kinda different 1 本来=原来=used to be 我本来是这里的学生=我原来是这里的学生 2 本来想，本来≠原来 wanted to do something that I failed to get it down finally 我本来想来上班的 3 原来=it turns out, 本来can't replace 原来 in this case 原来这个坏事是你做的啊! it turns out you make this bad thing happen

They could use in the same situation, but 原来 has another meaning. E.x.我们本来/原来打算吃中国菜，但是餐厅关门了。（表示最初的计划 originally） 原来你也在这里。（表示结果 turns out）

本來 is much more like originally. 本來今天要去看電影,但下雨就沒去 My original plan was to go to a movie, unfortunately the rain changed my plan. Originally, I was planning to go to a movie. However, the rain changed my plan. 原來 is more like "it turns out that" I talked to Susan today, you know what, it turns out that she went to the same elementary school with me. 我今天和蘇珊聊天，原來她跟我上同一所小學。

Thanks, these are all very helpful! Great examples, too...
