Minimum Requirements

\end_inset 


\layout Standard

The minimum system to run EMC2 and Ubuntu may vary depending on the exact
 usage.
 Stepper systems in general require faster threads to generate step pulses
 than servo systems.
 Using the Live-CD you can test the software before committing a computer.
 Keep in mind that the Latency Test numbers are more important than the
 processor speed for software step generation.
 More information on the Latency Test is in Section (
\begin_inset LatexCommand \ref{sec:Latency-Test}

\end_inset 

).

Additional information is on the EMC Wiki site:

\end_inset 


\layout Standard

EMC2 and Ubuntu should run reasonably well on a computer with the following
 minimum hardware specification.
 These numbers are not the absolute minimum but will give reasonable performance
 for most stepper systems.
 
\layout Itemize

700 MHz x86 processor (1.2 GHz x86 processor recommended)
\layout Itemize

384 MB of RAM system memory (512 MB up to 1 GB recommended)
\layout Itemize

8 GB of disk space
\layout Itemize

Graphics card capable of 1024x768 resolution
\layout Itemize

A network or Internet connection (optional but great for updates)
\layout Itemize

A sound card (optional)

Laptops
\layout Standard

Laptops are not generally suited to real time software step generation.
 Again a Latency Test ran for an extended time will give you the info you
 need to determine suitability.
\layout Subsection

Video Cards
\layout Standard

If your installation pops up with 800 x 600 screen resolution then most
 likely Ubuntu does not recognize your video card.
 On board video many times cause bad real time performance.
