Auto_Bed_Leveling with positive Z_PROBE_OFFSET_FROM_EXTRUDER

[Roxy]

The problem is his Z_PROBE_OFFSET is positive. The firmware doesn't expect the case where you drive the nozzle into the bed to take a measurement. So we need to make a few tweaks to the firmware! I can hardly wait!!!

OK, I have downloaded the latest version of Marlin and prepared it as I think is correct for my machine.
When I go to compile it I get an error.
Maybe I did something wrong in the pins.h

Tell you what... I've attached my Pins.h I have my Y-Axis limit switch on the E-Limit switch. So, you can either move your connector to the same spot on your PrintrBoard, or you can change the pin numbers back for the Y-Limit switch. (The reason is there is a conflict with the SD-Memory card pins. Moving to the E-Limit switch resolves the issue)

Specifically... I have my Y_STOP_PIN set as 37. You would change this line to be like this if you don't want to move the connector to the E-Limit location:

#define Y_STOP_PIN 8


That should get us past the compile issue.... However... The strange thing is I don't think you need to mess with the Pins.h file typically. I had to edit some stuff in there to get my servo pins defined. But you aren't going to have a servo, so it seems strange that Pins.h had to be modified from its original state.

I also have my Y on the E stop and my Y_STOP_PIN set as 37
I changed the pins.h just in case I stuffed up somewhere else, however I am still getting the same error message.
