ESP8266 Community Forum

- Wed Jan 06, 2021 11:14 am #90098 i have an anycubic mega s printer.
There is a new card inside called Trigorilla _V0.0.2.
I want to add the ESP8266 (12-E) wifi card to my printer.
I have defined all versions of ESP3D on GitHub to ESP8266 via Arduino IDE and made connections to Trigorilla v0.0.2 board.
However, as soon as I connect the ESP8266 wifi card to the card, my printer locks itself.
It does not perform any command operation from the LED screen of the printer.
I have 4 pins written side by side on the board, TX3 RX3 GND and 5V.
Actually this is a very nice thing because I connect jumper wires directly to the pins of the ESP8266.
I connect the TX-RX, RX-TX, GND-GND, 5V-VIN pins, but as I said, my printer locks itself and at the same time I cannot see any data flow through the ESP3D Interface.
Can anyone make this link help? My printer's brand is Anycubic Mega S, it contains the Trigorilla V0.0.2 card. I have the ESP8266 V3 (12-E) wifi card in my hand.

Anyhow: what firmware did you flash into the ESP, you can't just get any ESP board and connect it to a device (like a printer)?

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
