Mode
Defines how motions are output.
Choices:Absolute, Incremental Absolute
All motions are defined with respect to the initialization (home) point.
Incremental
All motions are defined with respect to the controller's current position.
Precision
This setting governs the number of decimal places output for many floating point values in the CNC file, including coordinates, kerf values, and feedrates. The actual number of decimal places is governed by the CFF itself.
Choices:Normal, Extra Normal
Output with reduced precision: usually 2 or 3 decimal places.
Extra
Output with enhanced precision: usually 3 or more decimal places.
Example:
If a raw value is 12.34567, it might be output as:
12.35(Normal precision)
12.346(Extra precision)
Units
This setting controls the units used to output the CNC file. Generally speaking, if outputting in "Inches", no conversion value is applied to the output coordinates.
Choices:Inches (in.), Millimeters (mm) Line numbers in CNC
Defines how line numbers are added to output files.
Choices:(None), Every Line, Start of Part (None)
Example: (None) % G70 G91 G00X0.7Y0.51 G41 M21 G01Y0.75 ... Every Line
Line numbers are added to every line of output. Exceptions include comments and the start/end line - containing a single "%".
Example: Every Line
% N1G70 N2G91 N3G00X0.7Y0.51 N4G41 N5M21 N6G01Y0.75 ... Start of Part
Line numbers are inserted before the start of each part or profile - as determined by the CFF.
Example: Start of Part
% G70 G91 N1 G00X0.7Y0.51 G41 M21 G01Y0.75 ...
Line number increment
Defines the increment for line numbers added to output files.
Range:1to100
Recommended Value:1
Example:
% N1G70 N2G91 N3G00X0.7Y0.51 N4G41 N5M21 N6G01Y0.75 ...
Setting the increment to 5 will number the lines 5, 10, 15, ... % N5G70 N10G91 N15G00X0.7Y0.51 N20G41 N25M21 N30G01Y0.75 ...
Note: This setting is active only if Line numbers in CNC is set to something other than "(None)".
Output Files tab CNC file extension
Defines the file extension for CNC files generated by Output CNC.
Before NestMaster begins generating output, it will prompt for a file name in the Output CNC dialog. This dialog provides a default file name that uses the CNC file extension. If multiple nests are output, unique file names will be created automatically.
Example 1:
CNC file extension = cnc
Output a single nest with the name: MyJob.cnc
Output file: MyJob.cnc
Output three nests with the name: MyJob.cnc
Output files: MyJob01.cnc, MyJob02.cnc, MyJob03.cnc
Clear this setting and NestMaster will generate an output file that has no extension. If multiple nests are output, unique file names will be created automatically.
Example 2:
Clear the CNC file extension setting Output a single nest with the name: MyJob
Output file: MyJob
Output three nests with the name: MyJob
Output files: MyJob.N1, MyJob.N2, MyJob.N3
The N# file extension will ensure unique extensions are applied to all nests.
CNC file extension = N#
Output a single nest with the name: MyJob
Output file: MyJob.N1
Output three nests with the name: My Job
Output files: MyJob.N1, MyJob.N2, MyJob.N3
Default output folder
NestMaster will save output files in the folder defined here.
Before NestMaster begins generating output, it will prompt for a file name in the Output CNC dialog. Initially, the output folder will be the Default output folder, but the Output CNC dialog allows you to browse to any folder. If output is saved to a folder other than the default output folder, NestMaster will remember the new folder and use it next time CNC output is generated.
Note: If the specified folder does not exist, a yellow warning symbol ( ) will appear to the left of the field.
Use long file names
Select this setting to allow NestMaster to generate long file names for CNC output files. Clear this setting to limit output file names to 8 characters (commonly known as the DOS 8.3 file naming convention).
Options tab
Include machine parameters in output
Check this setting to enable machine parameters (such as kerf and feed rate) to be inserted into the CNC files as they are output. These parameter values may be specified through the settings page for the cut process.
Scribe first
If this setting is selected, then each nest will be processed in the following order: 1. Complete all scribe profiles on the nest
2. Complete all cut profiles on the nest
If this setting is cleared, then each part on the nest will be fully processed before the next part is started. Profiles within each part are proc- essed in their natural order.
Note: This setting should be selected when cutting with underwater plasma. Normally, very light metal should not have scribing done first - to avoid problems with metal movement.
Stop before scribing
If this setting is selected, code will be inserted to cause the machine to stop before scribing begins.
Note: This setting is activated only when Scribe first is selected.
Stop before cutting
If this setting is selected, code will be inserted to cause the machine to stop before cutting begins.
Return to machine home
When this setting is selected, NestMaster will return the torch to the machine's home point at the end of each nest. If this setting is cleared, the torch will remain in its position at the end of each nest.
Insert part name as comment
Select this setting if a comment should be output in the CNC file before the first profile of each part. This comment typically gives the sequence number of the part and the part name.
Single Part Output tab Part home
When creating output for a single part, this is the home point (or initialization point) that the cutting head starts at before traversing to the first cut, scribe, or punch on that part.
Choices:Same as Machine Home, Lower Left, Upper Left, Lower Right, Upper Right, Center of Region, CAD Origin
The Machine Home is set in the"Machine settings" on page 21or Output Axis pages of your settings. CAD Origin refers to the point of origin set when the CAD file was created.
All choices (except CAD Origin) are set in terms of the rectangular box surrounding the part (including any leads or extensions).
Generate token files during output
If this setting is selected, an MTC token file version of the part will be output to the same location as the CNC file.
Important: CNC Output settings and the Post Processor (CFF)
Certain CNC Output Settings require specific capabilities to be present in the CFF in order to function properly. While many CFFs are already set up for this functionality, it is possible that you may require changes to your CFF before it will work correctly. Please contact Hypertherm for further assistance if you feel you have one of these CFFs.
The settings which activate functionality resident in the CFF are:
l Include machine parameters in output l Line numbers in CNC
l Return to machine home l Insert part name as comment
CFFs may override the values of Mode, Precision, and Units. In addition, the CFF may override the settings in the above list. For example, a CFF may be configured to always output in incremental mode or without the ability to output machine parameters in the CNC file.
