Both show good in the Tek 'scope with the probes clipped onto the little bit of wire accessible from the screw terminals on the 7i76. Hard to imagine the wire clamped in the screw terminal but not making contact. With LinuxCNC running doesn't it reset that count with each read so it only will show the counts since the last read?
