Axis keyboard jogging - not smooth

Hi,

I'm just having a detailed look at the behaviour of LinuxCNC on my system and noticed that jogging via keyboard is not smooth - and this seems to be unrelated to my settings.
G0 / G1 is smooth for the same path with the same feedrate.

So it seems like the simple motion planer is repeatedly running the de-acceleration / acceleration for a short time when it receives jogging requests, at least there seems to be a gap between the requests.

The issue can be covered a little bit by setting the acceleration a little bit slower in the ini file - but it is still there.

Did anyone have a closer look at that already?

Depending upon the desktop used, there may be
settings for keyboard repeats.  These are usually
global settings.

Menu example for xfce4:
Applications/Settings/Keyboard

Alternatively, use commandline xset

With xset, you can disable repeats for indivdual keys.
Use xev to find keycode(s)

Example:
$ xset -r 111

See man page for details:
$ man xset
