Hello,

I bought the new Hephestos BQ that contains the new Zum Mega 3D board.

Heatbed:
I would like to know how I can install the hot bed, that is, where I connect the cables in the Zum Mega 3D. I think that I need to buy this extension board:

Auto leveling sensor (indutive):
I also wanted to install an inductive sensor, but I also do not know where to connect the cables.

Firmware:
For firmware edited in arduino and then use make to compile?
