Whilst working on the ACAD for the wiring I finally think I know something.

Being your basic gearhead +12v on the battery is hot, -12v is ground.  So when I see -12v, GND, and SHEILD, it all means connect to da frame.

Now I am beginning to see that's WRONG.

Back to the spagetti bowl

Someone hurry and tell me if I'm still fecked up, before I get this all rewired.

Got the power supply wiring redone.

Now the X axis that is powerd drifts. kicks the Pixies out. 

Changed the polarity as Darek suggested...........still drifts.

I'll put together a wiring diagram of my spagetti bowl and post it in a day or two.

Talked to Ed @ cncbuildingblocks.  Aparently I have the power to the Pixies wired wrong.

Sort that out & see how it goes.

change the polarity of the command signal. You are probably sending it to ground now.

How to do that?

Ashby

EDIT:  Figured that out.  Swapped ref+ and ref-
         That did it.
         Now when I power up, X runs away
         Switched A and B encoder inputs on the BO board, still runs away.

The good news is that all the magic smoke is still in place.

Got all 3 plus limit switches wired.  Installed the Darlington Switch.  Haven't put
the wires for the minus switches in place yet.  I don't understand how, with
only one spot on the BO board for limit switch input, is Mach going to process
info from plus and minus switches from one input.

I have 3 power supplies, one for BO board, one for Pixies, and one for spindle
control board.

When I turn on the juice to the power supplies the drives come up, and the PLC
comes up.  The VFD for the spindle doesn't light up.  Y and Z drives disconnected, so playing with X.  As soon as the X
drive is enabled the servo motor starts drifting.  This kicks the Pixies into
defaut.  I did plug the Y drive in to see if it behaved the same, it did.
Can't tune the Pixies in default, they need to be communicating with the
motors.  Same story with PC/Mach on or off.

Maybe I missed something in Mach settings   Don't think so, since I get the
same problem when the PC isn't on.

I have called Servo Dynamics to see if they will send me an alignment
procedure for the drives.

First item on my todo list, get transistor.
Go to local electronics supply store.
Counter man has NTE book 2005.  N2074 not listed.
Couner man says "here you look thru the book, see what you need"
It's all greek to me.
Go to NTE website, enter ULN2074 in search function.
Result = Sorry, no parts were found for ULN2074
Google finds a chip, needs a socket.
From what I understand, I need a gimmick with three wires.  Base, Collector, and Emitter.
Base connects to Pixie enable, collector to OUT. SVO-ON (9), emitter to 24V COM (17)

OK, off to put a bunch ov wires in place.

You sure are patient with me.

Appreciate it......Ashby

Arrgggh

The notations are too faint for my eyeballs.
Being easily confused, I need the pic too help interpret.
The BO board has one lug per axis labled LS.
I'm looking at page 14 of the PDF for the Accu-Step BO board and trying to figure out how this needs to be wired.
Disconnect 24v+ from PC board 803 and ground it....??
Connect Red (X+) AND Grey (X-) to "X" LS on BO board....?

Darek

I tried NC contact to BO board as above.  No joy.
The BO board wants to see a connection to ground broken by the limit sw.  The 24v negative from the power supply isn't connected to chassis ground.

So if I connect limit sw NC to BO board AND power supply 24v negative will that work ??

Or will that mess up PC board 803 ?

Now I'm trying to figure out my limit switches.  I have 3 per axis, all Normally Closed . On the X........ X+ & X-(24V), overtravel (servo disconnect)  My Accu-Step BO board has one lug for each axis,  Labeled "LS".  I have read the section in the Mach 3 users guide on limit switches and the documentation that comes with the BO board.  Can't see that I can use 3 per axis with what I have.  Still have to turn on coolant after I (we) get this down.

I have another printer port.  If I need another BO board I'd appreciate a recomedaton or two.  Doesn't seem that I would need anything as fancy as what I have.

Ashby

EDIT:  Could I use the XYZ minus switches as Home?
         Not disconnect, run a jumper from NC contact on switch to LS lug on BO board?
         Don't forget >>> I'm easily confused.

P.S.  Merry Christmas
       Happy New Year
       Have a nice Easter.!!
