First first sorry for the post in wrong position and for the multiple.
Thanks for your help, but in my robot we pick 2products short bottle and long bottle. We change short bottle supplier and the difference is 10mn. As I made the 10mm offset, it effect to the long bottle either. any idea where to check and find the subroutine which energies the product choose? So to make the 10mm change after that. Excuse me if I say something wrong. Thanks in advance.
