Should I change slicer settings first?
Usually no. Confirm bed cleanliness, Z-offset, filament condition, and mechanical setup before chasing slicer settings.
When should I use the Beast Vault path?
Use Hub for free diagnosis first. Beast Vault is the recurring value path for product drops, member support direction, and advanced tools.
