2-bolt seatpost adjust
 
I have a question on adjustment of a 2-bolt microadjust seatpost. It is a Sette APX though I've seen an identical one made by Kalloy. Anyways as I gather the balance between the two bolts sets the nose angle. However, to get it level the bolt in front is sticking far up into the cutout of my saddle and the rear is barely fully engages in the threads of the hinge. Did I do something wrong?

Is it rotated the right way? Spin the post 180 degrees and see how it looks.

Don't mean to be insulting, but did you install the seatpost so that the setback is in the back? Sticking it forward screws up the angle.

It may be that the angle of the saddle rails relative to the saddle (in a flat position) is a bit wacky, at least for your seatpost.

Edit: Also, are the two bolts the same length? If not, would switching them help?

It has no setback and no indication that it should face a certain direction. It has a name stamp on both sides of the post so no matter which direction you face forward it looks the same. It has two bolts one in front and one in the back.

I have a generic version of that seatpost. I thought I would be getting the single bolt version from Dan's comp.
I'm guessing the front should be where the seatpost dia. and min insertion markings would be.
yeah, my rear bolt digs into my saddle too if I compress really hard on that area.
I don't think you're doing anything wrong.

That does look symmetrical, but I'd try turning it around anyway and seeing if it helps, in case there is a difference that is not so easily seen.

Otherwise, you can't really do it wrong. If the rear bolt is fully engaged, it's fine, or you can get a slightly longer one. The front one can either be cut or you can find a shorter replacement one (I'd do this and keep the original) if it gets in the way.

As I said before, the angle of the rails relative to the rest of the saddle vary from saddle to saddle, and this saddle may just be pushing the limits of your seatpost (with original parts).
