    I have seen those last two messages, and when I look at my printer I see it just rebooted! No idea why. Once I start a print, it's fine.

    Hey James, which printer are you trying to use with your CANVAS Hub and Palette 2?

    It is a Wanhao Di3 but I am running repetier firmware on it.

    Just seeing how the Canvas plugin tries to steal that connection I wonder if it is trying to open the serial port the printer is using also when trying to do the smart auto reconnect. I have to disconnect and physically remove the Palette USB from the Hub anytime I was trying to connect to the printer or they would fight each other.

    I find I have to do the same thing. Sometimes it works, mostly everything needs to be turned off, unplugged, and restarted. Multiple times.

    Hey James, could you please turn auto-connect off and see if the same error occurs?

    I ended up switching my rpi repetier server setup to octoprint and added the two modules and it is working fine. Either the Hub doesn't have enough power or there is something wrong with the usb hub board on the pi-zero.
