BeePrint on Robin E3D

[olo2000pm]

Hi. I am from Poland and I am writing on the translator. I apologize for the mistakes.
I am interested in your solution and I have a question, I have Robin E3D v1.1. There is no dedicated socket for wifi on it.
Do you plan to make software for only TX and RX control?

I have an ESP32-DEVKITC V4

Hi olo,
I don’t know that board and to work a wifi module need more pins check
MKS WIFI for Makerbase Robin: boards and how to wiring esp12 & NodeMCU – 1

I think it’s possible but now I don’t check that.

MKS WIFI need an esp8266.

In my opinion, it is not only a matter of connecting additional pins. Marlin firmware does not support MKS_WIFI without LCD display with LVGL libraries. There must be an LVGL display. I have made many attempts to no avail. I think so, maybe I’m wrong. What do you think about it.

Hi Arkadiusz,
I don’t check the firmware, and I don’t know well the board, if you check that I think there wasn’t a way.
But I don’t know if the protocol was the same of standard communication via serial usb.

We must check that possibility and we can go to use that to connect.

Hi all,
Can it be a solution to use a device (like esp32-s2) with USB OTG and connect It directly to the USB like Octoprint???

It is not about physically connecting the wifi adapter to the motherboard.
It is rather software support in the Marlin firmware.
For BeePrint to work with each board, it only needs to work on TX / RX sending
and receiving Gcode. It cannot use the MKS_WIFI protocol.

BeePrint only applies to “some” MKS Robin boards that they use
LVGL graphic libraries mainly connected via the FSMC connector.

At present, the boards produced by MKS have a variety of Wifi adapters and no FSMC,
There are very few FSMC motherboards compared to others.
In my opinion, MKS_WIFI does not work with a board that does not have a display with LVGL libraries.
Boards based on e.g. LPC1768 do not support FSMC. This is what Marlin says when compiling.
MKS_WIFI has its own data transfer protocol. That’s why I consider the display software daemon
oversees send and receive between motherboard and MKS_WIFI adapter.

in brief

 

LVGL must be enabled for MKS_WIFI to work. LVGL must have an LCD connected via FSMC

This is how the Marlin software for the MKS_WIFI adapter was written.

This situation significantly limits the use and popularization of BeePrint software.
I know that you wrote BeePrint with your FlyBear Ghost 5 in mind. I have such a printer myself.

It would be good to develop the BeePrint project and focus on Wifi support only after RX / TX,
just like in OctoPrint.

Sorry, Arkadiusz,
I lost your reply, but in brief, do you have in mind to standardize the protocol of BeePrint?
And how do you intend to connect to the 3D printer?
All suggestion is appreciated; if you have a route to follow, we can think about that.
Bye Renzo

Hello i have find a module tu add wifi on mks tft of sidewinder x2 but i dont Can use thé tft firmware of bigtreetech
Do you have find a solution ?
I think is a issue from tft firmware bigtreetech because i Can use thé same module but flashed with esp3d firmware
If you know wy the bigtreetech firmware dont Work il interesting
Thanks
