Update\Upgrade everything to the newest versions with the following commands (press 'y' when prompted). The Pi will prompt for the default pw, which is "raspberry", then ask you to enter your own pw twice. On first login, you should change the pw from default to the pw of your choice. When you connect it will say "login as:", use the default username "pi" and the password "raspberry". If you get a pop-up saying "The server's host key is not cached", just click "Yes". We will change this Hostname for this device later. If you setup your wpa_nf correctly, it should connect to your network and be assigned an IP address automatically.Ģ.) Log into your Pi with an SSH client, such as Putty, using the default hostname "raspberrypi" (if you have another Pi on your network with this default Hostname, you may have conflicts). Safely Eject the and then remove the Micro SD from your PC and insert it into the Pi ZeroW, then plug power into the Pi (Don't connect the USB to the printer yet). country=USĬtrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev Put the following text in the file (replace your_wifi_ssid and your_wifi_password with your actual SSID and WIfi Password). To setup a Wi-Fi connection on your headless Raspberry Pi, create a text file in the root directory of the microSD card called wpa_nf. When it sees the "ssh" file on its first boot-up, Raspberry Pi OS will automatically enable SSH, which will allow you to access the Pi command line from your PC. To do this, create an empty text file named "ssh" (no file extension) in the root of the directory of the Micro SD card. To connect remotely, you must enable SSH (Secure Socket Shell). Feel free to hookup a monitor and keyboard/mouse if you want to do the setup through the GUI, this guide will list steps to do it remotely so less physical connections are needed. 8Gb minimum, I recommend 16G or 32G because they are cheap.ĭon't remove the Micro SD after the SD card is written, if you want to connect to the Pi to configure it without a monitor and a keyboard attached, you must enable SSH and setup Wifi. There are various tutorials how to do this, so I won't cover it here. (Optional) A nice case for your Pi that you can attach to the back of your printerġ.) Download and install the most current version of Raspberry Pi OS (previously called Raspbian) to micro SD card of your choice. Raspberry Pi Zero W (make sure it's a "W" that has built in wifi)Ī short Micro USB Cable (to connect the Pi to your printer)Ī Micro USB Power Supply (The Pi can be powered from the USB data cable, but I wasn't able to get the Pi to properly boot reliably when powered from my Elegoo Mars. I've created this guide specific to the Elegoo Mars in case anyone else is tired of schleping a USB Stick across their room, or is just looking for a fun project. The tutorial was for use on a Smart TV, but it works just as well on a 3D printer. By patching tsocks as recommended, I was able to send DNS queries out from the Pi Zero over USB.When doing some research on ways to do network printing on my Elegoo Mars, I found a tutorial on how to use a Pi Zero W as a Smart USB flash drive. I found an article about this same issue, which also suggests a fix to the problem. As a result, the SOCKS5 client would only handle IP-based queries, which is not very useful. According to the INSTALL document of tsocks, it should be able to handle DNS queries over TCP protocols when compiled with –enable-socksdns -disable-hostnames, but these compile-time options didn’t help resolve DNS queries. As a workaround, I used port forwarding over SSH to create a SOCKS5 proxy server and used tsocks as a proxy client. Updating the LAN device driver didn’t help. Unfortunately, for whatever reason, I was getting a blue screen of death (BSOD) whenever I enable the Internet connection sharing (ICS) option on the host PC running Windows 7 and connect to the Pi Zero over USB. One comment in the article suggests how to share the host PC’s Internet with the Pi Zero. One problem with this setting is that the Pi Zero doesn’t have an outgoing Internet connection, so I can only get into it through SSH and cannot come out to the Internet from there.
