Streaming of Large G-Code Files

runFile

runFile(path:= string)

The size of files that can be executed employing the GST-interpreter is limited. However, sometimes it is required to execute large files that may have been created e.g. by a CAD-program. Therefore, the user has the possibility to execute filestreams of native G-Code.

Executes the plain G-Code that is contained in the G-Code file given by path. The function call returns after all lines in the supplied file have been processed. The function is intended for streaming large G-Code files to the NC-kernel efficiently.

Native G-Code: No Structured Text Allowed Note that the supplied G-Code file must not contain any ST-elements, but only plain G-Code.

A G-Code filestream from file 'myNativeGCodeFile.nc' can be called from a GST-program with the following syntax if the file is in the default directory of the GST interpreter:

!runfile('myNativeGCodeFile.nc');

If the file 'myNativeGCodeFile.nc' is located elsewhere, the file path must also be specified, e.g:

!runfile('C:\myGcodeFolder\machine1\myNativeGCodeFile.nc');
