Agreed on the replication, and since it's not common... As far as I can replicate it - just used Cura on both printers (k280 and Ender3 with Klipper and Octoprint) - didn't lock up for 30 minutes worth of slicing and changing parameters (but avoiding clicking on the "monitor tab" as my normal workflow would... , saving profile, updating them (so I can use the same profile on both printers)... the moment I switched to the Monitor tab and clicked on the side-bar (not on a button), returning to the preview or prepare, the boxes are locked. (as my normal flow, I "preheat" and "home" on the Monitor tab soon after I load the model and start changing my parameters... I will keep on zeroing in on the issue.
