MKS WIFI for Makerbase Robin: BeePrint web interface with Camera on Flying Bear Ghost – 5

Spread the love

I bought a FlyingBear Ghost 5 with an integrated WiFi module, but I discovered no web interface. I don’t know why they can’t add a basic user interface. Then I went to see the web interface of the high-end Makerbase cards and realized that it was better they didn’t develop it.

My solution was to modify the firmware to support the Web Socket and develop the Web interface. This feature is compatible with all Makerbase cards with an MKS WiFi module.

Here is the installation and demo video of the BeePrint web interface with MKS WiFi firmware.

Check how to install the firmware in the previous article.

BeePrint the Web Interface for MKS WiFi Mischianti version

I wrote a simple but complete web interface with React/Redux. It’s modular, and you can compose your homepage as you want by selecting which widget you want to add to the homepage. I use this to monitor and manage the printer phase.

After installing the firmware in the root http://<MKS_IP> you can find the new user interface, and you will see the old firmware page to the http://<MKS_IP>/update.

I’ve created a basic set of widgets to ensure a good feature set.

Bed and Extruders temperature managers

These widgets help to monitor and can be used to set the pre-heat temperature.

Temperature charts

A widget to manage fan speed, but no feedback of the action.

File upload and files list

These two widgets help you check and manage your files list, and you can use the File Upload to upload new files.

Printer status

With this widget, you can check the printing progress and put it on pause or stop It.

You can use this widget to control an IP camera; I use an esp32 cam for my purpose. You can check more about that here “ESP32-CAM“.

To get the CAM fully working, I advise changing the CameraWebServer example with flash and CORS so that you can control light directly from the widget.

To power the device, I use a 9v-24v to 5v (quick charge) convert very usefully

You can find here Converter from 9v-24v to USB 5v quick charging

Create your own home page

In all the widgets, you can find the “heart” button,

when you select this button, the widget appears on the initial home page. You can change the position and size of the widgets, and you can save It with the floating button kept

in the bottom right corner.

    Hi, Thank you so much for your work
    It’s very cool and convenient
    I can see in the video that you are loading FBG5_prova.gcode
    Then in the file list widget, we can also observe FBG5_prova.gcode,
    but when i load this file on my printer i get FBG5_P~1.GCO in File list
    Please advise what could be the problem?

    • Hi Legenda,
      I think you had format your SD with wrong filesystem.
      Use standard fat32
      Bye Renzo

      • Legenda374 says:

        Thanks for the quick response, Renzo, I can see on the internet the same problem on ESP3D, many people complain about it, so I was surprised that your solution does not have this problem, but it works the same for me as it does on ESP3D, I will try another sd card and let you know if the problem is gone

      • Legenda374 says:

        Hi, Renzo, I studied a lot of information and marlin source code, the problem is that marlin uses ms dos file system with names 8.3, in order to not create meta for file, you can find it by the key “marlin ms doc 8.3” in google, it does not depend on the memory card and the file system on it, but I could not find a solution to this problem, I’m interested to understand why you do not have this problem, It is very strange, If it’s not difficult, take a look at the longName2DosName method in the lib\mks_ui\wifi_module.cpp file, I assume this is the place where it happens, but if I change something there, I get an error when uploading the file, What marlin repository are you using?

  2. Sascha says:

    Hi Renzo!

    First of all: Great Work! As an UI-Designer I really like your Screens and Interface that you provide in your update.
    Because of that I would like to update my machine as well.

    – ELEGOO Neptune 2
    – MKS Robin Wifi V1.1 Module

    When I open the IP it looks like yours.
    When I upload the new Firmawares NOTHING happen. It tries to load and than give a NO CONNECTION Page.
    After a while the original Page is back.

    What do I do wrong?
    I do exactly like in your Video.

    Please help, as I would like to enjoy your nice Interface.

    Thank you!

  3. Sascha says:

    OK. Both updates now worked
    and I can reach the /update page.

    But when I just put in the IP I get this error:

    {“err”: “404: / NOT FOUND”}

    What do I do wrong?


  4. Sascha Bonneß says:

    It worked!

    Really great… I love it!
    Thank you so much…

    A great mod! Thanks for this!

