Filament runout detection ( when printer is blocking and communication buffer are full answers.....)

operations1

I load Marlin version 02010000 (BigTreeTech Octopus v 1.1) on my 3D printer which supports filament runout detection with a sensor attached to the printer motherboard. The sensor is a simple endstop switch, the problem is that whenever I start printing after some time a pop-up message comes {(filament run out) & ( Message from your printer ;; when printer is blocking and communication buffer are full answers might not to executed) (purge more) (disable runout)}

 

But it works perfect with normal screen

Sounds like your marlin is handling out of filament with action messages. This is in deed limited to a few answers when the buffer is full. Then marlin can not accept any more messages and only local display works.

Better solution if supported in your marlin config is to switch to host handling for this useing M412

Add this e.g. in start print g-code of server
M412 H1 S1

could work here. But support must be compield into the firmware.
