I'm skeptical that it's the extruder as it doesn't even look like it moved during either click.

have you calibrated each motor after you changed the board?
Is it actually extruding? Sounds like it might be slipping / grinding. Is your hot end plugged? Can you push filament through manually?
Edit: never mind, watched it again and can see the filament moving. I'm with the other guy on this, is it even your extruder?