    I have found a few small bugs. For example, it doesn’t show me the print time correctly and seems to count the minutes in units of 100. So I often see e.g. 1h85min :o)
    The fan speed is also not displayed for me (Kywoo3D with FB Reborn Fork FW).

    Is it somehow possible to just include an existing cgi http stream with the camera? Then I could use an old camera that I still have here.

    Have a nice day and happy printing

    Btw: “Your IP has been flagged as spam/malicious.” Wait .. what? Stupid out-of-date blacklists are a good idear with an shortage of IPv4 adresses … not.

    • Hi Boris,
      Ops, I must check that bug…

      For the fan speed, It’s not displayed because firmware can’t retrieve that.

      The stream of HTTP camera (like the esp32-cam) can be implemented, but I can’t, I don’t have a device like that.

      For the IP/spam malicious, It’s my spam filter, and I must use It because I receive a lot of bots and spam.

      Bye Renzo

  6. Boris says:

    Hello Renzo,

    thank you for your answer. I can understand the spam filter, unfortunately more and more actually good IPv4 addresses end up on the lists due to the more frequent sale. With my ISP this affects complete ranges, although they are now for years in his possession. 🙁

    Regarding the camera, I tried to embed the stream simply as follows, but unfortunately this did not output a picture.


    Does it have to be a finished HTML page that already has the stream embedded? Sorry by the way if I was a bit harsh in my first reply with the IP filter. :-/

    • Hi Boris,
      I understand now, but no, for now, I add only a specified stream from esp32, but soon I’m going to add a generic stream URL so you can use your cam.
      Bye Renzo

      • Boris says:

        Hello Renzo,,

        thank you very much! 🙂


      • Boris says:

        Hello Renzo,

        quick info. Here you can see the bug with the wrong time.

        I’m looking forward to the next release and hope you find the time to tinker with Beeprint. 🙂

        Have a nice day.


        • Boris says:

          Can’t edit, so double post – sorry.

          I have another suggestion for Beeprint. It would be really nice if Beeprint played a sound in the browser at the end of printing to inform the user that the printer is done.

          By the way, I find it incredible that Beeprint runs so smoothly on an ESP32. Thanks again for this great FW.

          • Don’t worry, and My idea was to use an esp32-cam to send an email with a photo of the finished work.

            The Beeprint runs on esp8266, but the UI It’s all in the browser, so the heavy work is demanded to the browser.

            Bye Renzo

        • Hi Boris,
          thanks for adding that issue, I fix It soon.
          Bye Renzo

  7. Egor says:

    Hi Renzo! Can you help me please? I trying configure remote access (with white static IP) to BEEPRINT, but i receive message “printer not connected”. If i connected in local network – have no problem.

    I make port forwarding and use port 80 and static publish IP. May be i does something wrong?

    With best regards. Egor.

  8. Egor says:

    I fixed it. Remote access, in my hardware configuration, work if DMZ and Port Forwarding uses in common.

    Renzo, may be add login logic/interface for security?

  9. Сергей says:

    Hi Renzo, can you tell me why the size of some windows in the browser does not increase? More interested in the camera window, thank you.

  10. Syurev says:

    Hello, Renzo!

    I`ve installed your firmware on MKS Nano 3.1 with MKS Fifi module.
    all works great but code sender wont show any response from printer, however the commands runs fine…

  11. bl4ck1c3 says:

    Thank you for this firmware. Works great on my Tevo Nereus!
    Great job!!

  12. Nikolas F says:

    When use this mod with Marlin 2.1.X (master).
    Load both web interface and wifi bin file using SD Card.
    gcode, position and configuration menù works.
    temperature monitor takes very long.
    SD card operation (delete file, print, and a third one that I do not understand what does) does not works
    upload file and print, upload but it stuck because printer require to press “Confirm” button after upload so print does not start

    Innanzitutto grazie e complimenti per lo splendido lavoro!
    E’ già da parecchio tempo che utilizzo con soddisfazione la tua interfaccia web con la mia FlyingBear Ghost 5 ed ora che mi sto avvicinando al mondo della domotica con Home Assistant, ti volevo chiedere se fossi a conoscenza di qualche sistema per integrare la Ghost 5 con l’hub domotico.
