Z Axis Max Movement After Print

[pixelpop]

I had to replace the motherboard in my Saturn and prior to the replacement and required firmware updates, the build plate would rise at the end of a print only as high as necessary for the printed part to clear the vat by about 5 cm. I have lost that ability, so now the build plate rises all the way to the top of the Z axis on each print, regardless of how tall the print is. I can't recall the mod so if anyone knows I would appreciate it.
