I see your point (no pun intended), but many modern keyboards require very little pressure to press a key. I can just use a pen heavy enough to press a key but light enough to be lifted by the Axidraw vertical servo. I just did a test with some quarters, and 1.5 ounces worth of quarters depresses a key gently. I suspect that the Axidraw can handle a pen weighing 1.5 ounces. I don’t see the maximum weight in the Axidraw specs. Can you tell me if it can handle a pen weighing, say, 2 ounces?
