any thoughts?

2

@Tiago_Vale I just updated my Pi to the latest commit and it loads fine for me. Delete the node_modules folders and run “npm Install” inside the laserweb folder , then execute laserweb again

3

can I just delete the node_modules folder? Or I have to empty it?

4

Just delete the folder

5

Its working!!! Yeah!!!

6

It seems there is something else.

No laserweb again :(, the strange thing is that the serial port component is compiled instead of downloaded, and its where the fault resides.

pi@octopi ~/LaserWeb3 $ node server-smoothie.js

Sorry Pi is built in the printer
Is the telnet solution working?

10

Why not upload the gcode directly to smooth and then play?

11

Evaluating the connections array

     } else {
            if(typeof connections[i] != "undefined"){
                    connections[i].emit("data", data);
            } else {
                    console.log("COUNT ", connections.length);
            }
     }

prevents the crash but I don’t know whats erasing connections[i] at first time.
