List of Ember Commands

When you're accessing Ember via SSH, it's good to know what the firmware is capable of. This article contains a list of all the smith commands, as well as a few general ones. Smith is Ember's printer control application, and it controls both the projector and the motors that move Ember's linear drive and tray.

HOW TO SEND A COMMAND TO SMITH

Example: echo test > /tmp/CommandPipe (projects a test pattern)

 tail -f /var/log/syslog                Show the Ember log
 nano /var/smith/config/settings     Edit the printer settings file (do an echo refresh afterward)
