Shaper origin fusion 3607/6/2023 Though I remain skeptical that the problem with CNC is the expense of long axes. I wonder if a 3-5 axis might be better done by using servo-actuated brakes to constrain your motion to a desired direction and speed. There's a reason traditional mills are made with thousands of pounds of cast steel, and it's not to make it hard for hobbyists to enter, CNC in wood or plastic is pretty easy, but steel is hugely more difficult. You need precise control of a tool position, and the reason,they're not done by hand more right now is that access to the workpiece and clamping it in place are a huge pain.Ī big problem with handheld CNC is that cutting many materials you'd want to cut requires precise control of your speed, and also requires rather large amounts of force and rigidity. ![]() ![]() Honestly,I wonder if this concept isn't better suited for welding robots and plasma cutters.
