Need Help!- please help getting my first CNC project running

[mioduz]

I am trying to use Mach3 to control a KL-5056D. I am not getting any response from the motor (KL23h2100-50-4B). I am running through a C-10 Breakout board, also using a KL-600-48 Power Supply.

I have +5v delivered to the C10 breakout board to the power and Enable Terminals.
Also have a Wire jumping from Terminal 15 to 5V to simulate an E-Stop Button.
I have wired the Com to PUL+ DIR+ and ENA+
I have wired the PUL- to Port 2
I have wired the DIR- to Port 3
I have wired the ENA-to GND
I made the appropriate settings in MACH 3 motor controls
When I jog controls on Mach 3 the DRO’s change, but the Drive does not Move.
I know I have communication to the C10 Board because I am able to remove the E-Stop jumper wire and Mach3 Responds with an Flashing red Reset for E-Stop.

Do you have the jumper set to connect COM to +5 volts?

Have you set the jumper to make pins 2-9 into outputs?

Can you monitor the voltage between pin 3 and ground, and jog that axis in different directions, and see the voltage change between 5 volts and 0 volts when you change direction?

Do you have a jumper between the External Enable pin and +5 volts?

Thank you for the reply

Yes I have set the Jumper to make COM +5v
Yes I have set the Jumper to make pins 2-9 output
I have the C-10 Board connected to a External 5V Power Supply
I took the following Readings with NO parallel port connection
Both of the Ports (2-3) to ground 3.69 Volts
Com to Ground 5.3V

I will test with the parallel cable connected tomorrow to see if there are any different readings.

One thing to note....I am using an old cable that does not have all the pins. I did verify that pins 1-8 are in place and do connect directly to the same pins on the other end of the cable. Is there any other pins on the cable that need to be present for this to work. This is just a test before I started installing all the steppers. I planned on ordering a new cable for the final install.
Again I confirmed that I am communicating with the C10 board via the EStop does work with Mach3.

Thanks again for the help

ALSO
the drive has dip switches that I have set to:

1 ON
2 ON
3 ON
4 OFF
5 OFF
6 ON
7 ON
8 ON

According to my research this should set the drive for 5.6A peak output power
and 400 Pulses per Revolution.

There is a green light on the Drive.

I have been able to control the stepper via the RS-232 port on the drive using Protuner so I am confident that the motor to drive is connected and the power supply is adequate and correctly wired. Seams to me that my problem exists between the computer and drive.

This should be a key test (with the parallel cable connected), because it should help to indicate whether the axis direction configuration is correct in Mach3.


>>Do you have a jumper between the External Enable pin and +5 volts?

The C10 board's external +5 volt input terminal is different from the External Enable terminal (which must also be connected to +5 volts). Based on the following statement from the C10 manual, my guess is that you do have it connected to +5 volts, otherwise you would not see the 3.69 volt reading from pin 2 or pin 3 to ground:

External Enable Pin (EN). The
board has a pin that allows you to
enable/disable all the outputs at
once. The board requires +5vdc in
the EN pin. If it is not present, it
will send all the outputs to ground.

I will need to double check that (I don't remember which pins supply the ground connection between the PC and the C10 board).

OK, the high-numbered pins carry the ground connection. Does your cable have a shield connected to the DB-25 ground shell at both ends? I'm not sure whether the C10 connector shell is grounded at the board. So that's something that must be checked.

I would also note that the C10 manual states that the LPT port cable must be connected between the PC and the board, otherwise the outputs will be disabled, but I'm not certain which pin(s) it uses to make that determination. So it will be safest if you can do your tests with a full 25-pin straight-through cable.

was there any resolution to this? I am having the same problem as the OP.... Help!

[mioduz]

my situation was resolved by simply getting a new Parallel cable. The one i was using did not use all pins and some of the pins are used for the C10 board to detect connection. If those pins are not present the C10 board will not communicate with PC
