Quick verdict
The BobsCNC Evo 4 takes a unique approach by using laser-cut birch plywood for its frame, keeping costs low while offering a massive 24x24 inch work area. Unlike budget machines with weak DC spindles, it uses a standard DeWalt trim router (sold separately) for real cutting power. The trade-off is rigidity -- the plywood frame cannot match aluminum or steel. This makes it excellent for sign-making, wood carving, and large-format projects, but completely unsuitable for metal work. The Evo 4 has a loyal following and strong community support.
