AccurateCNC PCB after cut/routing, stretched pulley belt

 

 

Hand held video of it doing the cut, guess which part of the cut I forgot to switch on the vacuum for?  Now solved by adding the automatic vacuum switch.

I stretched the rubber pulley belt, so replaced it, at 60,000 RPM it goes wild, I just wish changing our supercharger pulley belts was as easy as this one.
