Like really really bad. not only does it cost the same amount of plastic and copper, it also costs basically the same amount of steel in form of liquid and then additionally sand too. You also lose 2 module slots because assembler 3 haves 4 slots and casting machine haves 2. All of that to have 3 second faster crafting time?

Did you maybe intended to have it output 2 or even more low density structures at once?

Could this be revisited pretty please. otherwise loving the mod, makes pure angels much more enjoyable since it didn't have any kind of integration to vanilla other than oil handling side of the game.

The LDS casting (and engine casting) recipe will be removed in the next update. They don't really fit with what I have in mind for casting, and I totally forgot about the Galore LDS one as it's disabled in the space age version I'm working on, and rethinking that one made me rethink the engine recipe as well. Casting recipes should be for low-level intermediates (where prod doesn't matter as much), with their positives being their speed and metal fluid requirement (instead of plates). And as costs for these benefits, they take sand and can use less module slots.

Sorry that I couldn't save them, but thanks for your suggestion nevertheless :D
(Any buildings using these recipes will still continue to operate)

No worries there, i didn't even actually reach that stage yet. i was just looking factoriopedia and planning ahead and noticed that recipe. I lost a bit of motivation when i noticed that jivolite richness is bugged, makes mega bases kinda bad to build so im on hold now waiting for that to be fixed and ill jump straight back then.

No rush though, i can happily wait lol. Thanks
