@Phaedrux said in Horizontal banding defect, non-kinematic. Need some help!:
Are you not able to control the bed heating loop via the Duet so you can PID tune it?
I have the parts for that in hand, but was holding out with the hope that I could use the off-the-shelf controller for a few months and learn firsthand whether something more sophisticated (like a system with independently controlled quadrants & super well isolated AC) was the better path. Seems like I at least need something of a middle ground to start.
