Hi! I have the same problem! I now had an email exchange with Snapmaker support. I was informed of the following Com-Port structure: I also got the hint that Snapmaker doesn't know if the P3P has the right driver integrated. "I am not sure if your Palette 3 has a CH340 driver, but our machine requires this so it can be recognized on your OS." https://sparks.gogo.co.nz/ch340.html?msc... It must be possible to integrate the appropriate driver via update. Regards, Jan Update (16.04.2022): Hi! Since the new Version of Canvas.io arrived, I tried to connect so the Snapmaker through the website. This is the outcome: The Status never changes to connected. Just the small popup says connected. I hope the error-code might help.
