Just received my eBay 3040 CNC machine today. Wanted to try a cheap one to see how I like it before I move up to a larger one. Bought this machine:

4AXIS 3040 CNC Router Engraver Engraving Drilling Milling Machine USB 3D Cutter | eBay

Now I have it out of the box and up on my table. There was no software or drivers for it in the box. I've contacted the seller about that. But don't know what to do now. Any free software out there to try? What do I do now?

Thanks in advance!
