Re: [CAD_CAM_EDM_DRO] ESTOP vs E's GONE sensor...

That's somewhat the same approach that Lincoln Electric uses to protect
operators of their Robotic Welding Cells. All access is fenced-off, except
desired access areas, i.e. maintenance and part loading/unloading stations.
These areas have the "MAT" in front of them, and if there are any commands
that take the robot to that cell-station, and you are standing on the
'mat', the machine will stop dead (so you *don't*)! As I indicated in an
earlier post, they also use a 'deadman's switch' (actually, two) on their
pendant programmer that acts as an E-Stop if you ever 'let go' of the
switch. (It takes concentrated effort to hold the switch 'On'). Disclaimer:
I don't own the company... not even any stock.
