Could you post a picture of what you have on the top?

No the nut that is controlling the height of the z bed. The newer printers have a different nut from what I seen in pictures.

I see the new machines have a different z nut that is on the threaded shaft. Does anyone know the part number for this and is it a bolt on part?

#define Y_ENABLE_PIN 25

This is what i'm seeing. I'm using the stock firmware for a silver z motor with a viki 1 lcd running 24v ps and and 40w heater.
