Parallel Port breakout boards, motherboards, and dedicated accessories / pmdx 126 estop LED is lit, outputs are enabled

« on: November 05, 2015, 07:54:41 PM »

I had a n/c  estop switch connected to the estop terminals, and it did function....I am not sure what has changed, the estop does not function with mach, the LED is on all the time and the outputs are enabled.

I am not sure what I am missing. I have a jumper on the terminals now.

Parallel Port breakout boards, motherboards, and dedicated accessories / pmdx-126 will only work with hardwired step/dir, not 26pin cable

Hello, I am using the pmdx-126, with ess smooth stepper, and gecko 213v drives... I am not able to get the motors to operate when I am using the 26pin cable plugged into j19, and into the pmdx-133...the step and direction LED's do light when motion is commanded...ie jog. (MACH3)

Before plugging the drives into the pmdx-133, I verified the polarity of the incoming DC (50vdc), and the green LED,did light. I also, checked for continuity on all the pins of the 26 pin cable.

When I wired the signals directly from the terminal strip on the pmdx-126 to the driver terminals, it works just fine.

I am missing something....but can not see it..
