You are right, here is a relevant thread on MM github issues: https://github.com/micro-manager/micro-manager/issues/666#issuecomment-452970872
I am not aware of any full implementation of Acquisition Engine in python, depends on what you want to do, you can potentially do that in python.
Here is a demo plugin for using MicroManager in ImJoy: https://github.com/oeway/ImJoy-Plugins/blob/master/repository/microManager.imjoy.html
What we do is to first set the properties, then start an acquisition thread , and run
mmc.startContinuousSequenceAcquisition(0). In the acquisition thread, there is an infinite loop to check remaining images in the ring buffer, if there is any image, we update the display at the moment, but you can add a line to save it with tiffWriter.
You can also try and test the plugin in ImJoy directly: https://imjoy.io/#/app?plugin=oeway/ImJoy-Plugins:MicroManager . After installed the plugin, you can click the plugin icon, choose edit to change the micromanager folder path and configuration file path, then save it, you should be able to get it running. Also notice that you will need to install and run the plugin engine.
