Description

• If you have MKS TFT24/35/70, you can use MKS TFT WIFI on MKS TFT24/35/70, don’t need to use ESP3D firmware.
• If you don't have MKS TFT24/35/70 and want to use MKS TFT WIFI on MKS SGEN_L V2, you have to change MKS TFT WIFI 's firmware to ESP3D firmware.
• The difference between MKS TFT WIFI firmware and ESP3D firmware

How to use ESP3D on MKS TFT WIFI

Preparation

• Download bin file tool and install: flash_download_tool
• Download ESP3D firmware: ESP3D firmware bin file
• Download ESP3D Filesystem: index.html.gz
• One USB to serial port module(like CH340, PL2302 and so on)
• Some Dupont wires

Processing method

• 1.MKS TFT WIFI download mode setting

  • WIFI's S1 short circuit
  • WIFI's TX connect to USB to serial port module's TX
  • WIFI's RX connect to USB to serial port module's RX
  • WIFI's GND connect to USB to serial port module's GND
  • WIFI's VCC connect to USB to serial port module's 5V

• 2.Run flash_download_tool and setting

  • Run flash_download_tool -> Select Developer Mode -> Select ESP8266 DownloadTool
  • SPIDownload page settings

  

• 3.ERASE (Erase the original firmware)

  • Click ERASE button, then disconnect and reconnect WIFI's VCC to USB to serial port module's 5V

• 4.START (Download ESP3D WIFI firmware)

  • Click START button, then disconnect and reconnect WIFI's VCC to USB to serial port module's 5V

• 5.Connect ESP3D wifi

  • Disconnect S1, restart the WIFI module, your phone or laptop can detect ESP3D WIFI
  • SSID : ESP3D password : 12345678 Default AP mode
  • Use ladtop connect to ESP3D wifi and Upload ESP3D Filesystem index.html.gz
  • Setting ESP3D to STA mode and connect to your network

• 6.Connect to motherboard

  • Use Dupont wires connect to SGEN_L V2, But the TX RX line needs to be cross-connected(will be fixed next version)

    MKS TFT WIIF                   MKS SGEN_L V2
    VCC            connect to      5V
    GND            connect to      GND
    TXD            connect to      RX3
    RXD            connect to      TX3
    

  • SGNE_L V2 motherboard firmware settings

    • In Configuration.h file

    #define SERIAL_PORT -1
    #define SERIAL_PORT_2 3   // Use MKS SGEN_L V2 serial3
    #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER  // can view the IP address in LCD12864
    

    • In C:\Users\Administrator.platformio\packages\framework-arduino-lpc176x\cores\arduino\HardwareSerial.h file Search :

      } else if (UARTx == LPC_UART3) {                                      
      // Initialize UART2 pin connect                                 
      PinCfg.Funcnum = 1;                                                
      PinCfg.OpenDrain = 0;                                               
      PinCfg.Pinmode = 0;                                                  
      PinCfg.Pinnum = 0;                                              
      PinCfg.Portnum = 0;                                                
      PINSEL_ConfigPin(&PinCfg);                                           
      PinCfg.Pinnum = 1;                                               
      PINSEL_ConfigPin(&PinCfg);                                          
      }                                                     
      

      Change to:

      } else if (UARTx == LPC_UART3) {
      // Initialize UART3 pin connect
      PinCfg.Funcnum = 3;
      PinCfg.OpenDrain = 0;
      PinCfg.Pinmode = 0;
      PinCfg.Pinnum = 28;
      PinCfg.Portnum = 4;
      PINSEL_ConfigPin(&PinCfg);
      PinCfg.Pinnum = 29;
      PINSEL_ConfigPin(&PinCfg);
      }
      

• 7.Connect ESP3D IP

  • Control SGEN_L V2 motherboard by Web
  • Upload gcode file by Web (The actual test is slow, not recommended)
