It's best to keep the number of boolean operation to the minimum so merge the cuboids together and just do a single subtract (you may be doing this already).

You could try scaling the whole model up e.g. press "200%" a couple of times before doing the subtraction, then scaling down after. That may increase the precision of the cuts.

If you can't get it working, post the model here and I'll have a look.
