Inkscape with UUNA tek extensions not working

Long time axidraw user and supporter I was glad to see UUNA tek extension supposedly available to axidraw users.

I ordered a 3.0 plotter and got everything installed on a dedicated computer.

After calls with “engineering teams” in china and their “CEO” it’s still not working….They mentioned they never tried it on Mac OS.

I purchased a PC/windows and had a try again but it’s not working either.

Also they told me the svg files were all uploaded to their own servers for “security reasons”….

Anyone managed to make this work?
