Z probe state not being read with 0.92.3 on Sanguinololu
I am trying to set up my Delta printer and I am having trouble with the Z-probe state. I first tried firmware version 0.91 and I got the printer was working. Z-probe state is read as L or H as appropriate. I followed the instructions here http://www.repetier.com/documentation/repetier-firmware/z-probing/ to set up the bed levelling (I wanted to test a stable version first). The instructions explain that you need version 0.92.X because of bugs in the auto levelling code.
After I was confident that my printer was working I wanted to try the distortion compensation, so I downloaded firmware version 0.92.3. The configuration files match, except for new values. When I use G31 with 0.92.3 the printer returns "Z-probe state:" with no status.
I have tried comparing source files to see if there was a simple error, but as I'm not familiar with the Repetier firmware source code and there are a lot of changes between 0.91 and 0.92.X my investigation was much in vein.
My set up is as follows:
- Repetier 0.92.3 on a Sanguinololu with ATMega1284P.
- Repetier host 1.0.6
- Z probe pin is 16
Here is some log output to show the difference in the two firmware versions tested.

I'd be happy to provide any more information necessary.
