Tall prints have z banding with chamber heat/cooling

Hey Creality team,
I’ve been printing with my K2 Plus Combo for a couple weeks now and have really enjoyed it. One thing I’m hoping you’ll help all of us users out with is an update to your slicer/machine settings related to chamber heating and cooling. I was excited to finally have an enclosed machine, and especially one that could heat and regulate the chamber temperature. I was disappointed when my first large ABS print ended up looking poorly at the upper layers. I’ve attached a photo of the issue. I tried a tall test tower with the chamber heat turned off, but the cooling set to 40 degrees and got similar results. The second test tower I printed without heat or cooling and it printed properly. Can you please implement better heating and cooling routines? Possibly ramping up the fans and heater slowly when more heating or cooling is required? Hopefully someone at Creality will read this and help us all use this feature properly. Thanks!
