open loop servo tuning.

from linux cnc config picker,

list by interface -> PICO-> univstep-> univstep.

and generated my config files

At least the example univstep.ini has these:

FERROR = 0.0100
MIN_FERROR = 0.001

( these settings would be way too small for a metric machine however )

I'm sorry, i checked they had
FERROR & MIN_FERROR values,
FERROR = 0.010
MIN_FERROR = 0.001
i use my system in mm config.
and open loop, i just want the linux cnc to give pulse and direction to my servo drive.
i tried changing the value
Ferror = 0.1
Min_Ferror = 0.4
rate of error has reduced, but still couldnt get my velocity high.

thanks , i increased the values
but still couldnt get my machine velocity to get high.
is there a way to disable linuxcnc 's PID generator., i just need it to give pulses, my servo drive can handle the PID.

Have increased the max_velocity of axis 1 = 505
pid-max-vel = 506

still not able to achieve my reqd. velocity.
my motor rated rpm is 1500, it looks like it is just running at 150 to 300 max.

Now i'm not getting errors. just velocity is low., PID max vel and max velocity has been increased and still i dont see difference in my servo's speed. it still stands the same

i entering all values of 1 axis which has low velocity below
[traj]
default velocity = 0.167
max_velocity = 100
default acceleration = 30
max acceleration = 500
stepgen maxaccel =750
