Auto Bed Levelling Glitches

[Roxy]

I'm running Dacb's firmware mod as at the time it had everything I needed in there, and pretty much configured already for me. I've included my Marlin_main.cpp as well

I looked at the Marlin_main.cpp vs. my Marlin_main.cpp. I have some questions about the sled docking but I think that is OK. I'll know more in a bit.
Did you run the Post Processing GCode script to limit the size of the probed area?

Are you giving it the G28 and G29 commands via the keyboard? Or are they coming from a GCode file? It would be helpful to see the GCode file you are trying to print also.
