Looping for Multi Fixture Station

Hello,

I am trying to add a loop into the program for a multifixture station. Due to the tip angles I can only set this up for 3 parts. The tricky part is the station is basically setup at a triangle, meaning in one row there will be 2 parts with the same x axis about 150mm apart and the 3rd station is located in the center offset about 100mm in +y. Z is the same for all 3 stations.

I know this would be easy if all 3 were in a row or if there were 2 rows of 2 equally spaced but unfortunatly this is not the case.

Also, I will need to setup a variable to allo the operator to input how many parts they want to run because they will not always be running all 3, it could be 1 or 2.

Any gurus out there willing to help me out on this?

Maybe you should assign offsets in an if statement ?
Something like
ASSIGN/I=1
DO/
IF I==1
ASSIGN/POS_X=0
ASSIGN/POS_Y=0
END IF
IF I==2
ASSIGN/POS_X=150
ASSIGN/POS_Y=0
END IF
IF I==3
ASSIGN/POS_X=75
ASSIGN/POS_Y=100
END IF
(alignment origin at POS_X POS_Y)
Measure part
ASSIGN/I=I+1
UNTIL /I==3

Thanks JEFMAN. How would I set up the loop to check the 3 unequal stations?

You can also make a program for all 3 parts and put in a "missed point return home" so that you don't have to enter the # of parts...then create a home location for the 2nd fixture, and copy and paste the 1st location part of the program....less steps... Good luck..

In the alignment, at the start , you offset x and y origin with assignments POS_X and POS_Y and it should works.
