Unless I am understanding this wrong, I figured an axis
would travel there and when it hits it thinks "I am home" ?
There are a couple things you have to do to the .INI file
tomake a shared home/limit work. First, you have to set
HOME_IGNORE_LIMITS = YES in each axis section. Then, you
have to set the HOME_OFFSET to a value that makes the axis
back away from the switch enough so that it is not tripped
when it gets to the offset position. This allows the axis
to ignore the limit switch DURING the home sequence, and
leave the axis such that the switch is not tripped when it
arrives at the home position.
Once the axis is homed, you can then jog around manually and
observe the machine coordinates when at the extent you want
to set as the soft limit range, and enter these values into
the .INI file for
MIN_LIMIT and MAX_LIMIT to set your desired soft limits.
