Write CNC12 Info Variables

Description

CNC12 offers 100 internal User-String-Variables that can be used by macros during job execution. The names of these variables are #300 - #399.

If this Property is enabled, the Post Processor will fill User-String-Variables with Information from Fusion 360 that can be used within CNC12. By default, the following information will be written to the job file (click the variable name/number for more details from where in Fusion 360 the information is coming from):

File, Setup and Tool Path Information

Note: In v3 the following changes had to be made: #300 was moved to #330, #301 to #331

Tool Info from the Fusion 360 Tool Library. Updated before each Tool Change in the Post

Feed and Speed Info. Updated before each Tool Change in the Post

Setup Info. Updated for each new Setup in the Post

First 10 Tools made available in variables when both Properties “writeTools” and “writeCNC12Vars” are true and variable name is assigned

Implementation Details

All these CNC12 User-String-Variables are defind at the beginning of the Post Processor around code line #120:

Post Processor Script
...
// Begin Customizable CNC12 User-String-Variables. Valid Numbers #300 - #399 -swissi
//To prevent a parameter of being written to the CNC-File, set the variable name to xyzVar = ""
var writeToolLineVar  = "#300"   // Holds Tool Information from the Fusion 360 Tool Library. Updated before each Tool Change
var designNameVar     = "#301"   // Holds the Fusion 360 Design File Name. Defined at the beginning and does not change
var programNameVar    = "#302"   // Holds the Fusion 360 Program Name/Number as specified in the Post Window
var programCommentVar = "#303"   // Holds the Fusion 360 Program comment as specified in the Post Window
var setupNameVar      = "#304"   // Holds the Fusion 360 Setup Name. Changes for each Setup in the Post
var setupNotesVar     = "#305"   // Holds the Fusion 360 Setup Notes. Changes for each Setup in the Post
var toolPathNameVar   = "#399"   <- Change User-Variable-Number if required
var toolPathNotesVar  = ""       <- This will NOT write this info to the job file
...

As seen on the last two examples on the list above, the name/number of the CNC12 User-String-Variable can be changed should any of these varibales conflict with a variable that’s already been used in other scripts/macros. Just be aware that the example scripts provided here need to be adjusted to the new variable name/number.

Also if some of this information is not needed in a job file, setting the variable name/number to “” will skip that info in the output file. This is an example of a job file:
