Man Hood,
   guys like you make me feel like such a idiot. Thanks for getting the pic on here.I stated up front in my opening post I'm NOT a computer,electronics or internet communication wiz & I guess the fact I can't even get a pic in a post proves it.I tried a right click on the pic,(seems like I remember an option like "resize"in win XP ?). But I didn't see any option to resize, Hell i don't even know why they are BIG in the first place!When you say you have taken a screenshot of it,got it to show in post as a thumbnail at a reasonable resolution,phew! sailed right over my head?I can't keep asking for help,pretty soon you'll be expecting me to ask how to tie my shoes!!
    In the pic you'll notice I only have 1 encoder cable made at this point(Z axis on far right)The r  0  on the display indicates the drive is ready to display rpm's.I can turn the servo motor shaft between my fingers and get a reading so I'm pretty confident the cable is made correctly.The X & Y are flashing Err  22 indicating an encoder or cable problem cause I don't have the cables made yet.
    After our correspondence yesterday I believe we think I don't have a power supply connected for signal control. I kinda thought that myself when I read the manual but I also thought to myself "how can I have a readout on the drive and an encoder that seems to be working if the control has no power?" But you have me confident & convinced of what I need to redo as soon as I can get hold of some shielded cable with enough conductors.I need to backtrack this thread and get a list of exactly what I need where & where(those cw &ccw inhibs,etc).
    Thanks for getting a pic up for me,(proving it's easy IF ya know how).Now I need to search "screenshot & thumbnail" & see iffin' I can get me some learn'!!
    THANKS HOOD, Rick

Yes Hood,
    I'm really having a problem here with pics. I've tried the attach & brouse,renamed the file each time. Forum says I already sent the post but nothing is showing up here, not even the text. I don't seem to be getting the errorr code anymore, I did some more searching on that before work this morning & found it to be a known windows 7 bug when downloading pics & video from certain devices. Was directed to microsoft site to download & install "windows essentials" which is supposed to be the bug fix,which I did.I took the pics with my ole'lady's camera,(first time I ever used it),they look fine in my 'puter,maybe I need to take them over and try all over again after having installed the fix?

Well folks,
    Just thought I'd let you know I've been trying like heck to post some pics of my project with no luck. >:( I finally saw something in lower taskbar about an error 0X80010108 preventing photo or video from displaying? They display fine on my computer, just can't get them into a post. ???Googled the error code, said to do a syatem restore at the latest restore point.This is a win 7 box,about 15 months old & I've never done a system restore on this machine but started it anyway to see if it would fix the problem. Turns out the latest restore point was like 6:30 am this morning & said something about a windows update at that time. ???I don't know but maybe microsuck causing the problem?Whatever I did the system restore at that point,tried to get a pic into a post & same result as before,same error code.
    This had/has been a fun & productive sunday off work thanks to this forum,Hood & others.But time to prep for another workweek of drugdery now.I will be working on the rewire of the servo drives as time permits & will report back here on progress when there is some.Will also be trying to SHOW my progress if & when I can.
                 Thanks to all,    Rick

Going to try some pics, I had 4 attached to the previous post & it just would not happen. Any tips/suggestions on the best way to get them here?

I second the Hood for president Brett! When I was doing some research on the connectors of CN I/F I found some called them sub D 36, centronics mini D 36 & I also found them called HP 36. Seems some HP printers used this connector and I found printer cables on-line that are this sub D 36 on one end & 25 DB on the other,pretty cheap,$8.00 or so apiece. Could I get away with getting some of these printer cables, cutting off the DB25 and bringing out the wires for connection to BOB ? I was afraid that seeing how they are 25 on one end & 36 on the other (the end I need)maybe wires aren't connected to all 36 pins or maybe something is jumpered internally which would make them unusable for my needs. What do you guys think, worth taking a chance?

OK Hood,
    It's official, YOUR MY HERO BUDDY !! Sorry, couldn't help myself. ;D At this point I'm happy that all my problems weren't of my own making. With all the help you've offered today I'm now at a point where I have work to do REDOING the CN I/F cables from BOB to drives. That's going to take awhile, hope I can still get by with the cabling I have, it's shielded 3 TP (6 conductors + shield). Soldering these cables is a pain for an old guy with not so great eyes anymore & arthritic hands. Also the machine itself is half done at best so even if the motors were ready to go I don't have a machine ready for them yet.
    I was practicing my manual machining skills on building the machine itself until winter came to Iowa.When it did it's just too cold for working out in my homeshop & the shop is too drafty and uninsulated to heat in winter(I just can't afford it). So Christmas eve was my last day in the shop till winter is over. Christmas day I moved my focus to the basement of my house where I decided to start work on the computer & electronics end of the project. It's getting close to spring here (still had snow last week though). I'm hoping to have motors jogging under Mach control before going back to the shop in spring to finish the machine.
    I'm thinking I will try to post some pics of my control system mock-up and maybe some of what I have done machine building wise before I disappear for awhile so you can see I really am trying to work toward having my own DIY cnc at home. When & if I do disappear for a while please don't think your much appreciated efforts today were a waste of your time, I will follow your suggestions on wiring connector CN I/F and report back here on my progress.
    Thank You Very Much Hood(& Dickeybird),   Rick

P.S. I'm still not going to badmouth the e-bay seller till I have this set-up working but BUYER  BEWARE if he says instructions and block diagram for Mach 3 included!

I just noticed an error in my last post, I have the 24v connected to pin 12 (not 12v as I stated in previous post).

Well Hood,
    Even though I didn't get this stuff to work on my own I am getting some satisfaction in the fact that you seem to be seeing some of the same problems I did. I do have the 12v connected to pin 12 because that's the way I read the supplied instructions as well.The first thing tried was to jumper 28-29-30 while leaving the other wiring as per the supplied instructions,nothing happened good or bad (at least not that I know of). When that didn't work I removed the jumpers and the next thing I tried was feeding 24 vdc to 28 & 11 (11+  28-) while leaving the other wiring as per the supplied instructions,still nothing good or bad (I hope). That's all the farther I wanted to experiment on my own for fear of cooking something I had to save my pennies up for a long time to get in the first place. That's when I came to the Mach support forum looking for help.Have I mentioned I REALLY APPRECIATE your help? Well I sure enough do Hood. I'm thinking it's time to pitch the worthless supplied instructions & redo things how you suggest if you'd be so kind,PLEASE
       Thank You,   Rick

Yes Hood, the output from my 24 vdc power supply is connected to BOB at connector next to the parallel cable connector. I have used my VOM to check powersupply output at the BOB, 24 vdc as it should be. When I check between 24v & GND at connection from BOB to cable CN I/F it's 21.4 vdc (BOB must be regulating it down?). Anyway the way I read it the drive should be happy anywhere between 12 & 24 vdc so I didn't think that was a problem.BTW when I check between 24v & GND at axis connection point the polarity is correct even though the BOB instructions say polarity doesn't matter at the input point.
