This is very interesting, we are planning to.start using linuxcnc some time in near future. We mainly mill organic shapes, such as 3DProcessing scanned head models, the models start as mesh stl models with million a of small triangles we would like to mill at fastest possible speed and can tolerate some error in precision. Do we need to insert g64 on start, or is it by default start in maximum speed mode. or is Mack3 in this case is a better solution?
