Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-134 Axis #3 doesn't work
« on: September 21, 2015, 06:22:20 PM »
Last year when I was first putting together my control box I assembled my PMDX-126, PMDX-107, and PMDX-134 as described in the documentation. However, one axis had no output. The other three worked fine. I wasn't sure if I had some how done something wrong. So I removed the 134 and wired the drivers to the 126 terminals. All worked well. About that time my medical issues distracted me from following up any further. When I started to revive my CNC router I decided to try the 134 again in hopes of reducing the amount of cabling inside the control box. It appears that the #3 axis has no output. I checked the ribbon cable and it appears good. I tried re-seating the 134 with the same results. Is there a way to test the ribbon connector on the 126 and/or the 134 to isolate the problem?

Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-126 Irratic power

I have a PMDX-126/PMDX-107 setup that was working using a parallel port. I had some health issues and the system sat dormant for almost a year. I just upgraded my CNC PC to Windows 10 and decided to finally install my ESS and get things going again. When I powered up the control box the PMDX-126 started clicking and the LEDs would all flash on and off several times then go dark then start flashing all over again. If I had motors hooked up they would jump and stutter. This was with out changing any thing and no PC connected. The power to the mains connectors (set to 230v) appears to be jumping all over the place. If I disconnect the mains to the PMDX-126 the 240v reads stable at the terminal block. Has my PMDX-126 died? Hardly had time to break it in. Just finished building the CNC router table and control box when I had to set it aside while I dealt with cancer treatments. I guess my next move would be to completely disconnect the PMDX-126 and try and test it somehow.

Any helpful hints?

Thanks,

Zeke
