Unable to connect to mks sbase #473

Closed mike303625 closed 4 years ago

mike303625 commented 4 years ago

esp3d installed and running ok on node mcu8266, I have connected to mks sbase as recommended in the install guide, making sure of the tx and rx connections eg 8266 tx to sbase rx pin. In marlin I have defined second serial port as 0 (tried 1,3 as well and usb port is using -1) which is used for the normal tft screen. When connected, printer does not respond and is not communicating with esp8266, does anyone have any suggestions as to what else to try? My tx and rx are directly connected with no resistors thanks in advance

my apologies this is a question not a bug

luc-github commented 4 years ago

be sure baudrate is same on esp and printer,
if you power mcu by usb be sure esp share gnd with mks
be sure the port is well configured to communicate with printer in fw

If you have a FDTI serial adapter, you can use Arduino IDE's serial monitor to send G-code by RX/TX/Gnd serial port on printer board. Once you confirm the printer board's serial port configured and working, connect your ESP8266. After uploading the ESP3D 2.1 firmware, I immediately conneced it wirelessly to my PC in order to transfer the config files 404.htm, and favicon.ico files wirelessly. I noticed by trial and error, that if my ESP8266 is too close (6 inches or less) to the PC, I was having difficulty connecting with very that strong signal.

@borland1 this is for Marlin FW installed on ESP32 based board using basic WiFi or ESP3DLib (https://github.com/luc-github/ESP3DLib) not ESP3D which is for standalone board

There is no Printer board ESP8266 based and no Marlin FW for ESP8266 boards

any update?

mike303625 commented 4 years ago

just getting back to it, will try direct coms using arduino serial port try to find the uart config on the board! will advise if successful, the esp3d firmware appears to be working ok just not talking to sBase
