Error calling MDI for manual tool change

Hello,
I build my own hmi and generally it works. Now I have a basic issue but I'm not able to understand why: 
 

Positions of X,Y,Z are 10,10,50 and limits for X is min=6 and max=57.
Offset tool I try to load is all zero

When I try to call M6 T1 I get error because the movement goes out of minimum limit for Z.
Can you tell me why?
In my opinion it makes no sense.

G54 offset are all zero..

Help Please.
Bye
Andrea

In the [EMCIO] section of your .ini file do you have a tool change position set?

TOOL_CHANGE_POSITION = ...

What are G53 values?
If you set G54 near a machine limit, it can not move over that limit if you just set G54 to 0.

Basically G53 values are shown in the picture right? They are inside the valide range

That's the reason!!
Removing it I'm able to go ahead.. change tool and so on.
Positions where 0 0 0 so Z wants to go down outside the range that is 6mm.
I want to remove this command because the Z movement, the only I want while working a gcode, is inserted already in the iso by
the post processor I'm using.
Thanks all guys!

Z motion should be on the negative side, seems you have it positive.
What are the max and min values for the Z axis in the ini file?
Max should be near or 0, min should be -100 or -200 or whatever your Z axis can do in mm.

My Z ha limits: min = 6, max = 57
The direction is correct, became negative going down.
But the zero is down not up.. 
I think it should not be a problem right?
I recreated the gui but with old RPI I was using in this way for long time..

If it works for you, it is OK.
Almost always on mills the Z 0 is at the top and goes down in negative direction, that is how most CAM software will output G code.
