Hello friends, this affternoon I wired my first CNC Keling kit, 3 stepmotors of 640 oz/ inch, 3 drivers KL-5056, a parallel port board C10 and the power sources. I did it according to the wiring sample that Keling offers for this kind of kit, I checked every connection several times, I have to say that I don’t understand very well the function of the DIP switches which are in the drivers, then I plugged it to my computer and I run a sample in Mach 3 however it didn´t work, I check the essencial set ups for the program, the cable of the parallel port, the set up for the jumpers of the parallel por board, and so on, but nothing, the power indicators are working, drivers and the power source have these lights. In this moment I’m not sure about the possible cause of the failure, I presume:
Altough the program (Mach 3) is running properly it could be generating a bad signal or even no signal, I have only a copy of this program.
My computer (a desk one) and the parallel port board are not generating a significative signal for the C10 board.
Or the C10 has a problem.
I hope you can help me,and if you can, explain me a little more about the DIP swiches that the drivers have, thanks so much for your attention.

The default in Mach3 is Metric measurements. If you are using English measurements make sure that you change it in Mach3 configuration.

The Emergency Stop configuration needs to be set up correctly. If you are not using an emergency Stop switch you may need to install a switch.

The Step and Direction signals from the computer parallel port need to be compliant with TTL 5v logic levels. Check those signal amplitude on the parallel port pins with a digital multimeter.

Check the Step and Direction voltage levels at the motors for compliance with TTL 5vdc logic levels.

Make sure that all motor leads are getting the proper PSU voltage at the motors.

If all of this is correct then there may be a configuration issue in Mach3.
