Anycubic I3 Mega WIFI mod!!!

thingiverse

Human: Hi, I'm investigating the Trigorilla-Pro ESP01 Port. My printer has a v1.4.0RC23/P3 firmware, It port is for a ESP01 ESP8266 wifi module. The Anycubic on Boot talks to the wifi module with AT commands at 115200bps, sends an AT command to switch at 2.250.000Bps and opens UDP server in port 3000. This is a sniff traffic on port, commands sent from Printer. Boot printer and it sends at 115.200 bauds: - "?????" scrap data - AT+UART_CUR=2250000,8,1,0,0 Sets ESP8266 to change at 2.250.000 bps Then at 2.250.000 bauds printer sends: AT+CIPSTART=4,"UDP","192.168.1.110",8080,3000,2 - Sets ESP8266 a UDP server at port 3000 in multiconnection mode - IP 192.168.1.110 and port 8080 in UDP protocol are Irrelevant. - (Command AT+CWMODE=1 not appears but is necessary send before to accept that command) More things: If I send via Cura console to printer some commands like: Command via cura console: M9005 '"ssid","password"' And receive via ESP8266 port the string: AT+CWSAP="ssid","password”,5,3 Means in AT command, put ESP8266 in mode AP with SSID=SSID and 3=WPA_TKIP password="password", 5=5 channel at 2,4Ghz. Commnad via cura console: M9003 '"ssid","password"' And receive via ESP8266 port the string: AT+CWJAP="ssid","password" Means in AT command, put ESP8266 in Station mode and connect to wireless SSID=SSID and password="password" Ok, go to make some probes. I check the printer AT commands in ESP8266 module with AT firmwares and work fine. Now, connect the ESP8266 to printer and it does not work properly. I think that some commands are needed to perform setup operation correctly. Workaround: Program ESP8266 with Arduino IDE. Simple program, - Puts a UART in 2.250.000dbs - Connects to my wireless network in DHCP - Opens TCP server at port 2000 (such as telnet server) - Creates a text file with gcode commands M9003 or M9005 to set it Investigate to implement in ESP8266 Optoprint protocol to make possible that CURA links to ESP8266 such as an optoprint server. That's all at the moment, advances Please any information are well become, is you have any question please ask me.
