Laura, when you say trigger, you are talking about clicking play tool in AlignZLP, am I right ?

After discussion, we decide that the new behavior is caused by a change in standard protocol that uses 0 as threshold for checking if slit has drifted. The settings make it not to check and thus not to send that preset.

I will change the code to specifically allow using check preset instead of current preset for AlignZLP node. However, be advised that all reference nodes such as dose measurement or phase plate conditioning requires the right preset to be sent before testing.

code changed and works

I had to revert this feature because this causes confusion on which preset it will use in the actual call from other nodes that send request preset and it creates a conflict with feature Issue #9489 that must uses proper request preset.
