Great Asim!

I had not considered that your servo amps might have had an offset.
With low P and I gain this could cause the problem you mentioned.

Hi Jon, Les, Paul, Ray and all other group members!
Finally i was able to fix this home offset problem. I set
the voltage offset values for each axis to stop motion when machine
is in estop_reset condition
following are ini parameters now:

for x axis
OUTPUT_SCALE = 1.000 0.054
previously it was
OUTPUT_SCALE = 1.000 0.000

for y axis
OUTPUT_SCALE = 1.000 0.080
previously it was
OUTPUT_SCALE = 1.000 0.000

for z axis
OUTPUT_SCALE = 1.000 0.0732
previously it was
OUTPUT_SCALE = 1.000 0.000

now when i home each axis the machine cordinates display
0.000 mm ± 0.001 mm

I am thankfull for everyone who contributed in my post
regards

Asim
