People are using nanodlp for top-down too but it will be a bit more difficult to setup. Search the forum, you could see threads about top-down systems.

I just completed my write up of my conversion from top-down to bottom-up.

It's here.

Thanks for sharing.

Which part need to change in Nanodlp's setup page to convert from top-down to bottom-up ?

my print platform will go to bottom when printing finished,this action will kill my LCD srceen(I am using 7' LCD + UV light position-fixed at bottom).

Is there some way to remove the last "go bottom" command in the printing process ?

thanks again.

I just reversed the setting for the direction pin on my stepper. If you can't do that, just swap the coil pairs.

Whatever you do, make sure your end stop is at the TOP of your axis, and just do a good z calibration by using the measure z-axis feature.

You can just flip the motor connector backwards, same G code should work then.
