Graphical Display Area
\layout Subsubsection

Coordinate Display
\layout Standard

In the upper-left corner of the program display is the coordinate display.
 It shows the position of the machine.
 To the left of the axis name, an origin symbol (
\begin_inset Graphics
	filename axis-homed.png
	width 1.5ex

\end_inset 

) is shown if the axis has been properly homed.
 To the right of the axis name, a limit symbol (
\begin_inset Graphics
	filename axis-limit.png
	width 2ex

\end_inset 

) is shown if the axis is on one of its limit switches.
\layout Standard

To properly interpret these numbers, refer to the 
\begin_inset Quotes eld
\end_inset 

Position:
\begin_inset Quotes erd
\end_inset 

 indicator in the status bar.
 If the position is 
\begin_inset Quotes eld
\end_inset 

Absolute
\begin_inset Quotes erd
\end_inset 

, then the displayed number is in the machine coordinate system.
 If it is 
\begin_inset Quotes eld
\end_inset 

Relative
\begin_inset Quotes erd
\end_inset 

, then the displayed number is in the offset coordinate system.
 When the coordinates displayed are relative, the display will include a
 cyan 
\begin_inset Quotes eld
\end_inset 

machine origin
\begin_inset Quotes erd
\end_inset 

 marker (
\begin_inset Graphics
	filename axis-machineorigin.png
	width 2ex

\end_inset 

).
 If the position is 
\begin_inset Quotes eld
\end_inset 

Commanded
\begin_inset Quotes erd
\end_inset 

, then it is the ideal position--for instance, the exact coordinate given
 in a 
\family typewriter 
G0
\family default 
 command.
 If it is 
\begin_inset Quotes eld
\end_inset 

Actual
\begin_inset Quotes erd
\end_inset 

, then it is the position the machine has actually been moved to.
 These values can differ for several reasons: Following error, deadband,
 encoder resolution, or step size.
 For instance, if you command a movement to X 0.0033 on your mill, but one
 step of your stepper motor is 0.00125, then the 
\begin_inset Quotes eld
\end_inset 

Commanded
\begin_inset Quotes erd
\end_inset 

 position will be 0.0033 but the 
\begin_inset Quotes eld
\end_inset 

Actual
\begin_inset Quotes erd
\end_inset 

 position will be 0.0025 (2 steps) or 0.00375 (3 steps).

Preview Plot
\begin_inset LatexCommand \index{preview plot}

\end_inset 


\layout Standard

When a file is loaded, a preview of it is shown in the display area.
 Fast moves (such as those produced by the 
\family typewriter 
G0
\family default 
 command) are shown as dotted green lines.
 Moves at a feed rate (such as those produced by the 
\family typewriter 
G1
\family default 
 command) are shown as solid white lines.
 Dwells (such as those produced by the 
\family typewriter 
G4
\family default 
 command) are shown as small 
\begin_inset Quotes eld
\end_inset 

X
\begin_inset Quotes erd
\end_inset 

 marks.
\layout Subsubsection

Program Extents
\begin_inset LatexCommand \index{program extents}

\end_inset 


\layout Standard

The 
\begin_inset Quotes eld
\end_inset 

extents
\begin_inset Quotes erd
\end_inset 

 of the program in each axis are shown.
 At each end, the least or greatest coordinate value is indicated.
 In the middle, the difference between the coordinates is shown.
 In Figure (
\begin_inset LatexCommand \ref{cap:AXIS-Window}

\end_inset 

), the X extent of the file is from 0.00 to 6.92 inches, a total of 6.92 inches.
\layout Standard

When some coordinates exceed the 
\begin_inset Quotes eld
\end_inset 

soft limits
\begin_inset Quotes erd
\end_inset 

 in the .ini file, the relevant dimension is shown in a different color and
 enclosed by a box.
 In Figure (
\begin_inset LatexCommand \ref{cap:Soft-Limit}

\end_inset 

) the maximum soft limit is exceeded on the X axis as indicatated by the
 box surrounding the coordinate value.

