Starting from firmware version 3.10.1, the Original Prusa MK3/S/+ and MK2.5/S have the option of Dump Memory, which will store the RAM content into the xFlash memory. This can be used for diagnosing unusual system issues.
The Memory dump has important information about your printers, like the serial number and IP address. Sharing this data publicly is not recommended.
To access the feature, go to LCD menu -> Support -> Dump memory. This can be used at any time, even during printing.
Note that the printer will stop for the snapshot and it will take some time to finish, therefore we advise not to use this feature if you are not experiencing any problems.
The only way to get the saved dump from the printer is by connecting the printer to a computer. You can do that using Octoprint, Pronterface, Arduino IDE, or another serial monitor of your choice. Use the following commands via the serial link:
The crash dump to xFlash is active at any time, it is stored in xFlash and can be downloaded even after the system reboot until a new D22 command is sent to the printer.
Since the MK2.5 series does not contain the xFlash, the dump memory cannot be stored, so it needs to be sent to a serial link connection. In order to get the memory dump from the printer, there must be a serial link connection available prior to any dump download. In default, the LCD Menu -> Support -> Dump to serial and crash dump are disabled after printer restart.
To get the dump the following process has to be followed and serial commands used:
In case any strange characters appear on the screen, press the reset button below the LCD knob.
Copy the Dump from the program you used to extract it, and paste it on a simple text editor (e.g. Notepad, Notepad++, Sublime Text). Make sure that the formatting of the text is not lost.
When sending the file, add a clear description of the issue along with it.
