Is it possible to halt the raspberry PI from Marlin LCD screen ?. I use the very latest Octopi and Marlin 1.1.9, custom build for CR10/Ender.
I currently have to halt the PI from either a SSH session or from the web browser, and sometimes you just want to switch the printer on/off without a web page / ssh available. This is to prevent a SD card corruption ..
I can easily add/change Marlin for adaption to ease this option. This wouldl be a very useful option, as it is always possible to destroy your Octopi image and force a re-creation of the image, a grace full shutdown is highly advisable.
