G00 Z does not work

Hello, although I searched for the macros, in the post processor etc., the GOO Z4O lines do not bring up my Z axis before moving X and Y. It works in N0014 but afterward, it no longer moves. 

Can you help me? 

also, when I make a Z zero and I press "go to zero", the zero axis starts moving towards where it was before the Z zero. 

THANKS.

my gcode start like that
G28 G91 Z0.
G90
G28 G91 X0. Y0.
G90

These G28 commands return the axes to their home positions (machine zero) in relative mode (G91) and then switch back to absolute mode (G90).

maybe that the probleme

here a gcode working find on my simcnc done by fusion360

By default,
there is no 'Go to Zero' for Z in SimCNC? Maybe I’m wrong, could you take a screenshot of it?

Voici les photo, 

  • when I do the Z O maneuver (photo 1), the Z indicates 0 (photo 2), then I click on GO To 0 (photo 3), the Z moves and stops at any position (photo 4)
  • Also, when I test my THC, CSmi0/IPs receives the information, but the Z does not move. Or, it should go from top to bottom. photo pin 25/26

In my case, I can't click 'Go XY' if my homing is not done.

Your homing is not completed here; I can see the orange bar under Z.

 

it shloud be green like in that video https://www.youtube.com/watch?v=VRR2ChF2nfs&t=2s

 

Show me it by recording a video showing the simCNC screen.

in the Go to XYZero button script, you must remove the G53. I solved the problem like this.
