It has been noted that setting such as: DEFAULT_LINEAR_VELOCITY are in the [TRAJ] section rather then the [DISPLAY] section.
It seems stepconf (PNCconf?) has been doing this as well.
Some of the sample INI files have settings that don't make sense.
eg axis.ini has MAX_LINEAR_VELOCITY in the [DISPLAY] section set as 1.2,
but the [AXIS] sections all have max velocities of 5.
We probably should audit linuxcnc to confirm our docs descriptions and then correct the samples and config wizards.
