Fell for the cheap price on the VEVOR 53" cutter....Newbe at the craft and didn't want to jump too deep to get started/learn. I am running windows 7, can not get the plotter to cut.....jobs appear to spool to the cutter, never send. If I try to change "port", get a warning "can't change settings. ask administrator".....I am the admin! Cutter comes on normal, set up is standard, and will do a test cut on the cutter/keypad.....Just won't "take" a job from the software. Did read an earlier post and installed the D 720 driver....still noting. US Cutter had nothing to offer...Seller sent me a couple videos.....without any sound?....Not sure what the use in those are. Any help out there??????
