thanks, never used a CNC before. it would be used to cut circular stage tops in sectors, ie a 4m diameter stage would be made up in 16 wedge shaped pieces, a bigger stage for example a 9m dia. would be made up of an inner circle 5m dia. from 16 sectors and an outer ring around them of 32 sectors to make the 9m. all in 25mm far eastern plywood. can any router head be fixed to this unit then. does it have the suction bed that hold the sheets down?
