Help With Z-Axis Config

What did I do wrong on this Z -Axis configuration?

180mm travel distance. Single limit/home switch at the top.  Positive travels towards switch at the top and negative travels towards the bottom.

[AXIS_Z]
 MAX_VELOCITY = 12.0
 MAX_ACCELERATION = 120.0
 MIN_LIMIT = -180.0
 MAX_LIMIT = 0 
 
 [JOINT_3]
 TYPE = LINEAR
 HOME = 8.0
 FERROR = 10.0
 MIN_FERROR = 1.0
 MAX_VELOCITY = 20.0
 MAX_ACCELERATION = 120.0
 # The values below should be 25% larger than MAX_VELOCITY and MAX_ACCELERATION
 # If using BACKLASH compensation STEPGEN_MAXACCEL should be 100% larger.
 STEPGEN_MAXVEL = 25
 STEPGEN_MAXACCEL = 150.00
 P = 1000.0
 I = 0.0

 MIN_LIMIT = -180.0
 MAX_LIMIT = 0 
 HOME_OFFSET = -3.200000
 HOME_SEARCH_VEL = 2.400000

 HOME_FINAL_VEL = 2.800000

Home must be between  MIN_LIMIT and  MAX_LIMIT

HOME = 8.0 is outside softlimits

 

Ok, the change has been made to HOME from 8 to -8
Now when I start the file run, when it runs the too change line the Z-Axis moves in the positive direct until it hits the limit switch and then stops.

 

Tried that but, it fails immediately when I HOME ALL.

This is what I currently have, the final move which I assume is HOME_FINAL_VEL travels in the plus direction when it should be going to the negative position. I can't tell you how frustrating this is after 4 months of trial and error. However I do appreciate the help!

Worked! 
Thank you so kindly, I appreciate the support.
