How close to the physical end of travel should a limit stop switch be placed? They will be adjustable but I'd like to get in the ballpark. My machine will have a top speed of around 200 inches per minute. I'm planning to install six switches, two per axis. The limit switches on one end will also function as home switches as is possible using Mach 3. I know I could use soft limits for the other end but I just feel better about having limit switches at both ends of travel.
