Title: auto tool zero with limit switch
Post by: Programinator on June 28, 2015, 07:50:53 AM
my machine came with 5 switches and i am only using 3.  I have seen many people setup a touch plate with wire and ground.  i was wondering if it was possible to just use one of the limit switches for this purpose.  Rig up the switch with a plate on top and set it under the tool and run the auto tool zero script.  Wont that work?

I doubt very accurately. There has to be a couple thou variation in the switch especially if the speed varies.

IF using the G31 call to find the plate/switch speed has NOTHING to do with it. HomingG28.1 yes,  probingG31 no. It is best to use a simple contact switch not a snap switch.
