Static IP Instructions

In this article you will learn how to setup a static IP address

INTRODUCTION

Depending on the demands of your work or home network configuration, it may become necessary for you to set up a static IP address for your printer. To do this you will need to SSH (remotely connect to the printer). Please note that some of the modifications that we will make may cause issues. If you can not connect to the printer or notice any other irregularities after this tutorial we recommend a 60 second hard reset of the printer for a M series printer; the always-on AP mode can be used to recover from network issues with the Ultra One.

WARNING: SSH Remote Access is only meant for advanced users. MakerGear is not responsible for any problems or damage created by the use of SSH to modify your printer.

Requirements:

  • Time
    • 10 - 15 minutes 
  • Hardware
    • MakerGear M3-SE, M3-ID, or Ultra One 3D printer
  • Software - A SSH program:
    • For Windows - PuTTY (PuTTY website)
    • For Linux or OSX - Terminal
  • Prerequisites:

What you'll Learn:

  • How to set up a static IP address
  • How to modify files on the Raspberry PI

Before You begin:

  • Follow the instructions for Enabling SSH
  • Note: These instructions work with both the M3 Series and the U1.  Any commands, settings or directions should use the relevant format ("u1printer1a234" for the U1 hostname, "m3printer12a34" for the M3 hostname, etc.).  Please contact Support if you have any questions.

GETTING STARTED

Step 1

SSH into the printer with standard credentials:

  • Username: pi
  • Password: Printer serial number with all the letters capitalized. 

 

ssh pi@m3printer12a34.local

or

ssh pi@u1printer1a234.local
  • Replace the 12a34 with the last 5 characters of your serial number.
  • Log into your printer by using the Serial number (all letters capitalized) as the password.
pi@m3printer12a34.local's password:

or

pi@u1printer1a234.local's password:

Note: when entering the password, no characters will be displayed.  Once the password has been entered, hit "Enter" to login.

Step 2

Enter "ifconfig" into the terminal to view the current network settings, note current IP ("inet"), Broadcast and Netmask/Mask values:

Note: a U1 or M3 printer may display other network interfaces in this report.  For setting a static IP address for the wired network connection, we only care about the settings for eth0.

Step 3

Next, in the terminal, enter:

sudo nano -B /etc/network/interfaces

 

Nano (a Linux command line text editor) should open, displaying the file with text like this:

 

GNU nano 2.2.6          File: /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

iface eth0 inet dhcp

#allow-hotplug wlan0
#iface wlan0-raspbian inet manual
# wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1-raspbian inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
mapping wlan0
    script /root/bin/map_iface
mapping wlan1
    script /root/bin/map_iface
source /boot/octopi-network.txt

Step 4

Go down to the line that reads "iface eth0 inet dhcp", add a "#" to the front of it.
Now, add a new line, and then enter the values in bold text:

GNU nano 2.2.6           File: /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

#iface eth0 inet dhcp
auto eth0
iface eth0 inet static 
address [target.static.ip.address]
netmask [value.from.ifconfig.Mask]
broadcast [value.from.ifconfig.Bcast]

#allow-hotplug wlan0
#iface wlan0-raspbian inet manual
# wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1-raspbian inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
mapping wlan0
    script /root/bin/map_iface
mapping wlan1
    script /root/bin/map_iface
source /boot/octopi-network.txt

 

Note: indentation is only for clarity - it is not required.

An example:

The results for eth0 from "ifconfig":

inet addr:10.1.1.87 Bcast:10.1.255.255 Mask:255.255.0.0
inet6 addr: fe80::e8ad:3794:3b38:926d/64 Scope:Link 

 So add this section to /etc/network/interfaces:

auto eth0
iface eth0 inet static
 address 10.1.1.240
 netmask 255.255.0.0
 broadcast 10.1.255.255

Step 5

Once entered, press Ctrl+X to Exit, then type "y" to confirm overwriting the current file.

It is critical you use the correct values for your local network, as any misconfiguration here will likely prevent communication on the modified interface. Also, ensure that the static IP address you are attempting to set does not interfere with anything else on the network - preferably choose an address outside of your local DHCP assignment range (many routers allow this to be configured, and some will have a range reserved for non-DHCP clients).

Once you are certain the changes have been made correctly, reboot the system by sending "sudo reboot" in the terminal. The Raspberry Pi should reboot with the new static IP address. It should still be reachable via M3Printer[#####].local, or U1Printer[#####].local.
