10.1 Setup
Job setup
Three soft keys are available: Tool Table, Message Log, and Install 
Setup, which are used to setup the MILLPWRG2 for operation, and 
programing. 
The Job Setup dialogue is displayed by default when the SETUP key is 
selected.
Job setup
Press the SETUP key to access the Job Setup dialogue.
 
In the Job Setup dialogue there are parameters that can be set which 
the MILLPWR
G2 will default to when not overridden by another 
setting.
Scaling: 
Typically most jobs are scaled at 1 to 1 (full scale).  Occasionally a 
job may be scaled down to as an example 1/2 scale.  In such a case, 
before programming the job, the scale factor should be changed 
here so that it becomes the default scale factor for the program.
Feed Rate: 
The Default setting is the setting that the MILLPWR
G2 will use  
though this setting can change per job, and material used. The 
MILLPWR
G2 will use this as the default in a program unless it is 
changed (for example by a step that is in the program), then that 
new feed rate will be used until changed again.
Feed Rate Override:
The Max field determines the feed potentiometers maximum 
override percentage. The acceptable range is 150% to 200%. The 
last click of the dial will allow the max setting. The second to the 
last click will always be 140%.
The Full Cut field override percentage is applied to a pockets 
programmed feed rate when the tool  makes cuts greater than the 
programmed step over percentage.
Display: 
For Peck/Pass:
The setting can either be in Distance, or Number Of Cycles.
For Stepover:
This defines the step over amount for milling pockets as either a 
percentage of the tool’s diameter or as a distance.
For Angles:
The setting can either be in Degrees or DMS. 
For Res. Inch and Res. MM:
Select the desired display resolution for the DRO display.  
						

							22610 Setup
10.1 Setup
Manual Z: 
Defines the action the DRO takes when a running program 
encounters a manual Z operation. 
The default is Switch to Inc which switches the DRO to INC 
mode. 
The alternative is Do Nothing which performs no action, leaving 
the DRO in whatever mode the user has it in. 
The selected option will be the default for the dialogues and can 
only be changed here in Job Setup.
For Graphics:
The setting can either be set to On to always show the field 
graphic assistant in a step form.
Or set to Automatic for displaying additional fields when available 
in place of the graphic assistant.
Job Clock - Parts Counter: 
For setting the parts counter and stopping or starting the Job Clock.
The Job Clock will provide an estimate of time to machine the part, 
provide a stop watch, parts counter, and overall Job time.
Probing:
When a probe is used, the probe tip radius is entered here. This 
value will be used in dialogues where applicable.
Scale factor
Scale factor is a multiplier that lets you expand or shrink the print’s 
dimensions without performing complex calculations, or affecting the 
proportion of your part. Enter the number that the dimensions should 
be multiplied by, then run the program normally. MILLPWR
G2 will 
adjust the programmed dimensions (but not the tool size) 
automatically.
Scale factor is limited to a range of 0.1” to 10.0”. 
The MILLPWR
G2 scale default setting is 1.0000. A value greater than 
1.0000 will increase the part’s dimensions; a value less than 1.0000 
will reduce them. This is saved to the configuration block and will be 
remembered until it is changed to a new setting.
MILLPWR
G2 will display the current scale factor in the status bar at the 
top of the display screen.
To change the scale factor
In Job Setup, highlight the Scaling field, and enter the multiplication 
factor.
Press the USE key.

to be applied to the feed rate when making full cuts in pocket steps.
Display 
When drilling a hole, the Number of Cycles refers to the number of 
times the drill retracts to clear the debris from the hole.  If Distance is 
used instead, it would mean how deep the drill plunges before it 
retracts.
Similarly, if milling, and using a flat end mill, Distance will mean the 
depth of each pass.  Number of Cycles will mean how many times the 
end mill make a pass, cutting material away each time.
Highlight the Peck/Pass field, and enter either the Number of Cycles 
or the Distance between each cut. This applies to the Z axis depth 
of cut. 
Highlight the Stepover field, and enter either the Percentage of the 
of the tool’s diameter, or a Distance to be used for milling pockets.
Highlight the Angles field and select Degrees, or DMS.
Highlight the Res. Inch and Res. MM fields to select the desired 
display resolution for the DRO display. 
Highlight the Manual Z field to define the action the DRO takes 
when a running program and encounters a manual Z operation 
(default is Switch to Inc). This switches the DRO to INC mode or to 
Do Nothing which performs no action, leaving the DRO in whatever 
mode the user has it in. The selected option will be the default for 
the dialogues and can only be changed in Job Setup.
Highlight the Graphics field and set to either On to always show the 
field graphic assistant in a step form or set to Automatic for 
displaying additional fields when available in place of the graphic 
assistant.

Service files
Occasionally, it may be necessary to provide HEIDENHAIN 
Corporation with diagnostic files to document or troubleshoot a 
problem with the machine or user experience.  These are known as 
Service Files.
 The service files are created by pr essing the Log Files soft key and
then pressing the Service Files so ft key (accept the default name
and press the OK soft key). A dialogue appears as the service files
are created. Another dialogue appears once the service files have
been successfully created.
 The service files take le ss than a minute to generate. If the control
software terminates unexpectedl y, the service files will
automatically be generated by the system as well.  Once generated
(automatically or manually), the resulting ZIP file can be found at
V:\service\.
 Automatically generated service files will have the name 
nc_auto_service.zip.

Manually generated service files will have the name service.zip by
default.
 Multiple service files can be generat ed.  When this occurs, existing
ZIP files at V:\service will be re named as service2.zip, service3.zip,
etc. No number at the end of the filename indicates the most
recently generated file (i.e. service.zip).  After that, the lower the
number, the more recent the file (i.e. service1.zip was generated
more recently than service2.zip).
 Use the cut/copy/paste features in  Program Functions  to move the
ZIP to a USB or network drive such that it can be transferred to
HEIDENHAIN Corporation upon request.
To keep the maximum amount of free space available on the internal 
drive, it is advised to delete old service files from the control after they 
have been safely transferred to an external medium.
