Hello, this is my first post here; hope I'm doing it right.I have a HY-6040 5-axis machine (but only using 3 while I get my head around this CNC stuff).When the machine first arrived I could move in all 3 axes using the blue keypad device.Sometime later the axes would not move!Later still I hooked the machine up to Mach3.Still no luck getting the motors to turn.I have spent several days checking and re-checking and still no luck.Has anybody got any ideas about this problem?Thanks in anticipation,Rob JuppAustralia
