Software update

I updated the software and now my rotary attachment is not working properly.
It was all calibrated great and now it is all off.
If I engage the rotary attachment it rotates 36 mm, no more.
If i turn it off it rotates all the way.
on, 20mm square is x=20mm and y=3mm
off, 20mm square is x=20mm and y-40mm

PLEASE HELP
