    Does this work with the Palette 2?

    Hi Rmilyard, yes, the Change Filament feature is also available for Palette 2: http://mm3d.co/p2-fw-notes

    can you update this for the P2?

    When I hit 'change filament' during a print it goes to the page to change the filament and pauses the print, but none of the drives are able to be selected (they are the light blue color and do not respond when pressed).

    What am I doing wrong?

    Is there any way to automate filament change or add a line in gcode (M600?) in order to ensure the filament change is done at the right time?
    Should we change the filament as soon as the last splice for a color is already done?

    Thanks for clarifying...

    Yes, you could manually edit the GCode with commands to allow you to change filament, but M0 may be the better option as M600 may cause the printer to unload filament. You would be correct to set this command after the last splice.

    Thanks for your reply Jonny. Yup, M0 makes more sense! Tried it and it worked fine. Nice model too...

    I'm now trying to use the Advanced functions in the Palette plug for Octoprint. Speed does not seem to change until the first splice. Is this normal behaviour? Shouldn't a M220 S150 be sent at the beginning of the print or at least after the first level as well?

    You're welcome! If you're using the Slowdown during Splice option, this will only slow down your printer's print speed when it senses that a splice is occurring. Otherwise, it will use the print speed that is set in your slicer settings.

    Sorry but that's not correct. The "Normal Feed Rate" can be set to values different than 100%, up to 150% max. This is a great option, but I wish it could go up to 200%. I tend to play a lot with speed during prints based on the current layer complexity... When the "Normal Feed Rate" is not 100%, Octoprint should start the print at the requested rate, really!

    I reached out to our CANVAS Hub Lead and he shared this information:

    1. Speed only changes when the first splice happens. This was by design as we felt this feature was focused for splicing, but I can see why you would want to have the normal feed rate applied right away as soon as the print starts (i.e after loading offset is done). We will make that change for a future plugin release.
    2. Concerning the 150% feed rate, we chose this upper cap because we felt it was reasonably safe for most users and that going above that would be at the user's own risk. We’ll consider increasing the maximum cap to potentially 200% for a future plugin release.

    Thanks for considering this Jonnny. I use to rely on scripts with shell commands or text editing the Gcodes to change the speed while printing remotely. Things like slowing right down for the last layers can improve print quality, while increasing speed for simple geometry layers will decrease print time tremendously.
    I'm finding out using a Palette can increase user options far beyond multicolor printing. Ping feature is great in that regard...

    Wow, Mosaic keeps on amazing me. Suggested features on 21/1.these are implemented just 6 days later on 27/1. These features will be great for me. I find 150% feed rate at normal speed does not impede functions. I do need to slow splice feed rate to 80% or even 75% on fast prints to avoid error 120 (buffer collapse). Hope others enjoy them too.
    The feature of skipping having to tap "Start print" on the Palette was also much needed. Great job!
    @jonny yeu: is there any documentation on the plug-in? I'd love to be able to push the ping values and number of splices into my home automation (Hass.io) for easy remote monitoring and automation (e.g.: if last splice done, then increase feed rate).

    Thanks for the kind words! We don't have any official documentation for the plugin, but if you'd like to e-mail me (jonny@mosaicmfg.com) with information that you would require for your setup, I can ask our CANVAS Hub team to see if they can provide details to you.
