Recently acquired this neat engraving machine with controller and JLS software. Unfortunately it didn't come with/missing the hardware dongle. Pretty much rendering it useless other then being able to control the machines spindle, x, y, and z movements on the AMC controller itself. As for talking to the computer...useless since it's always looking for the dongle in the parallel port. Getting a newer controller from NH is pretty much out of the question since it's still in the thousands of dollars refurbished. Does anyone know how to bypass the software looking for the dongle or should I just tear this thing apart and convert it to MACH or similar?
