LoadFile()

void LoadFile ( const char *const file )

pure virtual

Parameters

file	The full path of the file to load. The contents of the file are passed to Load().

This method parses and processes the Gcode program. The program can be run by calling the Run() method.

Exceptions

RsiError

if the program was not parsed or processed successfully, one exception is thrown. Additional RsiError are logged, use a HelperFunctions::CheckErrors() on the Gcode object to get details for each Gcode line number that failed.

Sample Code:

    string gcodeProgram = "G91; Sets the programming mode to RELATIVE\n" +

                      "G3 X1 Y1 I0 J1; Counter clockwise arc with a center point of 0,1,0 and end point of 1,1,0 relative to the current position\n" +
                      "M80; Show how to use an M-code with GcodeCallback!\n";
