Pierce height is set via the AUTO F/S settings, or manually with M207. Follow the steps below for troubleshooting regarding the torch piercing too high.
Reset trigger depth
Reason: Torch touch trigger depth set incorrectly
Torch touch trigger depth is the difference between the Z location where the torch touches the material and the Z location where the touch switch in the floating Z head registers a touch-off.

Reason: Wrong material picked in Auto F/S or M207 not set
If using M200 Auto F/S, ensure that you have selected the correct material on the Main tab of PathPilot.
Using the M200 Auto F/S system chooses a pierce height appropriate for the selected material.
If not using M200 Auto F/S to set pierce height automatically, make sure that you have a call to M207 in your program to explicitly set a pierce height.
