TFT firmware updates are comprised of three elements:
- The firmware binary (
BIGTREE_TFT*_V*.*.*.bin). Example:BIGTREE_TFT35_V3.0.26.1.bin:BIGTREE_TFT_35: modelV3.0: hardware version26.1: software version
- Fonts and Icons (
TFT*folder):TFT*/font: fontsTFT*/bmp: icons
- The config.ini file
Copy the BIGTREE_TFT*_V*.*.*.bin,the TFT*` folder and the config.ini to the root of a blank SD card that is <8GB and formatted as FAT32:
Place SD card with the BIGTREE_TFT*_V*.*.*.bin, theTFT* folder and the config.ini into the TFT's SD card reader and power cycle your printer to start the update process.
A successful update looks like this on the screen:
... and the name of the elements on the SD card changes to this:
After the update is done and the files are renamed, it is possible to reuse them again. To do so, change the name of the element(s) to the pre-update name and start the update process again.
The Firmware can be configured using the config.ini file from from one of these folders:
Copy to SD Card root directory to update or

To edit the config.ini file follow the instruction here: Detailed Instructions here
To update the Firmware configuration:
- Edit the settings in config.ini.
