I installed the Mach3 software to a new computer with brand new ports. I was able to get the machine to function but it seems the Z axis and the A axis are not running. I am wondering if this is due to the Step/Dir issues for the output or if I should be checking the machine iteself. Is there a way to test each axis to make sure they are working correctly? The machine will go to the home position but that seems to be the only action I can see working properly.
