Ok Here you can find the pictures!

Ok, so are you actually running the Serial Port JSON Server on your computer? Meaning, did you launch it from the command line? It should be running in the background and it hosts a websocket for the browser to connect to. If the JSON Server is running, you should try connecting to localhost then from Chrome.

Ok , maybe now it works, look at the photo, but I don’t know if you see my arduino 1. Thanks for your kindness and for your precious help!!!

I’m guessing your Grbl device is COM8, not COM1.
