Returning to 0,0,0

[planekrazie]

I have a question. When I set my 0,0,0 in the middle of my table to cut out a part and I want to take it back to true 0,0,0 ( bottom left corner ).
How do I do it without having to move manualy to the 0,0,0? What I mean is,
I set the zero to my table at the bottom left corner. If I want to cut something sometimes I put the part in the center of the Y. This showes the Y to be at 18". I move the X to 3" and the Z to the top of the part to be machined. I reset everything to zero on the DRO. After the part is finnished I want to move the maching back to the origional position of bottom left not to the place where I zeroed. Can someone help me with this?
Thanks Steve

If you have table zero (machine coords in mach) then go to mdi screen, if your using mach, and type G28, this will send you to machine zero, your job zero will remain in the same place.

Awesome,
Ill have to give it a shot when I get home. Thanks

you need to type G28 x0 y0 z0 to make the machine home all 3 axis.

I didn't have to when I tried it?

You shouldn't need the x0 y0 z0 after G28. Just make sure your machine coordinates are at 0 0 0 in the home position and your limits are active.

ok well maybe it is different in mach.. or if you only need to home one axis you can write the one axis. like g28 y0 for example will only home the y axis.

I tried just g28. Worked like a charm. Thanks Guys. I have been wracking my brain on this for a while.
