As the title suggests, can I add my own recipe's to the machines added by this mod? Or is there any KubeJS support planned?

I really like the machines in this mod and I think they can go really well with some other mods too.

Yes, you can add/change/remove recipes by datapacks system. Also all machines supports sequenced assembly recipes, if you need.

KubeJS? I will think about it, maybe in some future update.

Ah, thanks.

Is it an idea to place these in your mod description, or here on GitHub? Im assuming new machines will still be added? I would like to have examples for those too.

Thanks in advance.

Keep up the good work!

New machines are not planned for the near future. Right now I'm focused on adding some utilities to the mod.

I will put some recipes information to the GitHub wiki
