BTT E3V3 flashing from SD card
Apologies for the shaky vid . Recording in one hand on a mobile phone isn't easy.
Made this for a guy I'm helping out on Discord and thought Id share in case anybody else finds it useful.
1. Format the SD card ( 16 GB or less)
2. Copy the firmware.bin file onto the SD card
3. In Win10 eject the SD card ( right click select eject from the pull down menu)
4. Power on the control board
5. Insert the SD card
6. Press reset on the control board ( press and hold for 1 sec)
7. After 10 secs you should see the red activity LED go off then come on and start flashing
8. Remove the SD card
9. Read the card on the PC The name should be changed to FIRMWARE.CUR
10. Connect to the computer and in Pronterface ( or Octoprint terminal) send the M502 then M500 command
