Fyi, I don’t use either spring, the weight of the tube is ok for what I do.

Thanks. I used a tiny amount of pressure on the lower spring - hoping to not need to strip the head down. It's been behaving well on nozzle changes, so fingers crossed!

The final solution was loosening the upper bearing and reseating it, giving the vacuum tube more freedom. I'm now up to 2.2mm backoff, and picking components up & dropping them without resets.
