I use my R3000 rarely and test print it often. While fighting the clogged and air bubbled lines a new approach was suggested by Walker in tech support. First use a plastic cover (I currently use a towel.) and a guitar humidifier to keep things from drying up. Here in AZ it makes perfect sense. These humidifiers appear to be high density sponges in a ventilated plastic holder and run from $6-$20. I just ordered a $13 Amazon unit. Like I said, makes sense!
make sure your nozzles are good first though before the packing
Next door to you, in New Mexico, it’s about as dry. Please tell me how well this works and how often you swap the humidifier or moisten the sponge. Thanks.
