That remove the "Printer Ready" message on the LCD, replaced by "Media inserted" |
|
Thanks! I didn't notice due to testing |
|
P.S. What kind of LCD? (ExtUI is affected differently from HD44780.) |
|
I've patched Marlin so ExtUI won't show the "inserted" message when the status changes from 'unknown' to mounted. That should do the trick. |

Problem: SD card detection is handled in the LCD or ExtUI update which means isolated SD card readers don't get auto-mounted unless there is a controller. Also, if both UltraLCD and ExtUI LCD controllers are connected, both of them do SD detection and this may be potentially conflicting.
Solution: This PR moves SD card detection to the
CardReaderclass and UI response to SD events to a separateMarlinUImethod (instead of doing this inMarlinUI::update).
