial number what you suggested but still no luck. What other options do I have?

    Mike Bloemink - Reply

    Sorry to hear that! Have you reset your Hub in the past? If so, could you please use the password ‘raspberry’? I’ll check our spam folder for any missed messages, but you can also reach us at support@mosaicmfg.com.

    Same issues. Cannot load Canvas Plugin successfully. It seems to install ok, I reset and the tab is not there. I’m running Py 2.7, upgraded to Octoprint 1.7.2. I appreciate Jonny Yeu steps but I have no idea what he is talking about.

    Please send me a detailed step by step guide to get my Palette 2s up and running.

    We have an improved plugin/image file that will work with Python 3, and we expect to release it soon as we’re still testing to ensure that it works properly and allows the Canvas tab to appear.

Hey Marco, sorry for the trouble. What is the error you are seeing? Please make sure you are selecting “copy link address” versus “copy”, as this will not copy the full URL.

Hi Palette2 Plugin is not working for me it shows installed but does not show up in Plugins or on the Tabs. If I reinstall via the plugins it shows it as uninstalling and installing but still will not show up in the plugins list or as a Tab. Is there a compatibility problem with the latest Octoprint release. Thanks

b. curl -L https://get.octoprint.org/py3/upgrade.py --output upgrade.py

c. python3 upgrade.py

- Once the Python update is complete, please reboot the RPi.Afterwards, reconnect to Octoprint and re-install both the Palette and Canvas plugins.
