A video recap of this manual is available on our YouTube channel:
“myCNC” has a built-in “Macros list” editor for creating and editing macros. The main functions of the editor are presented below.
To create a macro, you need to click the “+” icon and in the field that appears, enter the corresponding name of the macro. After confirmation of creation, using the “V” icon, the macro will appear in the list of saved macros. Below is an example of creating a macro named “M222”.
After creating a macro, you can start editing it. To do this, simply select the desired macro and start editing it in the corresponding macro listing window. Below is edit of creating a macro named “M222”. After creating and editing a macro, it must be saved using the “save changes in macro” button
To delete a macro that is not needed, you must select the macro to be deleted and use the function “delete macro”. In the dialog box that appears, you must either confirm or refute the deletion of the macro.
main() (Surface measure) (Tool is placed somewhere above the surface sensor) (Surface Sensor Width is placed into Parameter #5490) G28.2 Z0. (save current z position into Register1.Z (value with Z doesn't matter)) G53 G38.2 Z-10. (move down to z=-10., stop while sensor is pressed) G10 L70 P1 Z#5490 (set current work position as Z=0 (with offset depends on tool sensor width)) G28.5 Z0. (return back to saved Z position in Register1.Z (value with Z doesn't matter))

Quick note: in system macros (especially in which coordinates are reassigned and/or reset), G0 positioning codes must be used.
