The other day I was starting a scan when the machine head attempted to spin with my probe mounted in it and hooked up properly to the connector on the left side of the inner wall of the machine. What it did was spin the cable to the back side and attempt to go down to sense the material. When this occurred the cable connection to the probe head was damaged. Being fairly handy with electrical, I repaired the connection and continued with my scan succsessfully. Has anyone else had this happen?
