Re: [CAD_CAM_EDM_DRO] another limitswitch quest...

Jens,
I worked with this type of switch for many years in printers, X-Ray film
changers etc. They are no good if in a dirty environment like Impact
Prnters, Machine tools etc. Watching a printer slam dunk a head into a
end stop is no big deal, but a mill slam dunking a tool into the platten
or work piece is another story. And watching a Highspeed carridge move
at warp 9 (40 meters per second)for 25 meters before hitting the end was
really an awe inspiring thing (AWE S--T)
