Start with min hole size at 1 mm and max around 4.
Melamine faced chip board and laminated mdf work good.

I have never timed but I would estimate that one of those doors ( from the tree cabinet) took around 1 to 1 and a half hours. Those doors were 15 thousand holes each. Probably could go faster but as you say you don't want the z axis losing steps as it works very hard and would be a bugger to reset.

Melamine faced chip board is a good idea. I can't remember where I saw it now but after cutting this guy covered the board with black dye. The dye stained all of the cut sections but wiped clean from the melamine leaving a very high contrast design.

15,000 holes for each door! Wow! So that's a minimum of 30,000 z movements? 60,000 for both doors.... Amazing.

I wonder what kind of strain that puts on the z screw?
