I bought an used but functional Hot Wire CNC with this board usb6560axis4.
I updated the firmware and now I can't activate the license of USBCNC.

I want know if you know other software freeware or opensource for this board like openbuilds, or if is better buy another board controller.

I only want the controller software for cutting. I already have the genuine Devfoam Pro to draw the GCode.

Thank you
