Are fees charged on non-leveraged intraday margin trades?

For example, if I open a margin account, but I do not want to use leverage (I want to trade freely without waiting for cash transactions to settle the next day), are there fees charged? How does that work.

Example scenario: I get into a position, then get out of the position, all in a few minutes (scalping). How do fees with non-leveraged margin accounts work in that case?

(n00b here, I’ve used only cash accounts so far)

@trusktr There are three small fees charged by FINRA and the SEC. Those are outlined here. Other than that there are no fees or commissions.
