Woah, tell me it’s not the long one that faces the coffee? The top one shouldn’t be a problem as it’s similar to an espresso machine screw. It’s generally better to dose so the puck doesn’t swell against the screen anyway, as it’s thought to cause channeling.
No the short one faces the coffee. The way the robot is set up is you tamp your coffee into the basket, then place this screen on top. The long one is to help you grab and place it. This means the screen always touches the puck.
