[Star Wars] Why did the Rebellion never use the Death Star tech?

My wife brought this up yesterday. The Rebellion had access to the Death Star technology. They got the blueprints for both the Death Star 1 and Death Star 2.

We also know that the Death Star's laser can be changed from anywhere to 1% power as seen on Scariff to 100% as we saw with Alderaan. The DS2 was also able to accurately fire a correct burst into a ship in RotJ to destroy a Rebel Corvette. That was no where near 100% power, as only that single ship was destroyed by that shot.

We also know the tech can be miniaturized, as shown in The Last Jedi. According to Finn, the First Order's bunker buster laser was "Miniaturized Death Star Tech." 

Why did the Rebellion, after having the schematics from both the DS1 and DS2 never miniaturize the weapon tech for themselves and put it on their own Corvettes? It didn't need to be the planet destroying kind, but certainly could have had uses for ship-to-ship combat, or hell, X-Wing to AT-AT combat. 

I don't think it could have been a lack of resources, as the Rebellion/New Republic seems to take over a large portion of the galaxy after the defeat of the Empire.

The empire needed the resources of several planets to build the Death Stars. They had research facilities on dozens of others and it took those facilities to miniaturize the technology.

Yes it absolutely was a lack of resources that stopped the Rebellion from using any of that technology.  They were barely able to function not spend time and energy on research, development and overblown technology that didn't pan out. 

After the rebellion the New Republic wouldn't use it because of the negativity associated with it. The Empire killed some 2 billion innocent people on Alderaan with the technology. The Republic didn't want anything to do with that.
