G38.2 - error handling

moosi

Hi there,

I´m using G38.2 to probe toward a workpiece.
In the case of an error the message is displayed.
How can I react to an error? In my case I want to stop the program, and show a custom message.
Maybe I want to retry the probing move, but in the end I need to abort the gcode.
Is there a way with conditional gcode or so?

thanks for your help.

You can check the result of any standard G Code
https://docs.duet3d.com/User_manual/Reference/Gcode_meta_commands

result int
0 if the last G-, M- or T-command on this input channel was successful, 1 if it returned a warning, 2 if it returned an error, or -1 if it was a blocking M291 message box command that had a Close button, and either the Close button was pressed or the message box timed out. Meta commands do not change 'result'.

G38.2
if result > 0
     abort "Probe failed.  Job cancelled"

Would cancel the job and display a console message
