The guy who made the robot uses a two thumbs light pressure tamp. I use the weight of the self levelling tamper alone, place, turn, lift about 1cm, drop.
Yeah I've seen Paul's vids on it, I use less pressure than he does. I may try the self levelling one some day, though curiosity is the only driver in this case. What's the pressure that that one puts out?
