ESC in axis 2.9.0 is that a proper behaviour

github.com/LinuxCNC/linuxcnc/blob/master...sk/taskintf.cc#L1901

Looks likely, and calls:

github.com/LinuxCNC/linuxcnc/blob/master...tion/command.c#L1631

Though that all looks OK. Possibly the issue is that ESC is not calling spindleAbort?

from source,
I don't know how to use git bisect
if you can tell me what to type at the terminal I will do it

The bisect process is fairly simple, but it needs a "good" and a "bad" git tag, and finding the "good" one is something that I can't do until I get back to my LinuxCNC machines next week.

Yes that seems right.
My next thought is that the interpreter state is not changed from m3 to m5
I see a delay in AXIS update of the active gcodes but entering an s either way will start the spindle.
