Holding the Z-axis height after printing

Hey,

I use a webcam on the UM 2 Extended + that’s mounted on the building platform (not heated!).
After finishing a print the platform will go down to zero but that would crash the camera mounting.

Now the question:
Is the platform driven downwards by the electric motor or just by gravitation, because then it would be possible to put something under the platform to stop it and hold it a little bit over zero.

Thanks for your help!

Greez,
Andi
