Much of this chapter quotes from a chapater of the Sherline CNC operators
 manual.

\layout Standard

Mini
\begin_inset LatexCommand \index{mini}

\end_inset 

 was designed to be a full screen graphical interface.
 It was first written for the Sherline

 CNC

\end_inset 

 but is available for anyone to use, copy, and distribute under the terms
 of the GPL copyright.
\layout Standard

Rather than popup new windows for each thing that an operator might want
 to do, Mini allows you to display these within the regular screen.
 Parts of this chapter are copied from the instructions that were written
 for that mill by Joe Martin and Ray Henry.

Mini Display for a Running EMC
\layout Standard

\begin_inset Graphics

\end_inset 


\end_inset 

The Mini screen is laid out in several sections.
 (See Figure
\begin_inset LatexCommand \ref{fig:startmini}

\end_inset 

 ) These include a menu across the top, a set of main control buttons just
 below the menu and two rather large columns of information that show the
 state of your machine and allow you to enter commands or programs.
\layout Standard

When you compare figure
\begin_inset LatexCommand \ref{fig:startmini}

\end_inset 

 with figure 
\begin_inset LatexCommand \ref{fig:runmini}

\end_inset 

 you will see many differences.
 In the second figure
\layout Itemize

each axis has been homed -- the display numbers are dark green
\layout Itemize

the EMC mode is auto
\begin_inset LatexCommand \index{Auto}

\end_inset 

 -- the auto button has a light green background
\layout Itemize

the backplotter has been turned on -- backplot
\begin_inset LatexCommand \index{backplot}

\end_inset 

 is visible in the pop-in window
\layout Itemize

the tool path from the program is showing in the display.
 
\layout Standard

Once you start working with Mini you will quickly discover how easily it
 shows the conditions of the EMC and allows you to make changes to it.
\layout Section

Menu Bar
\layout Standard

The first row is the menu bar across the top.
 Here you can configure the screen to display additional information.
 Some of the items in this menu are very different from what you may be
 acustomed to with other programs.
 You should take a few minutes and look under each menu item in order to
 familiarize yourself with the features that are there.
 
\layout Standard

The menu includes each of the following sections and subsections.
 
\layout Description

Program This menu includes both reset and exit functions.
 Reset will return the EMC to the condition that it was in when it started.
 Some startup configuration items like the normal program units can be specified
 in the ini file.
 
\layout Description

View This menu includes several screen elements that can be added so that
 you can see additional information during a run.
 These include
\begin_deeper 
\layout Description

Position_Type This menu item adds a line above the main position displays
 that shows whether the displays are in inches or metric and whether they
 are Machine or Relative location and if they are Actual positions or Commanded
 positions.
 These can be changed using the Settings menu described below.
\layout Description

Tool_Info This adds a line immediately below the main position displays
 that shows which tool has been selected and the length of offset applied.
\layout Description

Offset_Info adds a line immediately below the tool info that shows what
 offsets have been applied.
 This is a total distance for each axis from machine zero.
\layout Description

Show_Restart adds a block of buttons to the right of the program display
 in auto mode.
 These allow the operator to restart a program after an abort or estop.
 These will pop in whenever estop or abort is pressed but can be shows by
 the operator anytime auto mode is active by selecting this menu item.
\layout Description

Hide_Restart removes the block of buttons that control the restart of a
 program that has been aborted or estopped.
\layout Description

Show_Split_Right changes the nature of the right hand column so that it
 shows both mode and pop-in information.
\layout Description

Show_Mode_Full changes the right hand column so that the mode buttons or
 displays fill the entire right side of the screen.
 In manual mode, running with mode full you will see spindle and lube control
 buttons as well as the motion buttons.
\layout Description

Show_Popin_Full changes the right hand column so that the popin fills the
 entire right side of the screen.
\end_deeper 
\layout Description

Settings These menu items allow the operator to control certain parameters
 during a run.
\begin_deeper 
\layout Description

Actual_Position sets the main position displays to actual(machine based)
 values.
\layout Description

Commanded_Position sets the main position displays to the values that they
 were commanded to.
\layout Description

Machine_Position sets the main position displays to the absolute distance
 from where the machine was homed.
\layout Description

Relative_Position sets the main position displays to show the current position
 including any offsets like part zeros that are active.
 For more information on offsets see the chapter on coordinate systems.
\end_deeper 
\layout Description

Info lets you see a number of active things by writing their values into
 the MESSAGE pad.
\begin_deeper 
\layout Description

Program_File will write the currently active program file name.
\layout Description

Editor_File will write the currently active file if the editor pop in is
 active and a file has been selected for editing.
\layout Description

Parameter_File will write the name of the file being used for program parameters.
 You can find more on this in the chapters on offsets and using variables
 for programming.
\layout Description

Tool_File will write the name of the tool file that is being used during
 this run.
\layout Description

Active_G-Codes will write a list of all of the modal program codes that
 are active whenever this item is selected.
 For more information about modal codes see the introductory part programming
 chapter.
\end_deeper 
\layout Description

Help opens a text window pop in that displays the contents of the help file.
\layout Standard

You will notice between the info menu and the help menu there are a set
 of four buttons.
 These are called check buttons because they have a small box that shows
 red if they have been selected.
 These four buttons, Editor, Backplot, Tools, and Offsets pop in each of
 these screens.
 If more than one pop-in is active (button shown as red) you can toggle
 between these pop-ins by right clicking your mouse.
 
\layout Section

Control Button Bar
\layout Standard

Below the menu line is a horizontal line of control buttons.
 These are the primary control buttons for the interface.
 Using these buttons you can change mode from [MANUAL] to [AUTO] to [MDI]
 (Manual Data Input).
 These buttons show a light green background whenever that mode is active.
 
\layout Standard

You can also use the [FEEDHOLD], [ABORT], and [ESTOP] buttons to control
 a programmed move.
 
\layout Subsection

MANUAL
\begin_inset LatexCommand \index{Manual}

\end_inset 


\layout Standard

This button or pressing <F3> sets the EMC to Manual mode and displays an
 abreviated set of buttons the operator can use to issue manual motion commands.
 The labels of the jog buttons change to match the active axis.
 Whenever Show_Mode_Full is active in in manual mode, you will see spindle
 and lube control buttons as well as the motion buttons.
 A keyboard <i> or <I> will switch from continuous jog to incremental jog.
 Pressing that key again will toggle the increment size through the available
 sizes.

\end_inset 


\layout Quotation

A button has been added to designate the present position as the home position.
 We felt that a machine of this type (Sherline 5400) would be simpler to
 operate if it didn't use a machine home position.
 This button will zero out any offsets and will home all axes right where
 they are.
\layout Quotation

Axis focus is important here.
 Notice (in figure 
\begin_inset LatexCommand \ref{fig:startmini}

\end_inset 

) that in manual mode you see a line or
