#3DPrinting experts: on a textured PEI sheet, should I still be using a separation layer (like glue) for PC? I've done a few prints on bare PEI, and it's starting to mar the texture and change its colour, though not severely.
Note: this is _not_ a question of adhesion or warp prevention. My Z-offset is correct (and going higher didn't prevent this marring anyway), and adhesion hasn't been an issue.
