the yoocnc controlled work if you run the machine slow, most boards it is 50-50 if they will work properly in the first place you can connect an arduino to mach3 it has to be done through modbus.
the cheap chines cnc control boards are all a risk I have seen post where people have brought 3 or 4 of the same board because of the cost quite often they have used up all of them after a year, then they go get a good quality controller and never look back.
cheap will always be a risk.
