Mark,
I did something similar with my 24TT a while back.
I had made a jig to hold a workpiece on the table, and totally forgot to tell the laser where the workpiece was located. As a result, when the autofocus routine brought the table up, the air assist tube came down onto my jig.......knocking the X-bar out of its track.
The worst part about this ordeal was the fact that a customer was watching! >.<
That was about 2 years ago. Every time I start a job, I still think about that, so it's doubtful that it will ever happen again.
With my feeble mind, I'm much more likely to forget to set the manual focus (ruining a workpiece) than to make sure the path is clear for the plunger. The only time I don't use autofocus is when I need to run a job slightly out of focus.
(There are a couple of other situations, but they're less than 0.5% of the time.) |
