Re: [CAD_CAM_EDM_DRO] Repeatability of microswitches

It mostly depends on the speed. The system I use on my Bridgeport retrofits
is you go into the switch at one speed and then after it trips, back out
until it clicks again at a slow speed. This seems to give excellent
repeatability with the old Bridgeport limit switches.
