Possibly, keep the window open to prevent accumulation of fumes. Otherwise, the risks are low. |

| - | * for a general purpose CNC machine: I am afraid that this table is not really suitable for a general-purpose CNC operation. This is because the linear motors will have a very limited force that they can exert. Hence, I believe that with current motors, metal and wood processing would not be feasible. One could think about installing stronger motors, but really, that would cost a lot. In any case, if we decide to do this, the dust would have to be extracted up to a cleanroom standard (possible, but not cheap) and the noise would be a serious consideration. High-quality spindles (with controlled runout) actually do not create that much noise, but they cost cost cost. | + | * for a general purpose CNC machine: I am afraid that this table is not really suitable for a general-purpose CNC operation.

The noise would be manageable. | + | * for a PCB router: This is much more possible to do. It is possible to build a low power dust extractor from base materials ( i actually have all the parts that I can contribute). The noise would be manageable. We would need to buy in or make a high-quality spindle; budgetary cost is ~200-500gbp. |
| - | * a spark erosion processor: In such case, there is no dust, no noise, and the end product could be of extremely high quality (injection moulds are often finished with this technique). This method is limited by the available electric power, and in general, very slow. EM interference can be managed by enclosing the working area in a Faraday cage. | + | * a spark erosion processor: In such case, there is no dust, no noise, and the end product could be of extremely high quality (injection moulds are often finished with this technique).
