Stepper setup and pncconf

if i move the machine with the arrow key on the keyboard over a longer distance with fast speed (9000mm/min) the axis stops immediatley if i release the arrow key. but then the axis will move a little bit more with a very slow speed. distance is maybe 0.15mm. this takes 1-2 seconds.

is this ok?

would this be better if i change the P value from 100 to 1000?

As I said P should be 1/servo period so 1000 at 1 ms servo thread period

Creeping after a fast move suggests some other bound setting is wrong
(insufficient velocity headroom somewhere for example)

With P=1000 it works without creeping!


the machine is now working:

max Velocity: 9000mm/min (150mm/s)
max acceleration: x axis 6m/s^2, y axis 3m/s^2

is it possible to edit pncconf in a way to be able to set the max velocity to 9000mm/min? the biggest value i can choose is 100 (mm/min)
is there another way as after every change with the pncconf to edit the ini file?

Once you have a working configuration , I would just
edit the INI and HAL files file directly and no longer use PNCCONF
