The Original Prusa XL electronic boards have memory, including a dedicated dynamic memory for processing the PNG files, to show an image preview of a model on the printer display. In rare cases, this memory can be fully consumed, with the printer unable to perform any further action: when this happens, the printer will show the message: "Allocation of dynamic buffer for PNG failed - out of memory."
Error name: PNG Buffer Full
Error code: #17508
Restarting the printer is expected to resolve the error, and this is not expected to occur again. In case a restart does not resolve it, please contact our customer support, we will take it from here.
