Yowana has been posting about her pnc issues on Facebook. It seems that there are issues with pnc with her new Cameo (even with Sil Studio) and I have suggested that she contact SIl America. For what it's worth, I've personally never had an issue pnc-ing with MTC although I understand that there are many possibilities to why a pnc with MTC and the Cameo can go wrong. Sometimes it is the error with the paper placement and at other times it is because the design has gotten outside of the Cameo's pnc zone. Then again there are times when it could be a machine error. Without more information and screenshots, sometimes it is really hard to pinpoint where the error is.
