I am trying to connect my 721xe which I had been using with Signcut until the trial subscription expired and now want to change over to Inkscape/Inkcut.
I have spent hours getting the two to run independently but cannot get Inkcut to communicate with the cutter. It returns "com 3 closed by request QsocketNotifier: Invalid socket specified".
I have checked the port is available and not available when Inkcut is run and the port settings match. I have set run as administrator wherever I have seen it advised on the forums and disabled the port power management.
I have tried using the usb-serial ch340 that came with the cutter and MH-712 installed with Inkcut with the same result.
I am probably missing something obvious so apologize as I am now way out of my depth but I would really like to move forward as I want to use it for making 3d low poly art in welded aluminium and some fun stuff for my grandchildren.
Windows 10, Python 3.13, Visual Studio 2022, Inkscape v1.4, Inkcut 2.1.5, Cutter Plotter 721XE
Connection settings USB-serial ch340, baud 9600, byte size 8, parity none, stopbits 1, xon/xoff, language hpgl.
Many thanks Steve
