Wine staves

How do I carve evenly on the outside of a beveled wine stave?

Map the height before you carve.

I would use Bcnc and set the grid to desired pattern and use aluminium tape to touch off from (needs conductor to sense when the bit touches the proper height). Once that is mapped out then send the gcode and cut.

looked at BCNC and the feature is called Autolevel.

also googled and found this tutorial on how to autolevel for uneven surface. he has a probe made but conductive tape would work the same.

while I was using google I also noticed UGS platform has an autolevel feature now.

I would also check this out if you already use UGS platform. seems like it works in a very similar way.
