What is the problem?
Prints will halt, with terminal message Serial is non responsive , but indicates ready.
Octoprint complains of serial ready but non-responsive at some time in the print, BUT monitoring the CPU loading, monitored via ssh and htop, it shows that the CPU is near/above max 4X on a RPIv3 quad core.
What did you already try to solve it?
- video off
- safe mode
- pulled SD card and run, fsck -vf , on another computer, -- OK
I have turned off mjpg_streamer via the menu and it's load is eliminated, but the load is still high,( state: non-printing, non connected to printer, serving webpage ) is at 250%, maxed at some point when printing.
mode does not disable video, and menu for stopping is not functional in safe mode, but otherwise, no significant change in load, prior to commencing to print.
- SD card had no issuses from fsck
