Troubleshooting...

There are a few possibilities.

A ) The small ribbon cable running down to the Z-truck
B ) The small circuit board in the Z-truck was damaged when the sensor broke
C ) The probe itself has an intermittent contact
D ) The board sensor wiring is pinched, this is unlikely as you would see symptoms while carving too.

I'm thinking A or B. I removed the probe from the quick change and shook it around a little bit while reading the probe sensor, and it stayed closed, same with flexing the wire from the probe.

Is there any way to get at the circuit board without removing the Z-truck? I'm a bit apprehensive about doing that, since I've heard told on this board that that taking apart the Z-truck is a bad thing, especially since I'm on warranty. I think I can get at the ribbon cable, so I'll try that, but I think the little board might be a send the machine back home type of repair.
