Invento cam Postprosessor, how to edit it ????

[Eskolin]

I am using Inventor whit the CAM for making my G-code file..... BUT when I have made the g-code file and uploade it to UCCNC it make som draw's I dont like.
I have made a small video where you can see that aftere I did a "Go to zerro" and hit the "Start" the spindel go directly to my homing, and don care if there is
any fixture in the way when it go home ( result is broken bits)

here a small video of my CNC: https://photos.app.goo.gl/EqfDACjmDCFeXeh3A

the file I use is here:

(1001)
(MACHINE)
( VENDOR AUTODESK)
( DESCRIPTION GENERIC 3-AXIS)
(T1 D=4 CR=0 TAPER=118DEG - ZMIN=-10 - DRILL)
G90 G94 G91.1 G40 G49 G17
G21
G28 G91 Z0
G90
(DRILL1)
M5
M9
T1 M6
S7280 M3
G54
M9
G0 X5.5 Y-9.526
G43 Z15 H1
Z5
G98 G73 X5.5 Y-9.526 Z-10 R5 Q1 F728
X-11 Y0
X5.5 Y9.526
G80
Z15
M9
G28 G91 Z0
G90 G53 X0 Y0
M30

I am a beginner in this and NOT a genius in G-code,, so if there is anyone who can help /guide me how to change the post prosessor
to not go directly to home but led the Z go to 0 before it move and also when I start a job it go down to Z0 and back up.....

Thanks!
