I think I have this Anycubic Kobra 3 Max Combo with the two ACE Pro units finally mastered, along with the Slicer Next software. I've run off around 14 football club logo designs so far with excellent results. My filament breakage problem appears to have been caused by a piece of the self-printed resin hub snapping off and dropping into the print head. I printed another and replaced it while I still wait on the official hub to arrive from Anycubic. So far, I'm really impressed with this machine.
