This is a good short run at a big problem. Take a read.
I had the same issue over and over and have discussed it with test readers and editors. The simple truth is it depends on the style of your book. If you have gone in long handed on describing how things work for instance Neal Asher’s Spatterjay series http://theskinner.blogspot.com, then you have to stick with it. Ian Banks of the other hand was a master at non verbalizing how the tech works but using it beautifully.
I think where it goes wrong is when you try to jump between the two, the reader gets frustrated. Also you may up luring the wrong audience for your book.
