The fix for IHS sticking and causing slow probing cycles or high (in the air) pierces is to add a software debounce to the IHS cycle. We have implemented this in a firmware update to the Motion Control Board and new versions of the two Post Processors.
To update to the latest Version of the Machine Firmware, please use FireControl Version 20.5 or later and select the Update Machine Firmware option from the Help menu.
The associated Post Processors can be downloaded from the Langmuir Systems Downloads page.
