z-axis probe won't store [1.1.0 RC7]

I am having a small issue with the autoleveling G29 command. I have a delta printer and added an allen-key z-axis probe. When the G29 is issued, the printer will move to the Z tower and properly deploy the probe. The printer then probes the bed, but when it goes to store the probe after probing, the effector descends until the z-axis probe switches, and then the effector immediately begins moving back up. I have the probe storage position at X=0, Y=-95, Z=-2mm which will properly store the probe, but when G29 attempts to do it, it stops the instant the switch is opened. :/ I then receive an error that the z-probe failed, likely because it is not properly stowed.


These are all the relevant configuration bits, let me know if I missed something. I am using Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN because using Z_MIN_PROBE_ENDSTOP results in the printer not going down to the bed while probing... the printer just moves around and constantly increases Z at each probe point and eventually the effector crashes into the Z tower as it moves to the back of the build platform.

Keeping my configuration values and moving to RCBugFix branch resolved my issue. I suspect that there are some regression issues in RC7, so I filed a bug on github.
