can someone please help on this? beyond frustrated, I finally got the SG90 servos to build the damper fan (the 3d printed one Bryan has on the store) with the delta fan from the kit as well. it's only rotating / working in manual mode. it stays closed in auto or whatever its sitting at when you switch modes. I'm to the point of giving up completely, been stuck on this all day. wound up using the old stoker for the ribs over the holiday because I'm really frustrated with the overshooting and now servo issues. followed the instructions (as best I could) on initial blower & servo setup on the wiki. thanks.
