Sacrificial plate

When I got my A350 and used the CNC module for the first time, I made a sacrificial plate out of a piece of POM that was still lying around with me. At the weekend I milled grooves on my Snapmaker to make a vacuum plate out of them. Drawn in fusion. By installing the sacrificial plate, I was able to reduce the evenness of my bed from 0-0.4 to 0-0.05mm. I chose Pom as a sacrificial plate to be able to pull off the strongly adhesive tape without leaving any residue.
