Maybe you can do something with this.

Everything looks right until I sent the first print. The I got a temperature error and Octoprint disconnected... ever since that happened I get the same error and most of the posts out there do not seem to help much...

I have a Ender 5 Plus with Firmware 1.70.2 BL and Silent Board
