Z banding is a frustrating artefact that can ruin 3D printer quality. Even worse, it can be very hard to pin down the root cause and apply a fix. Two of my patrons, Derek and Patrick, have designed well considered potential solutions for Z banding. In this video, I try them out on two of my machines.
Although these specific fixes didn’t improve the print quality of my printers, that doesn’t mean they won’t be suitable for yours. I like the design for each and how they aim to address Z axis problems.
