I'm running Octoprint 1.3.12 on OctoPi Version 0.16.0, running on Raspberry Pi 3 Model B Rev 1.2. It is connected to an Ender 5 with a SKR mini E3 control board running 2.0.x Marlin. This combination works well for printing...I've been using it for a couple of weeks, including several multi-hour prints. I can print through Octoprint directly as well as from Cura to Octoprint. I do not see this sort of serial error when printing.
Today I tried to do a PID autotune of the hotend. When I ran the command in the terminal, I got a serial error. This behavior repeats every time I do the autotune. Adding M303 to the long running command list did not help.
Any ideas? Thanks!
