Hi,
It seems that the pinout Is wrong; put the device on a breadboard and, with an LED, test the single pin output.
Give me feedback RM

[Renzo Mischianti]

No no,
I need the first part of Serial output where the pin initialized are printed.
Bye RM

[Renzo Mischianti]

Please add also the pin initialization part.

Hi Elkez,
I usually use this solution
Emergency power bank homemade

The step-up drain current is from 18650 (you can put more than one in parallel), and the output is 600mha, which I think is sufficient to power the 400T33D, but check with the tester how much the current drains the device.

Hi,
use get configuration sketch and enable the debug.
After that post the output.

Hi,
I think It’s Serial1 not Serial2.
And there isn’t necessary specify the pin of the serial.

Hi Erick,
Do you already try to set the SD filesystem in the external storage?

Hi all,
paste the controller you use to mange It.

Hi all,
Do you have to follow the guide to configure the FTP client?

Hi Carontes,
these 2 files describe the commands sent and received; if you want Beeprint to communicate with Marilin, I think these commands must be changed in the function of the Marilin protocol.
But first of all, you must know the basic usage of NodeJS and its relative programming environment.

Hi,
the message “Wrong UART configuration” signifies that you didn’t create the constructor correctly and that you probably set a pin on the UART configuration.
Use the examples shared with the library with the constructor created for Arduino.

Arduino UNO like
LoRa_E22 e22ttl(4, 5, 3, 7, 6);
Arduino Mega
LoRa_E32 e32ttl100(&Serial2, 3, 7, 6);

You can find other info here

Hi Dark,
scroll up from your link of the guideline, and check the constructor, you set It like an ESP32, but Arduino Mega doesn’t have the possibility to do that.

Hi,
in this file is the command I send to the printer firmware from MKS WiFi
commands.js

and here is where I was processing the response from the printer
realtimeUpdate.js

If the Marilin firmware uses a different protocol, the MKS WiFi can’t communicate, so we must change these commands and keywords to enable communication.

Bye Renzo

[Renzo Mischianti]

Thanks for the feedback.
But can I ask you the procedure to communicate via AT commands.
I see that the AT commands are supported only by a small number of devices.
Bye Renzo

[Renzo Mischianti]

Hi all,
I think the problem isn’t only the baud rate, but the communication protocol also.
So It’s more complex work, but if you can find the protocol and generate the key to do the relative request, I can try to generate a version for your 3D printer.

Here is the protocol info for MKS