Tool Cone
\layout Standard

The location of the tip of the tool is indicated by the 
\begin_inset Quotes eld
\end_inset 

tool cone
\begin_inset Quotes erd
\end_inset 

.
 The cone does not indicate anything about the shape, length, or radius
 of the tool.
\layout Standard

When a tool is loaded (for instance, with the MDI command 
\family typewriter 
T1M6
\family default 
), the cone changes to a cylinder which shows the diameter of the tool given
 in the tool table file.
\layout Subsubsection

Backplot
\layout Standard

When the machine moves, it leaves a trail called the backplot.
 The color of the line indicates the type of motion: Yellow for jogs, faint
 green for rapid movements, red for straight moves at a feed rate, and magenta
 for circular moves at a feed rate.
\layout Subsubsection

Interacting
\layout Standard

By left-clicking on a portion of the preview plot, the line will be highlighted
 in both the graphical and text displays.
 By left-clicking on an empty area, the highlighting will be removed.
\layout Standard

By dragging with the left mouse button pressed, the preview plot will be
 shifted (panned).
\layout Standard

By dragging with shift and the left mouse button pressed, or by dragging
 with the mouse wheel pressed, the preview plot will be rotated.
 When a line is highlighted, the center of rotation is the center of the
 line.
 Otherwise, the center of rotation is the center of the file as a whole.
\layout Standard

By rotating the mouse wheel, or by dragging with the right mouse button
 pressed, or by dragging with control and the left mouse button pressed,
 the preview plot will be zoomed in or out.
\layout Standard

By clicking one of the

\layout Standard

While the machine is turned on but not running a program, the items in the
 
\begin_inset Quotes eld
\end_inset 

Manual Control
\begin_inset Quotes erd
\end_inset 

 tab can be used to move the machining center or turn different parts of
 it on and off.
\layout Standard

When the machine is not turned on, or when a program is running, the manual
 controls are unavailable.
\layout Standard

Many of the items described below are not useful on all machines.
 When AXIS detects that a particular pin is not connected in HAL, the correspond
ing item in the Manual Control tab is removed.
 For instance, if the HAL pin 
\family typewriter 
motion.spindle-brake
\family default 
 is not connected, then the 
\begin_inset Quotes eld
\end_inset

The .ini file setting 
\family typewriter 
[DISPLAY]INCREMENTS
\begin_inset LatexCommand \label{DISPLAY-INCREMENTS}

\end_inset 


\family default 
 can be used to override the default.
 Its value can contain decimal numbers (e.g., 0.1000) or fractional numbers
 (e.g., 1/16), optionally followed by a unit (one of 'cm', 'mm', 'um', 'inch',
 'in', or 'mil').
 If a unit is not specified the machine's native unit is assumed.
 For users who prefer metric units, a good setting might be
\layout LyX-Code

INCREMENTS = 10 um, 50 um, 0.1mm, 0.5mm, 1mm, 5mm, 10 mm
\layout Standard

For users who prefer 
\begin_inset Quotes eld

If your machine has a homing sequence defined, the 
\begin_inset Quotes eld
\end_inset 

Home All
\begin_inset Quotes erd
\end_inset 

 button or the Ctrl-HOME key will send all axes home.
 Otherwise, the button will read 
\begin_inset Quotes eld
\end_inset 

Home
\begin_inset Quotes erd
\end_inset 

, and will send the current axis home.
 Pressing the HOME key sends the current axis home, even if a homing sequence
 is defined.
 Depending on your configuration, homing may just set the axis value to
 be the absolute position 0.0, or it may make the machine move to a specific
 home location through use of 
\begin_inset Quotes eld
\end_inset 

home switches
\begin_inset Quotes erd
\end_inset 

.
 See Homing section of the Integrators Manual for more information on homing.
