I just purchased a PixMax 14" cutter and control it with Inkscape through the Inkcut plugin. Still playing around with it, but so far no problems. Jobs are sent to the cutter just fine, and I can move the cut head in Inkcuts "control" panel just as well as with the buttons on the cutter itself.
For reference, I'm running Inkscape 0.92 on Linux Mint 19.2 "Tina".
