The way the LS IHS works is that it goes down at 100 IPM until the switch opens and then reverses direction at 20 IPM until the switch closes again. It records the Z zero at the point where the switch closes again.

Ah, I missed that. Thanks for explaining! Yes, that should be very close to zero in every case, I wonder why they continue to keep the backlash in the post processor.
It’s interesting that that method wouldn’t work if they used traditional limit switches because those typically have hysteresis built in. With the bent tab it does.

I can confirm that the Fusion post adds an additional .02" to the springback value. (i.e. - If you enter .02", the post adds .04" when establishing Z 0.) In the post they refer to the second .02" as backlash.
