Most of these services are cloud-based and geographically distributed, meaning that the underlying IP address
ranges are fairly broad and can change over time, while the hostnames remain the same. This flexibility allows
Eiger to maintain a higher level of availability and performance, and this mechanism is common for many cloud-
based applications you already use and trust.
PRINTER TIME SYNCHRONIZATION
Markforged products require accurate system time for securing HTTPS connections to Eiger and other
services; the SSL certificates used to ensure the authenticity of these services have time-limited validity, and
the printer’s time must fall within this window.
Currently, NTP — Network Time Protocol, on UDP port 123 — is the only supported mechanism for time
synchronization, and Markforged printers will attempt to connect to four different servers within the global public
NTP server pool, determined by querying hostnames ending in “.pool.ntp.org”.
Markforged printers also support customer-specified NTP servers. When a printer receives NTP server IP
addresses via DHCP (using DHCP option 042), these addresses will also be used for time synchronization
(connecting to UDP port 123).
BROWSER
Markforged products require the Google Chrome browser. WebSockets must be enabled.
If you are unable to connect to your printer due to network issues, you will still be able to print offline via USB.
