Hi Malcolm,

you can use the G52 command to do this.

If you set G54 as the datum for the first part.

If the second part is at X50.00 Y0.00 and the third part is at X50.00 Y-50.00 and the forth part is at X0.00 Y-50.00 then the code would be.

G21 G40 G17
Etc.

G54 G00 G90 X0 Y0 Z25.
CODE TO MILL FIRST PART
...
G52 X50. Y0 (DO DATUM SHIFT)
G00 X... Y...
CODE FOR SECOND PART (COPY OF FIRST PART)
G52 X0 Y0 (CANCEL DATUM SHIFT)

G52 X50. Y-50. (SECOND DATUM SHIFT)
CODE FOR THIRD PART
G52 X0 Y0

G52 X0 Y-50.
CODE FOR FORTH PART
G52 X0 Y0

Sound as if you should be trying Mach3.

Are you using G41/42, if so have you got a G40 at the end of the program.

Are you cutting inside the shape or outside.

Looking at the code you don't have a lead in or out. Will you post me more detail and a DXF file and I will look into it in more detail.
