My question seems simple but I cannot find an answer. I have looked everywhere, perhaps I looking for the wrong thing.

Is there a G or M code command to send the machine to "Home". I want to use it at the end of a program to bring the table all the way forward and to the left to swap parts in the fixture without having to leave the run screen, go to the jog screen, jog the machine, then reload the program.

This seems so simple but I am stumped. Can anyone help?

:cheers:

This how Fanuc work, I don't know about Certurion
G28G91Z0
Y0X0
G90(bring back ABS more safe for the next run.)

Using the “home” routine would be pretty slow compared to a rapid move. I’d just add a rapid move to your unload station from the work offset (G54 or whatever). Can’t be that hard to figure out.

I always use G53 G0 Z0 X0 Y0, G28 works also in milltronics. Usually at the End of my program I take Z rapid to tool change and then just use G53 G0 Y0 to bring the table nearest the operator. By moving only the Y you don't change the X which could make the vise or the fixture of to the side making it harder to change parts.

Thanks Mortek, That's the answer I was looking for. I knew it was simple.

A G32 will do it. I've used it in toolchanges. It retracts the head all the way up. Look it up in the Centurion manual.

don't forget about the end of program screen in conversational. It allows you to put in a home relative position there. 0,0 for what you want and -12,0 for me most of the time.

That's how I found out about the G53 code, by looking at the code converted from the conversational dialog.
