Hey there, this is Frank, one of the Customer Success Agents of Mosaic Manufacturing. We hope that you and your family are doing well.
I have noticed that this thread has an interesting discussion with regard to our Palette. Please be advised that we have Ultimaker adapter kits available here: mm3d.co/partstore. An overview of the different kits and instructions can also be found here: mm3d.co/um
Canvas Hub S is not compatible with Ultimaker S5. While UM S5 has a USB port for flash drives, I don't believe that same port can't be used to communicate for printing. Canvas Hub S uses Octoprint, and unfortunately it doesn't appear to be compatible at this time. Do you have other printers available to you that are Canvas Hub S/Octoprint compatible? As long as the printer has a USB port that can be used to send G-Code to, and its communication protocols are non-proprietary, it should be compatible. For Ultimaker 3 it may be possible with some additional configuration, and using a baudrate of 115200 to connect: https://github.com/pbackx/OctoPrint-Um3
