1.1.0RC7 & BLTouch

Anyone else tried to build RC7 with a BlTouch probe? Built-in support for the BLTouch was added in RC7 and it seems that all you need to do is uncomment the line //#define BLTOUCH at line 456 in configuration.h.
However, if you do this the compile fails with "STOW_Z_SERVO' was not declared in this scope"

I'm trying this with a virgin configuration.h file with only the #define BLTOUCH line edited. I wanted to see if it would build before editing all my other config changes.

Worked for me.

// The BLTouch probe emulates a servo probe.
#define BLTOUCH

// Z Servo Probe, such as an endstop switch on a rotating arm.
#define Z_ENDSTOP_SERVO_NR 0
#define Z_SERVO_ANGLES {10,90} // Z Servo Deploy and Stow angles

Only lines I uncommented besides this one:
#define NUM_SERVOS 3 // Servo index starts with 0 for M280 command

Got it working myself a few days ago and forgot to come back to mark the topic solved. It was another editing error in configuration.h. When I enabled the new BLTouch define I didn't realize at the time that I needed to also update the #define NUM_SERVOS. Once I set the number of servos to >0 all went well.

Also, with BLTOUCH defined the following lines are not necessary.
#define Z_ENDSTOP_SERVO_NR 0
#define Z_SERVO_ANGLES {10,90} // Z Servo Deploy and Stow angles

They are set in Conditionals_post.h if BLTOUCH is defined.

I'm still having an issue. Everything is working as expected. G28 and G29 work fine. However, after the G29 the nozzle is not dropping down far enough to print. I made a great print last night with

#define Z_PROBE_OFFSET_FROM_EXTRUDER -1.73, Now today I'm at #define Z_PROBE_OFFSET_FROM_EXTRUDER -1.90 and its still not far enough. I ended up giving up and just eliminated giving the G29. My beds actually pretty level so I can get by with just a G28 for now. Seems a waste though since everything I did to upgrade software was to use the BL Touch. Pretty frustrating. Any ideas?

Thanks

Did you do a M502 and M500 to lock in the new settings to EEPROM? Do you have a z_offset defined? (Check the numbers at the end of the reset/power up dialog)

Yeah I update with each change and it shows on RH after reset or power up. First thing I watch for. No z_offset defined.
