Stepper Configurations
\layout Standard

This section assumes you have done a standard install from the Live CD.
 After installation it is recommended that you connect the computer to the
 Internet and wait for the update manager to pop up and get the latest updates
 for EMC and Ubuntu before continuing.
 For more complex installations see the Integrators Manual.

Latency Test
\layout Standard

The Latency Test tells you if your hardware might cause a problem when running
 real time.
 Some hardware can tie up the processor and cause lateness in responding
 to requests.
 
\layout Standard

Follow the instructions in section (
\begin_inset LatexCommand \ref{sec:Latency-Test}

\end_inset 

) to run the latency test.

\layout Standard

If you have a Sherline or Xylotex you can skip the following sections and
 go straight to the Stepper Config Wizard in Section (
\begin_inset LatexCommand \ref{cha:Stepconf-Wizard}

\end_inset 

).
 EMC has provided quick setup for the Sherline and Xylotex machines.

Drive timing is in nano seconds.
 If your unsure about the timing many popular drives are included in the
 stepper configuration wizard.
 Note some newer Gecko drives have different timing than the original one.
 A list is also on the user maintained EMC wiki site of more drives at:
