Arduino + Prusa mini

Hello everybody. I have a question. 

Is it possible to connect arduino insed of raspberry pi to my prusa mini?

What should I do to be able to read the printing percentage, printing time remaining? 

I wanted to connect arduino to my server to be able to read this over th internet via app.

Thank you!

RE: Arduino + Prusa mini

The arduino might be able to talk talk to the printer, but I'm not aware of any libraries to make automating stuff easier.  I think if you connect a cable to the micro-usb port on the side, the mini shows up as a serial device, but I'm just guessing based on some stuff I've seen in Cura Slicer.

However, there may be a even easier solution.  You can hook up an ethernet cable directly to the Mini, and then point a browser at its IP address (e.g. 192.168.1.76 or something like that) and it will provide a web page with printing status, bed had nozzle temperatures, etc.  Sadly you can't control the mini from that interface.  I've been meaning to reverse engineer the javascript that it spits out to try to figure out the API for the raw data, but I haven't gotten around to it yet.  Maybe someone already has and I'm not aware of it.

If you don't have a spare ethernet port, or if running CAT 6 to the printer is impractical, then you might be able to use a microcontroller with both ethernet and wifi to create a bridge, though again that's not trivial.

Aaa, ok, i understand. I also had an idea to take data from Ethernet interface, but the problem is still cable, that is kinda far from my printer.

 

I will try to make some experiments with Arduino, may be I will able to get some data. 

 

Thank you!

It is the Prusa MINI connection option to WIFI for advanced users who can programm.

Ok great, I can program). But as I understand, I have to build my own firmware, than break something on prusa's mother board to upload custom firmware, that I don't really want to do.
