I have just recently noticed that my head is out of tram on my 3016. This seems to have happened rather suddenly, or I have been blind to it for a long time?
I did a quick sweep of the table in a 6 inch diameter area (was fixtured up, that was all the room I could have at the moment) and the indicator is within about .0002 in the x-axis, but out .0028 in the y.
So, where do I start looking at problems? I know this model has only 4 leveling screws, so you can't tweak the tram in that way. The machine doesn't have any obvious wear, but that's not to say it isn't worn.
This is a 1994 model, but has fairly low hours.
What are the first checks to make here, as far as diagnosing the problem?
