It would be great to have an option to enable placing mini/micro machines using the normal entity, like how flow control pipes can be placed via vanilla pipes.

Would make it so you don't have to craft 3x the entities to have all sizes available.

Sorry that it took so long to get back to this, but what behavior did you mean for me to imitate from Flow Control? Did you mean being able to craft the mini/micro variants using just the base entity? While being able to mine up the modified entity (mini/micro) and returning the base entity? As opposed to returning the mini/micro variant instead?

That sounds conceptually similar to a feature I have in More Inserters (makes a long variant of every inserter, craftable with just the base inserter, mining the long variant would return the base inserter), I can certainly add a setting for that

Not sure if this was specifically what you were asking for, but added two settings, one that changes the recipe for mini/micro machines to use the base item, instead of the item's original ingredients, and then a second setting (that only works when the first one is also enabled) that makes it so mining up the mini/micro variant gives you the base entity instead.

Implemented in v9.3.0
