Z axis machine coordinate problem

Hi everyone... the machine work fine but if i use the G53 for go to the machine coordinates in the axi Z no work fine... the machine zero no is in the switch of axi Z, are more down... from the switch Z until machine zero there is 4,280 mm if we count the zero as 1 mm
if i want to move the axi Z at position machine -16.000 the axi no go to that position, the position end is -11.720

example:
this picture is when i setup the piece origin in the switch of Z axi

Someone can help my to fix this?

Are you displaying "machine coordinates" or "relative coordinates"
The offset is 1mm and that is the difference between your G92 offset and the G54 offset.

G53 means "go to machine absolute postion" and then the relative position displayed will be that + G54 + G92, which is what you are seeing.

In the ini file, set home to 0 zero.

A non-zero home is quite normal, I don't think that is the problem here, it is combination of G54 and G92 offsets.
