Dual axes mirror scanning

[CP Miika]

Hi all,

I have been writing a code to control the scanning rate of dual axis mirrors, using PCI-6731.  I wish to scan in the x-direction with a sawtooth function and in the y-direction with a stepwise function.  Each step (referred to as a B-scan) is composed of a number of x-direction points (called A-lines in my code); both of these parameters I set manually.  However, even though my code does work and is scanning, my problem is that I wish to obtain only a certain number of 'runs' of the entire scanning volume, i.e.. a C-scan is (# of A-lines)x(# of B-scans) - I want to be able to control how many times the C-scan area is scanned.

This may seem like a trivial error especially since I already have the code written, but it is very frustrating.  I have tried putting a 'for loop' to control the number of runs in the attached .vi file (originally a while loop initially). Please help!!
