I just started using my domino joiner, when I work with 1/2" thick wood, it will not center its cut.  I have to place the board on 1/4 plywood to get it to center.  Is this normal?  does the domino cutter only work on boards 3/4 or thicker?  Chalky
 
For 1/2" material, you need to put the 1/2" board on another board to elevate it enough for the tool.  From the bottom plate of the Domino to the center of the cutter is 10mm and you're needing basically 6mm from the bottom of the board to the center of the mortise so you need a 4mm shim.

You must have a newer Domino than the first run with the metal pins.  That model (my model) was unable to set the 90* fence to 6mm as there was some metal in the way for the fence to drop 90* at that offset.  If you are 'compensating' by setting the fence to 7mm or more (and having an off-center mortise), watch what the fence hits when you pivot down 90* and file it away.  That was a fine day for me as I was working on a project based on 12mm ply.
 
Shims for using the Domino -- If you are in need of elevating material by some small amount or offsetting the Domino by a small increment, the Domino's 3 best friends are:
(1) thin MDF (such as 1/4")
(2) a Performax thickness sander (or equivalent)
(3) thin double-stick carpet tape

Build an inventory of 1/16, 1/8, etc strips and pieces.  Also make some strips and pieces in metric units such a 2, 3 and 4 mm.  Work out of this supply, don't live hand-to-mouth or you will kill all kinds of time.  If you do not have one of the thickness sanders, find a fellow woodworker who does and have them do it for you.  Two tips: (1) have adequate dust collection and dust masks  (2)  you do not need fine sandpaper, medium will be great.

Just tack the pieces of mdf in place with the double stick tape to support/align the Domino in a wide variety of configurations

The above technique is great when working with the 4mm Domino bit with 1/2" material.
