Cbeam slide support

want to run 1500mm long acme lead screws ? you can now ! Use 12mm x 3mm aluminium flat bar and slide support on either end of the bar and glue in position , i have used cloth tape on the back of the bar so that it does not rub on c-beam , aluminum sits between the acme nut block and c-beam channel . check your offset of the block /acme nut and bearing supports on either end .
