Thread: limit switch- home switch

1. limit switch- home switch

I am using 1842/2900 combo can I set the 3 limit switches to double as home switches? How?

2. Here's my macros to home and park off the limit switches. It saves a buch of time at startup if machine is in park posiiton so i tell operator to do this before shutdown.
