If the max_z_velocity parameter is specified, the maximum movement speed is limited to this value even if max_velocity is greater. For example [max_z_velocity: 50], [max_velocity: 200] here the maximum movement speed is only 50 mm/sec.
This is believed to be a bug, not a feature. If this is a bug, can you please fix it?
Just want to chime in on this topic, as I made that observation about half a year ago as well.
The Klipper documentation says:
max_z_velocity:
# For delta printers this limits the maximum velocity (in mm/s) of
# moves with z axis movement. This setting can be used to reduce the
# maximum speed of up/down moves (which require a higher step rate
# than other moves on a delta printer). The default is to use
# max_velocity for max_z_velocity.
But at the moment it’s definitely not only limiting “up/down moves”. It limits every move.
Especially if you use low values like “50”, it’s noticeable right away, that all the delta moves (even travel moves) are limited to 50mm/s.
There was a fix a couple of weeks ago for Delta printers (commit afd1058a). Make sure you are on the latest version of the code.

Thanks Kevin. I haven’t updates for ~a month, so I’ll give it a try.
