Justin,
In the Motor Outputs tab, the "Dir Low Active" should be checked green. I'll check for other things. Greg |

Havn't checked your Mach screens because I am rusty on that, but the following may help . . . .
Have you moved jumper JP1 on the PMDX to the lower GND side for the G203's? Are any green LED's changing on the PMDX when you try and make the motors go forwards and backwards? (The LEDs nearest the DIR pins. ie pin2 on J1) should be "on" for one direction only). The STEP LED will blink too fast to see with the eye. |

Have you checked to see that your port address is correct?
Mach defaults to 0x378 but that is not always correct. Check it in device manager. If not sure what that is then watch the Mach setup videos. Greg |

Have you checked to make sure all of your wires have continuity. You can touch the heads of the terminal screws at both ends of the wires with the probes of a multi-meter. I usually set the dial so that it beeps when I have continuity.

Motor turns with different computer
We made the suggested changes (THANKS GUYS) but still no movement. So we installed mach on different computer and were able to get the motor to turn in one direction very slowly. My guess is that the printer port on the first computer is not strong enough. Can't wait to hook up the big power!

Video of one motor turning.
Check out the smoothness of the motor, can't get over it. Most of our problems in getting the motor to turn came from not having the jumper pins on the PMDX 122 in the right spot. Remember, there are more than just 1.

My mistake was only moving JP1 down and not moving any of the other pins. We now have it just like your post. Did any one watch the Video? |
