I'm cutting out shapes from 3/4" Baltic Birch (with a black laminate on the face) for my sculptures, and getting uneven depth of profile cuts from one side of each piece to the other. The strange thing is that the right side of each piece being cut is cut too shallow, requiring me to manually finish the cuts with a hand held Dremel Tool. The spoilboard has been leveled. The gantry is level to the spoil board. The collet of the router is also level to the spoil board.
If the gantry or spoil board were not level, then I would imagine that all the cuts would gradually get deeper as they moved across the board. If the collet was out of level, then I would imagine that the router bit would cut unevenly all the way around each piece with one edge being shallow and the other edge deep.
I'm using the OOZnest 1500x1500 with a Dewalt 611 router, Whiteside 1/4" spiral up cut bit. I'm using Vectric Cut2D Pro with the following settings:
Board thickness: 0.714
Start depth: 0.025
Total thickness entered: 0.739
Total cut depth entered: 0.739

I've attached a photo so that you can get a better idea of the problem. Any ideas?
