Marlin firmware fork for MakerFarm i3v w/ auto bed level & Roxy's enhancements

[jtice]

I am in the process of setting up Auto Bed Level and ran into a few issues.
I used this set of videos to help me through the process...

When I went to run the G28 command to home the printer, it now homes near the center of the bed, and not the very back right corner like it used to.
How do i change this back? I am afraid to run the auto level command, cuz I think it will try to go off the bed too far now sense its starting in the middle.

This is probably due to the home position being different in the firmware linked in the first post here.

EDIT
Just went ahead and tried the G29 command to have it run auto level. (still cant figure out how to get home back to 0,0,0)
That seemed to work fine, it took 6 readings and stopped at the last position.
But, if I have the printer start a print, it does not autolevel first.
Is this something that will have to be added to all my gcode?
I see in Cura I can put commands at start and end.
Should I add the G29 command that? Or should I remove the 2 lines that have the G28 command and put G29 there?
I pasted my start code below.
And if I do, I assume it will run autolevel before the print, and store those readings, and proceed to do the print with those readings?

EDIT.......................
OOOOOOOOOOOK, well taking out the 2 G28 lines and adding G29 was baaaaaaaad

Extruder moved RIGHT, hard crashing X and tried to go even further, slipping the belt, had to flip the power switch !!

Should the G29 line have anything after it? Or just G29?

EDIT..........................
Well this is odd, now G29 doesnt even work in Pronterface.
Printer does nothing, Proterface reads...

SENDING:G29
echo:Home X/Y before Z

It also says that if I try to home just Z
X and Y will home seperately just fine.

G28 seems to work, though it homes Z in about the middle of the bed.
The printer moves to the X and Y end stops,
then moves to about the middle of the bed, lowers the probe and end stops it, raises the probe, and stays there.


Now if I try to do a print, and have the original G28 commands in the gcode like before I started all this autolevel stuff,
the printer will home X and Y, then just start printing, without homing Z
It starts to print, and it too low, touching the bed.
So, I am basically stuck at this point and cant print till I get something working right
