I put my fondant on the cake smooth it out and it looks great but over night it will sag on the bottom and I make sure I cut it up enough for it to relax. What am I do wrong?

Wondering how long you are allowing it to settle before you put the fondant on. I level and crumb ice my cakes the day before, and then do the final coat of icing and cover with fondant the next day. I know some rush this process by putting a tile on top of the cake for faster settling. Also some cakes are more sturdy for applying fondant, maybe your cake was too light, its hard to know, but a few ideas. I never have that problem, I do store the completed cake in the refrigerator, so it stays firm.

perhaps it's your cake settling? if you cake settles, the fondant may look like it's sagging, but it's really buckling under the compression.

What kind of fondant are you using?

Commercial fondants have agents in them that help them dry enough once put on the cake that they're not as prone to sagging.

Without those agents, between gravity, cake settling under the weight, and the moisture of the cake in contact with the fondant, sagging over time can be an issue.

I am using Satin Ice. My husband did crumb coat and apply fondant in the same evening.

Your Buttercream is probably too soft. I had Fondant do that one time and the BC was the only thing I did different. Haven't used that BC since and haven't had sagging fondant since.
