If you come back later to this project, try Teacup and i am confident that it will work, probably even better than grbl, so you could have a 3d printer and a router together like that.
It is always good to have source files of electronics, its much better and clear with those at hand. Perhaps you could try writing to the seller/manufacturer and ask for source files. Worth a try imo.
