Parallel Port breakout boards, motherboards, and dedicated accessories / Fault circuit PMDX-122

« on: November 09, 2017, 02:23:18 PM »

I have a Mach3 driven FROGMILL with 2 of your 122 boards in series. One of the boards is set up for "e stop" the other "fault". I had a momentary short in the panel (not directly on the boards) and now I can't reset a fault on the mach computer screen. Both the estop and fault green LED's are illuminated, if i disconnect the fault wire nothing changes. Any suggestions? thanks

Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-122 Ethernet smooth stepper install

« on: January 30, 2015, 01:54:05 PM »

I have an existing machine operating under mach 3 with 2 PMDX-122 boards. I'm trying to insert an Ethernet smooth stepper and connect using the 26 pin headers and ribbon cable. I assume I have to translate the pin numbering to match the unconventional numbering of the smooth stepper, is this the case? The machine appears to be wired similar to the "daisy chained example" in figure 11 of the manual. In the example in figure 11 should port 1 of the ESS be connected to board 1  and port 2 to board 2, this seems counter intuitive since the motor pins are  attached to port 1 in Mach  but the hard wiring for the motors is attached to Board 2. Thanks for your help.
