A recent storm left my Voron 2.4 completely unresponsive—black display, no web interface, and zero signs of life. ⚡️❌
Before tearing down the Manta board or throwing money at new parts, I was able to take a deep dive into the logs because the board powered up. Klipper crashed on boot because it lost connection to the toolhead board (EBBCan), leaving the whole machine seemingly paralyzed.
I pulled out a spare board ready to swap it, but the original hardware actually survived! The power drop just wiped the MCU's communication configuration.
All it took was jumping into SSH, running make menuconfig to rebuild the firmware file, flashing it back over CAN, and restarting the system. No hardware swap required! 🛠️🖨️✨
