I've got a Liyu SC631 cutter, which has not been used for some while. I came to use it yesterday and it will not print/cut.
I've tried it from Linux and Windows 10, using a direct USB cable, Prolific USB to Serial cable and an FTDI cable. all but the FTDI cable display on the screen of the cutter display ' Cutting .....' and then goes back to the menu, but the head doesn't moved and nothing comes out on the cutter.
Any ideas?
