[Question]How to Send G-code Commands via HTTP API in ESP3D Version 2.x

[userosos]

Hello,
I’m using ESP3D version 2.x and want to send G-code commands like G28 Z and M114 through the HTTP API. I've tried requests in the format http://<IP>/command?cmd=M114, but I keep getting an Invalid command error. Could you clarify the correct way to format these requests for version 2.x? Also, if a password is needed, how do I set and include it in the requests?

Thank you for your help!

Sorry seems there was a typo in https://esp3d.io/ESP3D/Version_2.1.X/documentation/api/
it is not cmd= but commandText=

Work, thx! If i send g-code - M114 (get current coordinate) - it return only ok bit i want get coordinate like in gcode. For example X0 Y0 Z0. Can i do it ftom http request?

http command does only [ESPXXX]Responses not others commands

Printer response go to Web socket

if you want same chanel for query/answer you better use the raw tcp whci has default port 8888

Hmm. How i can use tcp 8888 port? I create connect from node-red (tcp request node) and it has error and i can see answer. I inject to the node M114.

that is depending of you language and API - it is just tcp socket

Hm. I can`t connect to the flow. I can see disconnect.

be sure also 8888 is right port - check your settings in webui

well this is because you are not using ESP3D, you are using ESP3DLib for Marlin so that a big difference
https://esp3d.io/ESP3DLib/Version_1.X/features/

ESP3DLib V1.0 does not have Data port (Telnet) support
So in that case you must use WebSocket to get Marlin responses like done in WebUI
