Since the virtual COM ports show up in the Device Manager, your software should also be able to find them. All you have to do is add all available ports to a combo box and let the user select which one to use. The Black Widow is based on the MKS 1.3 - 1.4 board, which is Arduino based. I will send a message to Tevo to see if they will work with you.

Cura 2.4 can't connect to my Tevo Black Widow on COM26. Cura 15.04.6 does easily. I know this issue keeps coming up, but is there a workaround available or should I uninstall 2.4?

I have a Tevo Black Widow printer.

Is there a way to tell Cura what to do if I cancel a print? I'm using 15.0406 and if I cancel a print, the head just sits there in contact with the failed print. I want it to raise the extruder at the very least.
