I was thinking that it certainly has the resolution for it. Just look at the Z axis. If you had a print area of 200x200 mm and 20 drops of water is equal to 1 ml, then that is 0.00125 mm accuracy. People freak out about 0.1 mm Z height accuracy, this is 100 times that. Pretty impressive.

I also had some thoughts on the galvanometer setup. It is a Tangent style galvo. That means that 0 degrees and 90 degrees position of the magnet requires the most amount of energy for a given movement. So it isn't linear, but the software can compensate for this. But, the magnet angle could be placed at a 45 degree angle. And the movement could be roughly 25 degrees each way off that starting position. That puts the galvo in the most sensitive and most linear portion of its range.
