If the octopi is connected to the printer usb (MEGA 256 and RAMPS 1.4) some time during homing or bedleveling (bltouch 3.1) the printer shuts down and completly restarts. Disconnecting the octopi usb prevents this.
Octopi updated this past week
Marlin bugfix 2.0.x loaded this last week.
Checked all wiring. Am able to duplicate by adding usb from octopi back. When disconnected no issues.
Marlin has the chatty option enabled
Have not tried
