Does anyone here have a vevor 3020 router machine? I bought one and it showed up a few days ago, I downloaded mach3 a few weeks before I ordered the machine to see if I was able to figure out how to use the program. I set the parameters according to the mach3 instructions, but imunable to get the machine motors to respond in any way. The dro move accordingly,  the machine uses a USB output not a parallel port. I've read that mach3 goes into simulate mode and I need to get it out of that mode, but I don't know how. Does anyone have any experience with this?
