SO...update on progress....Boss won't let me change any wiring on the board yet...He is of the opinion that it worked before, so it should work now ???

I explained to him that we're not necessarily "changing" anything....only unplugging a USB and plugging a round pin in to test and he still isn't budging.  Apparently he got a hold of the previous owner and is going to get his XML file to try before he'll let me swap the power supply.  Here's the kicker....apparently he was told you can't email the XML file. LOL.  So he's going to make a special trip to get the XML via USB on Saturday.  Whatever...I'm just a penny. Lol. 

I'll update once we have the XML....I'm kind of hoping it still doesn't work out of spite.  ;D

Thanks again for the help thus far!

Ah, I understand where your going with this now.  :) Also, I just dug through my box of cables that I've been saving since the dawn of time and found a round pin 9VDC power adapter! Lol. Now I can finally tell the wife I used one out of the box. I will post my trials tomorrow. Thanks again for the help thus far!

Thanks Craig,
I'll see what I can get rounded up tomorrow to test this and I'll post my findings.

Craig,
When you say they require an enable signal, is that the setting in the Pins/Ports where you enable the axis?  If yes, I did enable them.

No problem reuelt,
Any input is appreciated.  As far as the USB power...it was working that way when we got it so it was just left that way.  Can you elaborate as to what inputs you would be referring too?  Would the E-Stop be considered an input in said case?

Craig,
Yes, it reads 7805AC.  I just found the power supply that I have and it's a 24VDC...I'm assuming that would not work for this application? 

I'll see if I can download the manual from Yako's website if we don't have the manuals in the shop (We've had all the other manuals thus far). 

The crappy part about this whole debacle is that the machine worked perfectly, before someone decided to try and license something that didn't need to be licensed. Lol.  Theoretically, I wouldn't think any software installs would hose anything up, but stranger things have happened.

Also, I did contact the previous owner of the machine and he said he MIGHT have a backup for the XML file he had on that machine.  If he does indeed have it, I'll give that a try as well and advise.

Craig,
Thanks for the quick response. Answers to your questions below.

Can you use your meter to measure some other known good voltage source? Please confirm that the leads are plugged in
to the meter to measure voltage (high impedance input) not to measure current (low impedance input).
- I am able to measure 120VAC across an outlet....I don't have anything to test 24VDC, but I'll be using my meter tomorrow on some low voltage stuff.  I'll verify
 - The leads are in the Voltage socket...not the current socket


Is it possible that the USB cable or the USB port into which it is plugged is faulty? Looking at the pic of your BoB
there is a regular DC input jack adjacent to the USB socket. Do you have a supply that could be plugged in there
to try it?
- I suppose anything is possible, but I wouldn't think so
 - I don't have a power supply that would plug into the round DC power port, but I have a power supply I could wire in to some terminals...I'll have to read through the manual...I thought I saw a couple terminals you could use in lieu of. 


It also looks like from the pic that the LEDs associated with each output are working? Is that correct? It is those
LEDs I would expect to change state when you run the MDI codes I posted earlier.
- It would appear so, but when we ran the MDI codes no lights flickered and no motors spun...only the DRO values changed. 

I notice also that you have wires running from the step/dir pins (pairs 2&3, 4&5, 6&7) but I don't see any enable
wire/wires hooked up. Can you post a pic of your stepper driver? I'm just guessing that they have an enable input
which you are not energizing.
- Picture attached for reference.

Craig,
I'm not 100% sure if I'm checking this correctly.  From what I can tell from the PMDX manual power is applied through the USB connector (J12)...when I put my meter across the USB it appears to short the BoB out....meaning all the LEDs go dark when I connect my meter.  I've attached a picture of my BoB

reuelt,
I tried both Active High and Active Low (restarting Mach after each setting change) and it doesn't make a difference.

Craig,
I had one of the CNC operators try the MDI code you provided.  No LEDs lit up on the stepper motor.  The DRO said that the motors were moving, but nothing was moving on the table. 

reuelt,
You were correct, I enabled Port 1, and entered Pin 17 for the Charge Pump output.  No dice. Still have the same results.

I will try this tomorrow and let you know what I find.
