I am very new to the Mach 3 software as well with my machine. I purchased a CNC 3040 machine and I downloaded mach3 to run it as the manual suggested. I followed the instructions in the manual to set up the ports and pins. I installed an after market parallel port in my PC. I found the address for this port and entered these addresses into the port setup and Axis selection. At that point I was able to jog all the axis, not very smoothly but they did move. I haven't changed any settings but now I can not get anything to jog.
Like I said earlier I am a newby and I am probable missing something easy. If anyHone. An help I would be greatly appreciated.
