What's the secret to making Tormach's passive probe work in PP? I went to setup and selected the Passive option, still no dice. PP tells me the prob has been triggered. It hasn't been. I can even unplug the probe and still PP insists that it's triggered. Sometimes it will go "chug chug chug.......", moving a 10th with each chug but it won't stop even when I manually trigger the probe. Usually it does nothing but give me the silly error msg.
