Auto_Bed_Leveling: Z-Probe Repeatability code

[brainscan]

Hi Roxy sorry I havent got back to you for a couple of days but work has been crazy and I needed a rest. I'm just about to try a print with pronterface and your code and thought i'd just add the M48 code first. When I added in the code it wouldnt compile saying #endif without #if at the very end of your code, I tried just removing the #endif line and it compiled and seems to work but don't really know if i've done something stupid. Here are my first results just sending an M48 command
>>>M48
SENDING:M48
M48 Z-Probe Repeatability test. Version 1.85
Mean: -0.167070
Standard Deviation: 0.002544
echo:endstops hit: Z:-0.17

I will have a go at printing something now and see how it goes but when I ran G29 last time this was my result
Bed Level Correction Matrix:
0.999998 0.000000 0.002131
0.000000 0.999999 0.001302
-0.002131 -0.001302 0.999997
isnt the last line supposed to be positive numbers? Or have I got that confused? Thanks again in advance

*Just wanted to try it one more time just to make sure
>>>M48 n10 V4
SENDING:M48 n10 V4
