I said to uncheck it, what that is doing is entering the value for offset 253 into the G54 offset each time you start. Because you are likely to have 0 for the 253 offset then that is what you will get, ie no G54 offset.

No probs, probably because I said "untick" as thats what we say this side of the pond, where you guys will say uncheck :)

Hello again, I tried  un checking the box to save my fixture but it would not save and I did try saving it in the pull down menu at the top of the mach3 window, and yet it didn't save.

Ok, just to be clear what you are meaning, if you home the machine then jog to where you want zero to be in G54 then zero each axis DRO that will mean you have just set the G54 offset (its the default) You then can close Mach and it will ask if you wish to save the fixture offset, you click OK and next time you start Mach you home and then if you command a move to zero it should go to the previously saved position.
Is that not happening?

I jog my machine to the set coordinates of x7.9303 y 3.3100 that is the machine coordinates and 0,0 work area and I save thes  the fixture set up and when i home the machine it goes to the home position and then and each time I still have to enter the coordinates in the MIDI screen for it to go  G54G00X0Y0 and then it will go to that work area and after I am done I home it back into place and when I am shutting it down it does ask want to save fixture and I click YES but it never does.

Try this to see what happens
Start Mach and home by pressing the Ref All button, your machine should move to the home switches and set machine coords zero. Now either move via MDI or jogging the position you want G54 zero to be then zero the DROs with the button. Close Mach then restart and home and then command a G0X0Y0 and see if it goes to G54 Zero position.
