Don't buy Renishaw products , their service and customer attitude stinks , way below zero .
unless your buying with big bucks , and can afford to bin the products , when they can't or won't supply parts for a current product
and they say their parts come under the US could be used in weapons etc , what a load of ballloney , so can a Led & a resistor and a plastic moulding according to them
so just a heads up , as to their real practices
