@o_lampe IT WORKS! I been struggling for weeks I should ask you before. Thanks guys for the excellent job helping people. I just clear the "!" and I can home.

@engikeneer appreciate your short and clear explanation about json files. I was worried because editing config.g file I did not change the json file and was wondering if this is causing the problem. Looks like is not that! I will keep looking for posible mistakes.

@o_lampe Thanks a lot I will try and let you know.

Dear all. Before the post, here a tried very hard to dot this  by myself, but I confess my total ignorance about this new knowledge.

I am a novel  61-year-old just retired. I had been able to arm a 1500 mm x 1500 mm  Chinese CNC frame with a  Duet2 (firmware 3.3), 4 NEMA 23 (23HD56001Y-21B), 24 Volts 60 amps and 12 volts power sources. (12 v running initially an external fan to cool down the duet is working fine)
The original Plan was to go slow, step by step. 
Then first step. 
Just to learn basics, no fans, no hot bed, not bed probe etc. just CNC mode 3 axes. (2 engines on Y axe)
Mechanical movement is OK, I can Control well manually with Duet Control Panel via Wi-Fi (192.168.1.55)

Installed 3 mechanical end stops.
I was happy doing fine then… I GOT STUCK WITH  SOFTWARE, machine settings and files. Originally I used RepRap Configuration Tool but did the settings without real understanding of every point to set . 
The problem: 

1.- Messed up folders and g codes
2.- Unable to home
3.- Trying to home I just got small adjustment in all axes and after that unable to move (homing do not even touching the stops)
4.- I change the g codes but I do not know if I need to change also the JSON files created by RepRap Config Tool. ( I do not know how to change a gcode file to json file)
5.- I also erase and redo the config files from various sources - bad idea- many times and start to understand  ( reading a lot ) but I am not good enough yet ( that is why all my code had been mess-up) 


I am sending you a copy from my settings. You will notice many commands that are not need it at this stage, I keep them for future settings but I do not know if they can interfiere with the actual working conditions.
Please be very basic in your answer, I will keep working to improve and understand the proper jargon.

I GOT DESPERATE BUT I AM NOT GOING TO QUIT !
Thanks a lot
