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

Thanks for all your help Bob. Everything is up and running better than ever. The 4th axis problem turned out to be a piece of Styrofoam jammed between 2 signal pins. If any one has an older FROGMILL by streamline that came with Mach 3 and they want to upgrade I would be happy to share information.

Thanks Bob, I  swapped the ribbon cables around for the 4th time and this time it worked for some reason, so I have XYZ motion. unfortunately no A axis and judging by the flashing lights on the controller I think it's a controller issue. It was powered up for awhile without a motor attached and although the manufacturer said it wouldn't hurt it I'm not sure what else it would have been. Anyway thanks for your help.

Thanks Bob, Yes your right that does show encoders I didn't look closely enough. this machine has the motors connected to board 2.
Keep in mind this machine has worked for a number of years and this is just a smooth stepper installation. Nothing has been changed on the boards.
Jumpers are set as follows;
Board 1
JP1 Grd&com
JP2 always & pin2-9 enable
JP3 not estop & outputs enabled
JP4 normal -pin17 out
JP5  out & dir
JP6 Estop signal only

Board 2
JP1 Grd pin 2-9 com
JP2 OK- 2-9 enable
JP3 CP OK& not estop fault- output enable
JP4 OK & pin17 out
JP5 out & Dir
JP6 normal- estop mode

3) the motors are connected to board 2
4) the ribbon cables have bumps. if you lay them flat on a desk the bumps are both facing the same side. I made the ribbon cables.
5) Outputs enabled led does not light (either board) e stop light is on board 1
6) motors are assigned to port 1 in mach
7)no inputs or outputs work
8)nothing moves

Any suggestions for me to try and get motion back? If the machine was working before the ESS and the ESS is talking to the compter any suggetions what to check. thanks

The port 2 pins 2-9 are set up in the ESS General Config as "in"

I'm connecting the 26 pin on the ESS to 26 pin on the PMDX 122 J9 connector using port 1 and 2 and 2 PMDX boards

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.
