To reflash the board:
1. Plug in the 24V DC power supply
2. Plug in the micro-USB cable into the ET7 controller & a Host Computer with myCNC installed. NOTE: The micro-USB cable must be capable of data transfer (not a simple micro-USB charging cable)
3. Close jumpers J5(reset) & J6(programming) on the controller board
4. Open (remove) the J5 jumper.
5. Open myCNC software on Host computer (Settings > Support Tab)
6. “Select board” set to “myCNC-ET7”
7. Select “Firmware version” from “Release”, “Night build” or “Testing” (“Release” is recommended)
8. “UART port” select port with FT232 attached
9. Baud Rate set to “115200” for ET7; other baudrate can be selected in case of problems on 115200 speed
10. Press “Update Firmware” button, Firmware download and reflashing process will be started
11. If “Sector 0; +” message is shown in the debug window, the reflashing process has finished successfully.
