Auto_Bed_Leveling: Z-Probe Repeatability code

[Trike]

I'll give it a try. I'm just using a cheap kw12 switch and a hitec HS65HB servo. This is my first printer (prusa i3 rework), so i'm still dialing it in and getting a feel for it. The bed is con-vexed in the center once it warms up. I was getting pretty inconsistent prints. Once I enabled auto bed leveling and used 25 probe points, everything magically started printing good.

I like your code, it'll at least give me a baseline to work off of to see if the switch might be failing.

A lot of people want to use a 3x3 grid. Probably because in the Configuration.h file it says there shouldn't be a need to go higher than that. But I know 4x4 works much better than 3x3 and 5x5 works a little bit better than 4x4.

How do you know there is a high spot in the center of your bed? (I'm guessing that is what you meant by 'convexed') Did you see that with the T option on the G29 with a 5x5 grid?
