Dakotagrafx 7,297 Posted December 8, 2015 YES - proven many times over - static builds in the vinyl and stand then discharges thru the cutting head and fries the board Share this post Link to post Share on other sites
TLC vinyl signs 0 Posted December 8, 2015 Ok sweeet thank you very much. And where abouts do you ground it from and to.. The power supply has a spot for a grounding wire would it be from there to a screw on the stand? Share this post Link to post Share on other sites
Dakotagrafx 7,297 Posted December 8, 2015 you need a bare metal spot on the stand to a good ground on the cutter - problem with the mh is the stand is insulated from the cutter (which is grounded thru the plug) so the stand and vinyl make a pretty good capacitor Share this post Link to post Share on other sites
