How can I keep the bed hot when filament is ended

Hello everybody,

I am a newbee on this forum and perhaps my question has already been posted and answerred. Sorry if it is so, and in this case just show me the link.

I have an ender 5 Plus with the Firmware version 1.70.2 BL (and so the the V2.2 motherboard). Everything is fine but I have a problem. When the filament ended, the bed is not heated anymore, it cools and the printed object gets off when resuming printing with a new filament.

Can anyone tell me :slight_smile:

  1. if the last firmware 1.70.3 BL solves this issue or not ?
  2. If adding a line in the GCode like “M140 S[bed0_temperature]” and were to add it
  3. If there is a way to download (and where) the appropriate version of Marlin and to modify it in order to solve the issue.

Thanks a lot in advance.
Regards
