I see the first paragraph of my last post wasn't clear. Here it is again, hopefully more understandable.
For homing, could you give the PID command a constant ramp (use the integ component?) until the "home" microswitch closes. At that point, save the feedback encoder's position as a constant offset (sample_hold component). For operation, feed the sum the stored offset and the desired tool position to the PID command to go to the desired tool. I think you could (should) still use the limit3 component right in front of the PID command input.
