Automatic "Bed Leveling" (ABL) With the CF6.1 Refactored Firmware

Perhaps the most iconic of the CF6.1 User Interface screens is the "View Bed Mesh" screen. Some Facebook and Discord members love to post pictures of "all-green" bed meshes, while others solicit advice on how to "get to green", from puzzling rainbow-coloured displays. This "short" video is devoted to walking CF6.1 users through the features and functions of the ABL Calibration screens. A second (likely much longer) video will follow close behind this one, with a more detailed explanation of the components and operating principles of the "nozzle as probe" ABL system which defined and distinguished the CR6 printer when it was first launched on Kickstarter. Failure modes, recommended mitigations and all discussions of rainbows have been reserved for that second video, to help keep this one "short". NOTE: The initial release of this video included a section on Z Offset, which I have since removed, to revise and republish as a separate tutorial, just prior to this one in the playlist.
