Overscan Doesn't Work Build 1589

I'm trying to adjust my projection but I tryed diferent values in config.txt but nothing seens to work.

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
# disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
overscan_left=1000
overscan_right=1000
overscan_top=1000
overscan_bottom=3000

Overscan could not be nanodlp related.
Could you share photo of boundary image being displayed on your printer?

It's possible to have a feature in nanodlp to choose where you can put the origen from X and Y, mine is X-4 Y0 I guess

Use center origin. you can put pieces wherever you want on your 3D editor.

But my projector center isn't in the center and in this way i have to use another software to "centralize" it
