Hi
My printer is extremely fast on travel moves. I makes an annoying clacking sound when moving. I want to slow that down, but in the slicer in “Motion ability” that is greyed out and set to 20000. Where and how can I change the value to not clack so loud?
You can check this wiki page：

Although I don’t believe the above answers the question, if you follow the guide you will see an image showing a parameter of 20000, could that be the one you are looking for?
For quieting my U1 for overnight printing, I made a special printer profile. I reduced the maximum acceleration and velocities with SET_VELOCITY_LIMIT (?) as part of the start gcode, and in the specified printer limits for the profile.
Then when I use that profile, it moves more slowly and quietly including during tool changes which went ZIP ZIP ZIP.
I then also modified my END and STOP gcode blocks in the printer’s cfg files to always restore the default speed and acceleration when finished.
Now when I use that profile, it clips all speeds no matter what, including movements not controlled by the slicer.
It means tool changes might take 8 or 10 seconds instead of 5. But for the very thin walls in our apartment, you could hear it in the next room a bit before. And this only adds maybe 30 minutes at most (for hundreds of changes), which I don’t care about overnight.
200mm/s is very quiet, and about what I target as max for best quality printing anyway. Others might be fine with 250mm/s. The 500 it uses by default is clearly audible during tool swaps.
