Issue:

A way to edit the Post Processor to unlock the Manual NC functions are needed for Fusion, HSMWorks, or Inventor CAM.

Causes:

Some Post Processor (CPS) files aren't programmed to function with Manual NC PassThrough or CallProgram commands.

Solution:

NOTE: This function is not always included in the stock Autodesk Post Processors by default because manually entering code can result in machine crashes. Be careful when using manual code entry to ensure that machine collisions will not be caused by the manually entered code.

To edit the Post Processor (CPS) for Call Program:

Open the CPS in a text editing program like Microsoft Visual Studio Code.
Use a search function to find onManualNC
Add the following code under the case COMMAND_ACTION:

case COMMAND_CALL_PROGRAM: 
writeBlock(mFormat.format(98), "P" + value); 
break;

To edit the CPS for Pass Through:

Open the PCS in a text editing program like Microsoft Visual Studio Code.
Use a search function to find onManualNC.
Add the following code above the onManualNC section:

function onPassThrough(text) {
  var commands = String(text).split(",");
  for (text in commands) {
    writeBlock(commands[text]);
  }
}
