Usually Linux will see and use the usb chip set used in your cutter just fine and the new eg:“/dev/ttyUSB0” port will appear when adding your cutter as a cups printer.
However with inexpensive cutters using inferior or counterfeit chip sets Linux may have an issue to be resolved before it can be used properly by Tux Plot.
In addition a work-flow demonstration of a sample plot can be useful for some users. The Tux Plot YouTube videos do show most aspects of creating and plotting a plot job but if needed this remote help is available.
A standard $50/us fee is payable via paypal for a remote one hour session.
Note: If free time is available once problem is corrected I can finish the hour up with improving your desktop with extra tweaks and features.
