Hello, Newbie here, does the 45 or 60 degree blade need to be oriented in a certain position within the holder before you screw it in, perhaps a peak of 45 blade facing forward? I have been having trouble with rounded text since replacing my first blade (45), did I do it wrong? I followed your excellent directions and don't notice any play, but the fine corners of my text cuts are not right. Appreciations for advice in advance.
