Note

Source code in this repository contains in the platformio.ini multiple build targets that automatically customize firmware configuration based on desired set of features.

Naming schema

Both PlatformIO build target names and resulting binary filenames follows pattern:

  • Build targets: <printer version>_<board>_<features (optional, might be missing)>
  • Binary filenames for stock board: <printer version>_<board>_<features (optional, might be missing)>-<version>-firmware.hex
  • Binary filenames for BTT boards: <printer version>_<board>_<features (optional, might be missing)>-<version>-firmware.bin

Printer versions

Build Variant Binary Filename Comments
anycubic_mega_zero amz Anycubic Mega Zero V1, 12V power supply
anycubic_mega_zero2 amz2 Anycubic Mega Zero V2, 24V power supply, heated bed
anycubic_mega_se amse Anycubic Mega SE (in development), 24V power supply, heated bed

Boards
