VERY LOW COST DESIGN
GoodEnoughCNC hybrid is built from standard mechanical components and steel profiles, which makes it affordable. Just basic handtools needed for assembly.
Suitable for almost any application referring to the size of material. Because of the modular built the cutting dimensions can be increased with replacing only main structural beams.
Using different machining toolheads - hand-held plasma torch, a spindle, laser or some other tool GoodEnoughCNC hybrid can transform from plasma cutter to cnc mill or laser cutter.
Lighter and simpler to manufacture, the Z axis mechanism does not require milled parts like conventional solutions. We're using standard bearing slide guides available in local hardware store.
Hybrid uses fiber optic cnc machine control system, a solution we developed to get rid of ground loops and interference.
