Just had a crazy thing happen to me. The scanning probe would pierce my sled and bend the tip. This is only the second time using this probe and it worked fine last time. Everytime I reset the scan area it would do the same thing. I tried adjusting the depth and the offset with no change. I found that my machine will take both the jumper wire and Z truck plug. I was using the jumper when all this happened. Using the key pad I switched to the Z-truck setting and all is fine. I hope this helps anyone else with the same problem and saves them the 2 hours it took me.
