Feature request - Add "Keep shutter open" option for z-stack

[GabeK-L]

Hello,

I have been using napari-micromanager to control an IX-81 with CSU-X1 spinning disk. Would it be possible to add in the "Keep shutter open" check box that is available in micromanager so that I can take fast z-stacks? Closing the shutter between each z-acquisition dramatically slows down my system; I have my piezo stage triggered by my camera but I cannot currently take advantage of this if the shutter is closed between each step. Ideally, the shutter would only close between channels, positions, etc.

Thanks! Gabe

yep, it's been added to a new-and-improved MDA widget in https://github.com/pymmcore-plus/pymmcore-widgets/pull/180

that widget hasn't made it's way into napari-micromanager yet. but will soon..

I'll also mention that the underlying engine does have the ability to use hardware sequencing just as in the java micro-manager, but currently it's disabled by default and needs to be opted into. More info here:

https://pymmcore-plus.github.io/pymmcore-plus/guides/mda_engine/#hardware-triggered-sequences

once that becomes more stable and reliable, we'll probably turn it on by default. and will probably add an experimental opt-in to the gui before then

Awesome! Thanks for the quick reply and the info. I will give the MDA widget a try and will keep an eye out for that update.
