2. OctoPrint Inital Setup and Configuration

Part 1: Power On

Remember to use a decent power source for the Pi. A random iPhone or iPad charger will not have the ability to sustain the current required for the Pi. Use at lease a 5V 2.4A power brick.

Making the following modification to the USB cable is MANDATORY!!! Ignoring these instructions could fry the printer, or the PI.

1. Plug the Raspberry Pi into the 3D printer using a USB-A to Micro-USB cable.
   1. Take a piece of electrical tape, and use tweezers to cover the 5V power pin as shown in the following image.

      

   2. This prevents backfeeding power to the printer, and providing power to the printer even if the printer is unplugged.
2. Plug the Raspberry Pi into a network port.
   1. Using an Ethernet patch cord, plug the Raspberry Pi's network port into one on the wall. If there is a network switch (hub) in place, plug the Pi into that. 

   2. Only ports marked: "-M", "-L1", "-L2", and "-L3" will provide data to the Pi. DO NOT USE "-V" Ports.

3. Plug the Raspberry Pi into power.
   1. Remember to use a power source with enough capacity for the Pi. Check the top of the page for guidelines.
   2. Plug a camera into the Pi. (Optional)
      
      1. Plug a camera into the Pi using a USB cable or the Pi's ribbon cable interface.

Done! - At this point, wait 6 minutes until following the next steps. 

Part 2: Logging In- Initial Setup

This next section is specifically focused on the Ender 3 V2 w/ Mriscoc Professional Firmware Installed. Any other printer could be damaged.

1. On your web browser (Edge, Chrome, Firefox), enter the website: http://STEM-E3V2-<PRINTERID>.local Remember to change the <PRINTERID> to the one you set while imaging.

   If the aforementioned address did not work, you can try: https://STEM-E3V2-<PRINTERID> -Omitting the ".local"

2. You should be met with this screen. Skip through it and continue until you reach "Access Control".

   

3. Set the username and password to the same as you set in the Raspberry Pi Imager:
   1. Username: stem
   2. Password: STEMROOM6041!!

      

4. Select "Enable Connectivity Check" and move on. Running tests is unnecessary.

    

   

   
   
5. Select "Disable Anonymous Usage Tracking", and press "Next".

   

6. Enable Plugin Blacklist Processing.

   

7. Leave all camera settings default.

   

8. Default Printer Profile: VERY IMPORTANT!!! 
   1. General:
      1. Name: STEM-E3V2-<PRINTERID>
      2. Model: Ender 3 V2
