Take extra care with the FEP film to prevent scratching either side. When not using the FEP film you should lay it on a non-scratch surface such as a paper towel or CLEAN shop towel.

The FEP sheet is pre-cut by SeeMeCNC and therefore has masking to protect the surface. Remove this mask by peeling off from one corner. Do not rush this process, you do not want to create any creases in the FEP film.

After you have removed the masking, lay the FEP film on a paper towel or CLEAN shop towel and use Isopropyl Alcohol to clean the surface of both sides. (Lens cleaning wipes would also work well)
