As DC42 days the Duet+Duex4 temperature noise issue is only really apparent at room temperature. I picked 1K resistors for the Duet specifically to improve the temp response at printing temperatures (where it matters). In addition the termal mass of the hotend means that the actual temperature is not changing. I will improve the analogue ground in the next version, in the meantime if it is a bother you can use DC42s suggestions
