Both flowchart examples contain instances, but none of the example flows work, because there is no metamodel in the unit and hence it cannot be registered.

* org.eclipse.epsilon.examples.egl.flowchart
* org.eclipse.epsilon.examples.etl.flowchart2html

The plugin

org.eclipse.epsilon.eugenia.examples.flowchart

provides a metamodel, but it leads to failures when instantiating the instances.

Any advice on where to find the corresponding MM to make the examples work?

Many of the examples use the metamodels in the examples/org.eclipse.epsilon.examples.metamodels project:

https://git.eclipse.org/c/epsilon/org.eclipse.epsilon.git/tree/examples/org.eclipse.epsilon.examples.metamodels

WIth Epsilon installed, it's usually enough to right-click on the .ecore and use the "Register EPackage" menu item. Hope it helps!

Thanks. I have found it. Still means the the examples do not work out of the box which I assume is the intention when installed into Eclipse. Do you want to file that as a bug?
