Not knowing how famliar you are with this machine but are you going through the correct start up procedure .Power interupted comes up when machine is first started then push clear button then axis alighnment will come up on screen xyz push yellow button 1 time for each axis thats 3 in total when axises have alighned you should be good to go.Brake will not opperate unless m6 or m25 is programed or big red emergancy stop button is pushed,that little transformer that george talks about on the mt1 board ,gave me hassles with a spindel fault error when we first got our machine ,i was told it is a common fault with these machines after usage they cook.George is extreamly helpfull when it comes to bridgeports and is right on the money with diognostics.regards greg |
