Info

CNC_RC CncReset(void); This function recovers from errors, exits from a paused state, establishes a connection with the server in case this has not been done yet. CNC_RC CncLoadJob(const char *fileName, int *jobFileLength, int *macroFileLength, int *isLongJob, int *isSuperLongJob, __int64 *sizeInBytes); Loads the job specified by the first parameters. All the others are output arguments, so pass the pointers to the local variables. If your application runs beside the standard GUI, call CncStartRenderGraph() to update the rendering window. CNC_RC CncRunSingleLine(char *text); Runs a line of G-Code or calls a subroutine contained into the macro.cnc file. double CncGetWorkPos2(int axis); Returns the position of the axis specified. Axes are defined in the cnc_types.h as CNC_X_AXIS, CNC_Y_AXIS and so on. Thus, to get the position of the Z axis simply call: CncGetWorkPos2(CNC_Z_AXIS).

4 A complete example Now we are ready to develop a complete application that provides basic features like the following ones: Displaying current coordinates Homing the machine Loading a job Starting / resuming / rewinding the job 4.1 Design the GUI Open the mainwindow.ui form and add the necessary widgets: Play with the properties to see their effects. Now let’s write some codes. In order to read the current position, we need a timer that periodically calls the CncGetWorkPos2() function. To load a job we use the standard file dialog. For this first test I recommend you to run the application beside USBCNC4 so that you can see what is going to happen. To layout properly the widgets, put them first into a container (e.g. Group Box), then use the Lay Out on a Grid command. The same applies to lay out the containers in the form. This is the mainwindow.h code: #ifndef MAINWINDOW_H #define MAINWINDOW_H #include #include #include typedef qint64 _int64; #include "cncapi.h" namespace Ui { class MainWindow; } Femtotech di Marco Trapanese Via Ripamonti, 14 – 22044 Inverigo (CO) tel. 031 5481112 / 347 9431074 fax 031 2280476 info@femtotech.it www.femtotech.it C.F.
