What Is Plate Locking in Orca Slicer?

Best Practices for Using Plate Locking

2. Use different plates for different parts of your project. For example, put all small parts on one plate and large parts on another.
3. Name your plates clearly so you know what is on each one.
4. Unlock a plate only when you need to make changes. Lock it again when you are done.

Disabling a plate means it will be skipped during slicing. The models stay on the plate, but they will not be printed.

To lock a plate, right-click and select Lock Plate. To disable a plate, right-click and select Disable Plate or look for a checkmark you can uncheck next to the plate name.
