Set Up

Let’s Do It

Great, let’s flash an SD card with the image and get to making dust in the shop!

Step 1: Download the image

Download the most recent stable release from github: https://github.com/jeffeb3/v1pi/releases

Step 2: Copy the data to the SD card

The most general option is Etcher: Get Etcher

More details: Burn SD cards with Etcher

Step 3: Configure WiFi (Optional)

If you don’t want to connect this pi to your home WiFi network, then continue to the next step. If you’re not sure, or you want to connect to your home WiFi, look at wifi-setup. Then come right back.

Step 4: Start it for the first time

Safely remove your SD card, or call umount/sync on Linux, and put the card in the pi. Connect the printer and power it up.

The first time the pi boots, it will do some work to expand the filesystem to the full SD card size, and generally setting things up. This takes a few minutes.

Step 5: Connecting

Connect to Hot Spot

Info

  • The default SSID is v1pi
  • The default Password is ChangeMe
  • The default ip is 10.3.141.1. pi is 3.141.
  • The default username/password for RaspAP is admin/secret
  • The Hot Spot will show up with an ssid of v1pi and a connection password of ChangeMe.
  • Your computer might complain that you don’t have an Internet connection. That’s normal. The pi doesn’t have Internet.
  • If you connect with this method, the pi’s ip address is 10.3.141.1
  • Open http://10.3.141.1
  • The RaspAP UI has a username of admin and a password of secret.
  • Change your password! See below.

Connect Through Your WiFi

  • The pi will get it’s IP address from your router. If you know how to find the IP address from your router, then you can do that, and put http://<the ip address> in your browser’s address bar.

  • The pi will also advertise it’s address via http://v1pi.local

  • Macs: Just go there.

  • Linux (including other pi’s): Install avahi-daemon, and then go there.
  • Windows: Check out Adafruit’s guide Here

  • Android: I haven’t got a good way to do this from android, so I would ping v1pi.local from a computer, and see what address it’s pinging, and put that in my android address bar.

  • As a last resort, you can connect a monitor and keyboard. The pi will boot up to a login prompt. The prompt will print the different addresses that will let you connect to the pi.

Step 6: Use it

The landing page will give you a few sparse links to information about this image, and two options:

  • Octoprint: Very mature server for 3D printers. There are a lot of great features, and plugins, but it’s use case is 99% 3D printing.

  • CNC.js: Simple, CNC interface. The Marlin support is especially new, but I’ve been using it with grbl for a long time, and I love how simple and effective it is.

image

  • RaspAP: Administration for the networking on the pi. Be careful, if you’re editing this on the network and you break it, how will you reconnect to fix it? Also, make sure you change the passwords.

Step 7: Change the Passwords

The default login password is raspberry, which the whole world knows. Even if you don’t know how to use the command line, other people do, and they can do nasty things to you. There are many many things to do to improve security, but number one is to change the passwords.

Changing the SSH password

Info

  • The default username is pi
  • The default password is raspberry
  • It is common knowledge, you should really change it.

You’ll need to log into the pi to change the password.

  • Connecting with an ssh client is the easiest way, after you know the ip address.

  • Windows: putty.exe is an oldie and a goodie.

  • Mac/Linux: ssh pi@v1pi.local

  • If you can’t get ssh to work, you can also log in using a keyboard and monitor.

  • The default username is pi and the default password is raspberry
  • Change the password by running the passwd command.
  • There is no root password set, so you don’t have to change it. Any super user actions can be done as pi with the sudo command.

Changing the Hot Spot Password

The hot spot default password is ChangeMe. Any device within range can connect, and find your pi, or the web interface, and control your pi, and your CNC machine. It gets worse if you think about an infected device being in range, and not just a panel van with an antenna on it.

Warning

Be really careful in the “Configure hotspot settings! It will sometimes change the interface, and if you save that, and restart, it will not show up again!

Changing the password is easy, and will help you sleep at night. OK, maybe not, but writing this will help me sleep at night.

  1. Open the webpage: http://10.3.141.1.

  2. Click on Configure hotspot.

  3. Click on Security.

  4. Change the password in the PSK field.

  1. Reboot the pi. The easiest way is the reboot button in the system menu of raspap.

Also in RapsAP, there is the webgui password. Change it in Configure Auth
