The A4988 drivers will not handle the amount of voltage the DRV8825 can, that is needed for something like a CNC.
If you plan is to use it as a 3D printer, or even a laser it would be fine. You’d only lose resolution. It also depends on the size of your frame footprint. Smaller would be easier, combined with a lighter cnc like a dremel or something.
