41
b. The first line ―3DwiFi:0/1‖ in the configure file is to control the upgrade of the master control program. As the upgrading signal, 0 means ―no need to upgrade‖and 1 for ―upgrad‖.
To be upgraded or not will be detected when the power is on. This signal will be cleared to 0 after every upgrading. If the upgrading is fail, you can re-copy the folder or modify the signal as 1. By doing so, when power on, it will detect that there is a need to upgrade. The upgrading file is 3DWF_Vx.xx.xxx.bin. Wrong file name will lead to upgrading failure or burn an unknown program to the chip.
c. After powering on the printer, if no SD card or configure file is detected, the USB and WiFi indicator will flash rapidly in 3 seconds. If SD card is detected but no upgrading file, the program will directly enter the interface of application program. If it detects there is a need to upgrade, the USB and WiFi indicator will light up for 2-4 seconds to make upgrading before jumping to application program. (In the initial status of the application program, its two indicators flash asynchronously and slowly.)
d. During upgrading, if the voltage is unstable or there is blackout, it will lead to upgrading failure and even worse, ruin the application program. Moreover, there will be no upgrades after recharging. It needs to re-copy the folder or modify the configure file to make upgrading.
42
6.2 Firmware Upgrade for 3D WiFi Module
a. Copy the folder Upgrade3DWF to SD root directory. The folder includes at least three files: the configure file (config.txt) and the firmware that needs to be upgraded(user1.x.x.x.bin and user2.x.x.x.bin, (x means the version number)).
b. The second line ―ESP8266:0/1‖ in the configure file is to control the upgrade of the WiFi module. As the upgrading signal, 0 means don’t need to upgrade and 1 means need to upgrade. To be upgraded or not will be detected when the power is on. This signal will be cleared to 0 after every upgrading. If the upgrading is fail, you can re-copy the folder or modify the signal as 1. By doing so, when powering on, it will detect that there is a need to upgrade. The upgrading file will be recorded after the user1 and user 2 respectively with the format of userx.x.x.x.bin. Wrong file name will lead to upgrading failure or burn an unknown program to the chip. As the upgrading of ESP8266 uses the method of application upgrading application, unknown program burnt in the chip will lead to unpredictable result. It won’t be used again or make any further upgrading.
c. After power on, if no SD card or configure file detected, the USB and WiFi indicator will flash rapidly in 3 seconds. If there is a SD card but no upgrading file detected, the program will jump directly to application program. If it detects there is a need to upgrade, the
43
USB and WiFi indicator will flash rapidly for 15 seconds to make upgrading before jumping to application program. (The initial status of the application program is its two indicators flash asynchronously and slowly). If the indicators flash slowly and simultaneously, it indicates an exception occurred during the upgrading process.
d. During upgrading, if the voltage is unstable or there is blackout, it will lead to upgrading failure. Moreover, there will be no upgrades after recharging. It needs to re-copy the folder or modify the configure file to make upgrading.
