Hey @eshchari, could you tell me what you saw on the printer screen, Palette screen, and Hub page after the print suddenly stopped? You can also provide an OctoPrint log from the day of the error to support@mosaicmfg.com (instructions here: mm3d.co/octoprint-logs) as this will help us troubleshoot the issue. Thanks!

I have the same problem, I just bought palette pro 2s and canvas hub S. I think the problem is the canvas hub s, here I report the log of the error, this happened twice:
