MZ SKEETER 4,708 Posted May 12, 2021 No mention of what operating system that you are using with your software. Windows updates can change things. You don't state whether the cutter can still do a test cut. Also, unless you are using a Tripp-lite Keyspan adapter with the null modem that came with the vinyl cutter, you probably won't get the cutter to work with a USB to 9 pin connection. A Tripp-lite Keyspan Adapter does work. That is the brand name. And the only USB to serial cable that we advise. Try to see if the cutter will work on a different newer trial software.

MZ SKEETER 4,708 Posted May 12, 2021 Where did you buy the cutter? Did you purchase a Tripp-lite Keyspan Adapter? That is the brand name. Did you purchase this? This works with a vinyl cutter. The MH cutters have a cheap Chinese chipset in them. They are not TRUE USB. Share this post Link to post Share on other sites

MZ SKEETER 4,708 Posted May 12, 2021 Try uninstalling and reinstalling the FTDI driver and make sure it is working. Make sure the com ports match below 1-4. Try new cables. Maybe someone else has something to add. I don't. Share this post Link to post Share on other sites
