I've been using the touchplate widget for about 6 weeks. At first it worked great. My touchplate is 15.1 mm tall. The widget returns to the height + 2mm, so it should normally returnto 17.1mm. Recently it only works about 10% of the time. All other times, the returned z-axis height is pretty random. I've looked over in the Chilippeppr google page without finding any help. When the touchplate works, it saves lots of time not having to return the work piece's origin. Does any one have any suggestions/fixes/workarounds?
