what should i be looking at for achieving very high accuracy for 3d wood carving? taking the high quality ballscrews and hiwin rails i already have aside, also has anyone been able to achieve 300mm z height cutting space with high accuracy too? my bed frame is made out of 100mmx100mmx5mm mild steel box sections filled with sand and then the gantry is either going to be 2x 160mmx80mm aluminium extrusion in a L shape or thick walled steel rectangle section.
so goals are
to cut wood up to 300mm in height
very high accuracy for 3d models
any advice people?
cheers
