Domino not cutting parallel to edge

[Spike]

Hi all,
Any help appreciated. Can't post pics without great difficulty but my mortises are greatly out of parallel with the edge. At fist I noticed it in baltic birch. You could clearly see the lamination lines didn't jive with the length of the slot. I tried several cuts on a perfectly prepared piece of dead flat cherry and you could really see the out of parallelism to the edge of the board.

On an 18mm wide mortise it is out .20mm to the edge from one end of 18mm to the other.

Not sure if I explained clearly but thanks. ???

Do you mean the tooling is entering the work at, let's say 10mm from the upper flat surface and cutting the mortise at an angle uphill or downhill, so to speak?  If so, it would mean the drop down "table" of the Domino is out of parallel with the body's flat surface behind the tooling.  I'd send the machine back.

Spike,

I interpreted your description the same as Dixon, and make the same recommendation to send it back.  You could possibly fiddle with it yourself, but why risk voiding the warranty?  My Domino came well aligned.  If it was my machine, I couldn't resist checkin the fence for parallelism to the base.  You should be able to confirm that the fence is out of parallel relative to the base by stacking a couple of thicknesses of the ~3/4" birch plywood on top of your MFT (or other known flat surface), raising the Domino fence, setting the Domino so its base is resting flat against the top surface of the MFT, then slowly lowering the Domino fence until it contacts the top surface of your stacked workpiece.  If you use only one thickness of the plywood, the fence likely will not lower enough to contact the top if your workpiece due to it being thinner than the minimum setting of the Domino fence.  If your Domino fence is out of parallel to the base by the amount you described, it should be easily seen during this self-test, with one side edge of the Domino fence touching the top of your stacked pieces of plywood while the opposite side edge of the Domino is above the top of the stacked pieces of plywood.

Precisely guys, that is what is happening. Wished I could post a picture. I don't want it repaired, in fact I don't think it is repairable unless a simple change out of the fence system takes care of it.
