Does anyone out there use FDC Vinyl? My router is not cutting through FDC paint mask clean anymore (bit is sharp). It really roughs it up. Also, I am having to use 2 times the downforce to cut with plotter on all FDC vinyls as well as the paint mask (just replaced Teflon cutting strip). Just wanted to see if anyone is having a similar issue. Any thoughts are much appreciated.... Over, Sarah
