Parallel Port breakout boards, motherboards, and dedicated accessories / Re: PMDX-134 Axis #3 doesn't work

I want to express my gratitude for the your patience and support in getting my issue resolved. I really like your products and especially your support. I received my tested boards and new cable today. I will have to wait a week to get it all installed and running - have to make a trip to Florida for my father in-laws 92 birthday - I hope I can last that long.

Again, thanks for the support!

I think I'll take you up on that. I will send you the 126, 134 and the ribbon cable.

I will email for details on shipping.

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?

So... I disconnected everything except the 126 and connected with power switch set to 230v. Voltage checked good and the 126 worked. I re-connected the VFD and all worked good. Connected the power supply and got erratic voltage again. With only the power supply connected to 230v input I get the  erratic voltage on one leg of the mains power. So, I have corrected the issue with the power supply and that has fixed the erratic behavior. Now to figure out why my 134 axis #3 does not work. That is for another topic.

Thanks for holding my hand through this issue.

Well... I pulled the 126 out of the controller and put it on the bench. Switched it to 115v power, jumpered the E-Stop. Powered up fine and looks stable. Switched it back to 230v power and wired it to 230v in the control box with nothing else connected except the E-Stop jumper. Powered up and got the erratic behavior as before. The voltage across the mains terminals varies between about 150v and 190v. I shut it down and took one leg of the 220 and a ground connected to the mains terminals - switched back to 115v power and powered it up. Works fine. Could the switch be bad?

Thanks for the reply Steve,

I haven't connected the ESS yet. And as I said this thing sat for almost a year without being turned on. I will check all the mains connections and see if I can find a loose or bad connection. I will use and external 5v for the ESS when I connect it.

I have 240v to the box to power the Toroidal power supply, PMDX-126, and a VFD. It worked well when I first put it together last year.

Other than mains connections, would the input transformer or relay (the clicking sound) cause this?

Tomorrow I will take the board out of the control box and check it out.

Thanks again for the quick reply.

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
