Try the USB method using the STM32 Flash Loader software. | | Extruder Motor Runs Backwards | After updating to V1.32 or a custom Marlin, the extruder pushes filament out instead of feeding it in. | Cause: The new firmware has the extruder direction pin defined in reverse. Solution: This is fixed by inverting the E0_DIR setting in the firmware's Configuration.h file and recompiling. | | Compilation Errors | The compilation process in VS Code and PlatformIO fails with numerous error messages. | Cause: Outdated tools or incorrect environment setup. Solution: 1. Ensure your PlatformIO is up to date. 2. Check the official Marlin issues for your specific error. Common errors involve missing build flags or incorrect src_filter paths. | | update.cbd File is Ignored | You place the update.cbd file on the SD card, but the printer boots normally and ignores it. | Cause: Newer official Tronxy firmware has changed the bootloader behavior and no longer reads this file format. Solution: You must use the STM32 Flash Loader tool over USB to install the firmware.bin file instead. |
