+ | ===== CNC.js ===== | ||
+ | i've decided to try CNC.js. I am installing it on a Raspberry PI 3 (because i had one laying around). the idea is, to get the raspberry as close as possible to the grbl to keep the USB cable as short as possible. I've read that communications issues on the USB link cause by interference could cause the hang-ups i saw with UGS. in any case, the size of the raspberry makes it a practical choice anyway :) | ||
+ | |||
+ | so first i installed raspberry OS, there is pre-built rasbperry image from CNC.js but it has not been updated in the last two years, so I decided to go with a manual install. | ||
+ | |||
+ | here are the steps i went through: | ||
+ | |||
+ | [[install_raspbian_on_f2fs_root]] with my script, set wifi and hostname and enable ssh so we don't need to connect a screen to it ever :) | ||
+ | |||
+ | install git | ||
+ | sudo apt update | ||
+ | sudo apt install git | ||
+ | |||
+ | install cncjs with npm which is installed via nvm. basically, just follow the instructions on the [[https:// | ||
+ | |||
+ | create a systemd service that will start cncjs automatically: | ||
+ | sudo nano / | ||
+ | here are the contents of the startup script: | ||
+ | < | ||
+ | [Unit] | ||
+ | Description=CNCjs | ||
+ | |||
+ | [Service] | ||
+ | ExecStart=/ | ||
+ | Restart=always | ||
+ | RestartSec=10 | ||
+ | # Output to syslog | ||
+ | StandardOutput=syslog | ||
+ | StandardError=syslog | ||
+ | SyslogIdentifier=cncjs | ||
+ | User=pi | ||
+ | Group=pi | ||
+ | |||
+ | [Install] | ||
+ | WantedBy=multi-user.target | ||
+ | </ | ||
+ | nwo start it: | ||
+ | sudo systemctl daemon-reload | ||
+ | sudo systemctl --now enable cncjs | ||
+ | systemctl status cncjs | ||
+ | |||
+ | this should show that it's running now and you should be able to access it on port '' | ||
+ | |||
+ | i'm lazy, so i don't want to type that port 8000 all the time, let's add a redirect using '' | ||
+ | |||
+ | < | ||
+ | sudo apt install lighttpd | ||
+ | cd / | ||
+ | sudo nano conf-available/ | ||
+ | </ | ||
+ | put this in there: | ||
+ | < | ||
+ | $HTTP[" | ||
+ | # capture vhost name with regex conditiona -> %0 in redirect pattern | ||
+ | # must be the most inner block to the redirect rule | ||
+ | $HTTP[" | ||
+ | url.redirect = (" | ||
+ | } | ||
+ | } | ||
+ | </ | ||
+ | activate the config and restart the service | ||
+ | cd conf-enabled | ||
+ | sudo ln -s ../ | ||
+ | sudo systemctl restart lighttpd.service | ||
+ | now you should be able to simply access the cncjs gui by entering the hostname of your raspberry in your browser | ||
+ | |||
+ | it prettymuch runs out of the box now. simply connect to it, choose the usb serial interface and hit connect and you are good to go! | ||
+ | |||
+ | in the future i will add an [[http:// | ||
+ | |||
+ | so far i can't get the stream to display, allthough i can access it with vlc or my webbrowser directy. i have two urls for the sub stream: | ||
+ | * http:// | ||
+ | * rtsp:// | ||
+ | |||
+ | neither show up on screen, got to debug that.. i hope it's not trying to re-encode it on the raspberry using ffmpeg which might be missing.. but we will see.. |
