Mike,
Lets see if i can be of help.
1. Open Mach Turn, click the AUTO button, in Auto screen and located under the axis position DRO's there is a button "Soft Limits ON and OFF". CLick that button so the box next to it is black and not green. This turns off
any soft limits you may have set up.
2.Click the Quit Load button in the lower right corner of the screen.
You will be taken back to the screen that Mach Turn opens with.
Now click on the Manual button ( takes you to the manual screen ).
- Just jog the carriage to some safe spot like the middle of Z & X travel of the axis.
3A. In the Manual mode screen
Click the Zero World X button and also click the Zero World Z button.
This cancels any fixture offsets that may exist ( like g54, g55 ).
Notice that the DRO's are now zero.
3B. Click the Set Home X and also the Set Home Z. The axis should not go anywhere.
You have just defined to Mach that this is "HOME".
CLick the HOME X and then the HOME Z buttons and also the HOME ALL button.
Nothing happens because you are home!
4. Now jog both axis away from home some distance , say 1" approx.
Note that how far you moved is shown in the DRO's.
5. Now click the HOME All button.The X axis moves to home and then the Z axis will move to home.
Notice that the DRO's are back to 0,0.
So, you can set home anywhere you want it to be. Mach keeps track of the movements / offsets from home
and if you were to type G28 ( return home command ) in the MDI box the axis will always go back to home.
ANALOGY:
Captain Kirk tells Scotty that he's tired of having his crew get lost when they beam down to the planet Earth from the Enterprise.
Scotty say's that will not be a problem any more becuase he has programmed everyones trackiing device such that no matter where they are , all they have to do is hit the G28 key or the home all key and they will be beamed right
back up to the spaceship.
So try # 1 to #5 above and let me know how it went. Then we will continue on with the story.!
