Check out the X-Carve from Inventables or the ShapeOko 3 from Carbide 3D. Both machines cost less than $1K, can use the DW611, and are well supported. Both machines use GRBL which is well documented and has code for laser implementation. The Shapeoko 3 is going to be more rigid but isn’t expandable as they don’t sell longer extrusions for it. The X-Carve can be expanded by adding additional lengths of Maker Slide and longer GT2 belts.
I personally have a ShapeOko 2 running a DW660 router. Granted, it’s not the most rigid machine but it’s taken everything I’ve thrown at it, from 3/4" Baltic birch, to mild aluminum, to carbon fiber with excellent results. It’s my go-to machine for small jobs (I have 2ft x 3ft machine based on CNC Router Parts products for bigger jobs.)
Best of luck - let me know if you have any more specific questions.
