Scale are all positive, I put the part ini so you can see the values.

#********************
# Axis Z

[AXIS_2]
TYPE = LINEAR
HOME = 0.0
FERROR = 10.0
MIN_FERROR = 0.5
MAX_VELOCITY = 130
MAX_ACCELERATION = 1000.0
P = 10
I = 0
D = 0.022
FF0 = 0
FF1 = 0.046
FF2 = 0
BIAS = 0
DEADBAND = 0
MAX_OUTPUT = 0
ENCODER_SCALE = 5040
OUTPUT_SCALE = 1
MIN_LIMIT = -140
MAX_LIMIT = 0.01
HOME_OFFSET = 0.0
HOME_SEARCH_VEL = 10
HOME_LATCH_VEL = 1.0
HOME_USE_INDEX = yes
HOME_SEQUENCE = 0
VOLATILE_HOME = 0

then I miss something ... this is the whole part z.

thanks Andy
so I can leave everything so that's fine
