Sorry, I replied badly.
When the probe reads, the program goes out as if it was finished (eg M30) and no error message appears. In fact, the position is correct, with a deviation of 0.02 mm. The tool remains supported on the probe and all manual and MDI controls are enabled. It seems he can not finish the G38.2 command and exit. If, however, I start the program from the beginning, it will be fine until the second tool check is when I have to resume with the command "run from here". No use to program feed-override or feed-per-rev, obviously by default already has a G94. I would have thought of another solution. If the tool is not ok, I could do a python program where to insert the line from which it should start and cut off everything that is before (other than the headers). It seems that by resuming the program from the start and not from a point, the problem does not persist.
