Ultimaker 3’s current firmware does not allow you to turn the printer LED off.
I sleep with my 3D printer next to my bed, so I need it off.
Here is what you do to turn the LED off
Add this line
M142 r0 g0 b0 w0 after T0
The printer LED will turn off automatically once the nozzle and the build plate reaches its’ temperature.
For video streaming use this URL
For snapshot use this URL
Replace 192.168.0.108 with the printer ip address
You can find the IP address in Network tab on the Ulitmaker 3
You can setup DDNS and port map it to 8080 on your router for your printer camera using a DDNS service.
This will allow you to monitor your prints anywhere in the world.
Here is a quick way of port mapping using your Mac.
#1 Downloaded the app port forwarding wizard for free on the app store
#2 Add your 3d printer camera to the list but clicking the Add.
Enter the internal ip address
#4 Look up your public IP address (public IP address)
Replace “Internal_IP_Address” with with your public IP address.
You can figure out your public IP by googling “what is my ip”
Now you can live stream your printer video anywhere in the world as long as the program is running or you have the DDNS setup.
