Description
### Description
Hello,
Sorry if there is another thread with another request, but i think, that this one should be helpfull.
Is there any possibility to write last error code or short text as file to SD card log?
If printer has power supply control, there is not much time to read error message before printer turn itself off. Some log on card will give user chance to get error code and hint where is error if print is not finished.
### Feature Workflow
1. Error appears (Thermal runaway or endstop hit during printing, etc.)
2. Printer writes short log file to SD card (1 or 2 lines long file errorlog.txt)
3. Printer shows message on display as usually
4. Printer turns off heaters and shuts down power supply
