GRINDING ON MY SATURN AFTER INSTALLING FLEXPLATE

[Emmaslone]

I JUST INSTALLED A FLEXPLATE ON MY SATURN AND WHEN THE FIRST LAYER CAME DOWN IT BUZZED ..I'VE PUT FLEXPLATES ON MY OTHER PRINTERS AND NEVER HAD THIS.  i PUT THE SPACER ON IT AND WAS WONDERING IF THE SPACER WASN'T NEEDED .....  OR SHOULD I JUST RELEVEL IT.  ?
