we have aquired a hitachi machine(20sII) which has been running in metric, when we ran a prog with G20 (to change to imperial) the T00 workshift figure in the offset page did not convert in the X axis, it just divided the 250mm it was in metric to 25 inches and the machine overtravels in X, is there a parameter or setting you have to change when moving from mm to inches. The T00 figure in x will not let you update it manually (it should be 9.8425")--any help would be appreciated
