X is the twin ballscrew axis here.

I think that's the most likely cause. Was going to mention it yesterday...Since the centre of the tool is moving at a much lower speed than the outside it will not cut as well, as is the case with a ballnose cutter. If you move further out the speed is greater, and more consistent so it will cut efficiently with a sensible spindle speed and lower force, therefore lower deflection.
If you're using a 90° tool then it's easy to work out. If the depth is equal to the offset then the tool is at zero. For instance if you add an offset of 3mm (using the allowance box in V-carve, or just select a 6mm cutter) and start at Z=-3 then the tool is at zero, so cutting down to Z=-5 will get a 2mm chamfer. In reality it's easiest to use this as a starting point and just lower the Z-axis until the chamfer looks nice as that generally matter more than the absolute value!
Be wary of what the other side of the V-cutter is doing as clearly with too great an offset and nested parts you may end up cutting adjacent parts too much.

What cutter did you use for the chamfer? I just use a standard 90° 1/2" router bit.
