Cause: Z reset position (FEP)/ peel force.

Solution:

1. Z reset position: for FEP we can have a range from 1816-1820. Try with each value from low to high (using the test ring) to find the value that works best (sometimes it can go to 1822).
2. Peel force: Peel force involves PM reset position, hollow and vent holes, support cluster. Reduce the value or go back to default settings. Vent holes should be 3mm.

Cause: laser power/ PM reset position (FEP)/ peel force

Solution:

1. Laser power: make sure to follow the spreadsheets: https://docs.google.com/spreadsheets/d/1t8bjlfk7irSJFy3kzOr-I6SN5acE8UIlOl2E4r3dG_8/edit#gid=0
2. PM reset position: on FEP when the PM reset position value is too low, it would cause unclean peel motion and that would affect the whole print.
3. Peel force: this is the same with print sticking to vat
