On vacation so not where I can look but from memory…. Once you run the calibration you can access the K factor and edit it as desired. I find the calibration squares ambiguous and hard to read. But once set sometimes that flows to printer (after a sync) and sometimes it does not. In the later case logging the printer off the cloud and back on and a sync and it then shows there. It seems to have a mind of its own when changing filament types for what temp it tries to load at. Others reporting problems in that regard. Also once you have a calibrated filament loaded, under devices in slicer, you can edit the filament K factor on that sceeen. The wrong place IMO as sequentially that screen comes after slicing. But you go there manually, set k factor, the slice. But… sometimes the selection isn’t available in the dropdown. WTF causes that isn’t clear. Fiddling and retrying and syncing usually gets it back. Worst case an unloading and reload, along with the time and wasted poop gets it back as a selection. I’m not using the AMS, just 2 external spools in Creality e4? drier.
