Hi, I’ve installed a MKS Wifi on my Two Trees printer running Marlin on Robin Nano board.
I’ve loaded Beeprint to my MKS Wifi and it was successful.
I can open the pages, I did setup to my wifi and the interface is working fine.
The problem I have is that when I open the browser it opens a popup at the bottom saying “Printer Connected”, however in all widgets it says “NOT CONNECTED” and every command is disabled.
Is there anything that needs to be done in the printer firmware to make it work?

As an additional information, I’ve tried reloading with beeprint 1.5 and mkswifi 1.2, however I still face the same issue.

sorry for the late response.
I can’t understand what the problem is, can you check the browser console if there are some messages that can help?

I think I have the same problem. I am connected to web UI but it looks like WIFI-BOARD can not connect to Printer_Board.
I can not control my printer, webUI shows that printers is not connected. It is the same in Cura where it connects plugin to wifi board but it says printer is not connected.
I think that there might be some problem with comunication WIFI >>> PRINTER
I use MARLIN on my printer and I enabled serial port but I dont know what speed / baudrate should I set for this serial port …
#define SERIAL_PORT_2 1
//#define BAUDRATE_2 250000 // :[2400, 9600, 19200, 38400, 57600, 115200, 250000, 500000, 1000000] Enable to override BAUDRATE

Beeprint has hardcoded baudrate 115200. I belive we all have the same problem. Beeprint has baudrate 115200 and modern printers have 250000.
I saw on your github that you don´t have time to code button for changing baudrate, but could you tell us what lines should we change in your code to change the hardcoded baudrate? I can´t code but i would be able to compile and flash new version with 250000 baudrate.

thanks for your clarification. So the only 2 options are 115200 and 250000?
Or are there multiple options??

Ok, but by default, can we consider that 90% of all firmware is 115200 and 250000?

Hi, in my Marlin configuration I’ve set the baudrate to 115200 but my printer is “not connected” according to the widgets, while the blue notification in the bottom-right corner says printer connected. I use Marlin 2.1.x bugifix and the latest version of BeePrint

Yes I did. I tried the ESP3D project firmware and it works with my printer. So I don’t think there’s something wrong with Marlin

Hi build a specified version with Serial at 250000, without any dynamic management, I attach the firmware.
Please give me a feedback.

Sorry, but doesn´t work for me.
Beeprint: situation is still the same:“not connected” according to the widgets, while the blue notification in the bottom-right corner says printer connected
Prusaslicer: Could not connect to MKS: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection fail because host has failed to respond (this is a new error).
Cura: Send file to printer failed. Check printer SD card. (also a new error)
Now also does not work with the old marlin (ive checked that for a good measure). Errors are the same except for prusaslicer.
Prusaslicer: “Connection to MKS works correctly” but after clicking ok i get: Error uploading to print host: HTTP 409:409 Conflict.

Still “not connected”. Maybe there’s something wrong in my Marlin firmware?
#define SERIAL_PORT 1 #define BAUDRATE 250000 #define SERIAL_PORT_2 3 #define BAUDRATE_2 250000
Other than that I don’t think there’s something else to activate in Marlin I guess, since as I said ESP3D works with those settings. A feature I like about ESP3D is that it shows you the IP address of the printer on its screen, so you don’t have to search it in the router page. If there’s something else I need to do let me know

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
