Joe,... you're my hero. I get it.

I didn't think I would be able to understand a stationary head
tracker. Especially from one posting alone.

Just one thing. What makes the axes move at all?
Once centered on the line, why does it follow the line. And witch
way does it go? On a vertical line would it go up or down?

And do you know anything about the rotating head type.
I get how the tracker head sees the line and turns to follow it, but
how is the rotation of the tracker head turned into X and Y outputs?
Is it like the stationary head sensors, but fed by something attached
to the rotating head?

Thanks a million,

Dan,

ISTR that when I would start the burn, I had to manually set it to a preheat
position, manually set X and Y vectors toward an engagement of the pattern
trace AT A DIAGONAL, so it would pick up the line and run from the oblique
angle, rather than the acute. Then, I would mash a button to begin cutting,
and when it had completed the pierce, engage the travel.
