I am building my first small gantry mill and would like to understand the relationship between the home switches and the limit switches better.
Is there a standard offset in distance between the home and limit switch positions? What is the typical distance?
Is the purpose of the home switch to tell the machine control program to ramp down the feed rate from a rapid return to home and then move to the home position for that axis?
How do I decide where to position the limit switch in relationship to where the axis will crash?
