11 years ago It is easy to specify additional brush positions in the software, but there are a couple of bigger issues.
First, it will be hard to calibrate. Right now, we can say "toggle up/down" to test both positions. For testing three positions, you'll need to be able to compare brush height at the water, and at the paper, or at the paint, or whereever else you need to test it.
Second, there isn't really additional range available with the present carriage design. 20-60 is about the total range available-- if a third value will be added, it will have to be somewhere in the middle, or we need to figure out how to add in additional range.
The wash "cycle" doesn't seem to be aggressive enough to prevent tainting the palette - I'm wondering if there is a way to send a separate brush-up/down amount to the device for a wash. For example if the default up position is 60 and the default down position is 21, then those numbers would apply to pre-dip, re-ink, and plotting, however, for the wash cycle, perhaps use 60 and 10 so that the bristles spread out on the bottom of the petri dish. This should allow for the paint in the brush to be rinsed out more completely at the end of the cycle before going to the next color in the palette.
