Domino, how do I get the cut centered

When I set boardthickness gauge at for example 18mm, the cut isn?t centered in the workpiece. Does the machine need calibration?
Is this a common problem?

Thanks!

Patrik,

Welcome to the forum, always good to have new members!

Regarding your question, you can use the search feature on the forum and will find several other threads about this topic.  Generally, there is no real requirement that the mortise is in the center of the material as long as you reference off the same side of both pieces.  There is a gauge on the back of the fence which can be used to set the fence height based on the material thickness to help if centering is desired.

I would highly recommend the following PDF documents from our website which offer a lot of tips, tricks and useful information about the Domino and speak about vertical centering techniques.

I use the edge of the two guides on each side of the domino.  If you mark the center of the workpiece, you can align that guide to the center mark and you'll be very close to the center of the board.  It's also a very handy way of aligning a mortise to a particular place on a leg or other piece where indexing from the edge may not work accurately.

See the photo below from one of the manuals that Shane provided.  I index to the orange line where the two guides are.  That line is the center of the mortise cut by the Domino.

Good luck -

It doesn't have to be perfectly centered in the workpiece, especially if your working with sheet goods.  I thought it had to be centered as well when I first got my Domino, but I quickly learned to work with the settings instead of against them.  For typical 3/4" (18mm) plywood, I use the 19mm depth stop setting.  Using the depth stops allows your work to be repeatable and accurate, where sighting the depth scale will not.  Just pay attention to the reference faces of your work, and don't worry about centering the tenon exactly.
