I do believe that you will need a G91 in front of that G28 to send it home.

 

Then add a G90 to you G00 G54 line.

 

That should take care of your problem.

I try your way , i got message Improper G-code.

when i use G28 U0 W0 , It moves back home allright, then M0 stop , then it move to another position to change tool , even the 1st tool of begining of program , T1 same thing , move to another position, spindle start .. weird machine right?

Add "T0000" or "T0100" to your G28 block

 

N75 G28 U0 W0 T0000;

Finally I traight this out .

This control I can not make tool change at referrence 0 , i have to add another tool change position , or they can called start point .

Good and fast : because tool dont have travel back home.

here new program :

00001

G96 S1200 M3 T0101

G0 G54 X4.0 Z4.0 ( AWAY FROM PART)

G0 X0 Z.1
