wiring question for G0704, swap from smooth stepper to C10 for LinuxCNC

Okay, I'm swapping to a C10 so I can use LinuxCNC.

I've got the e-stop and the step/dir from the C25 that was on the smooth stepper swapped over.

Now I need to wire from 9 pin input and the PWM.

Here's where I'm stuck:

This is the C10 that I bought:

This is what I need to hook up from the PWM board:

These wires, red black white green in the cable and then a loose black wire.

And here they are at the other end on the PWM board.

I am trying to figure out where each of the above wires need to go to on the C10 board.

I've also got a red wire that's daisy chained on my controllers that still needs a home on the C10:

The last thing I am lost on is the 9 pin that is bringing the signal from the limit switches. I asked the builder if he has any kind of a wiring diagram from these that I can use and he doesn't seem to.

I'm assuming the black in the top row is a common ground (all 3 are juntioned in pin 1 on the small board that the cable is attached to on the back of my mill?) and then the 2-3-4 (blue) seem to be the axis? I have pins for x y and z limit switches on my C10 above. Just don't know where these go. The 4th blue wire on the end is a loss. I have no idea what that's for. The bottom red and black run to the PWM board IIRC.

I'm sure these are stupid questions, but like I said, this is all new to me. I've never built or modified a mill before. I am familiar with programming and operation, but this is foreign to me.

Thanks in advance for any help!

that breakout board is not a CNC4PC C10 board !

its a chinese board that finding it did not work as expected
I reverse engineered and discovered the 74hc14 hex inverter IC did not have its positive supply pin (14)
connected to the +5V supply !

be carefull wiring the PWM board to the G0704's speed control board
the original wiring to the speed control potentiometer that now goes to the PWM circuit will be LIVE
so the low voltage power supply to the PWM circuit must not be used to power any thing else

I will post a link to a previous post with details of the breakout board when I find it

I know it's not a CNC4PC board. It's just what came up on Ebay when I searched "C10 CNC Board".

If it doesn't work I'll order a CNC4PC board.

Unless it would be easier to just order the CNC4PC board to start with...

Anyhow, the mill was up and running prior to this. Like I said, the only reason I'm swapping is to use LInuxCNC instead of Mach3.

If you can tell me where these wires assign to I can hook it up and I'll report back and tell you if it's time to order a CNC4PC board or not. ;)

assuming the breakout boards 5V supply is connected to the green terminal block near the printer port connector and not via the USB socket
connect the common red wire from the stepper driver inputs to the boards +5V supply wire as the axis terminal blocks only have 0V/GND terminals

assuming the 3 stepper driver inputs are wired to the BOB's X,Y & Z stepo & direction terminals
I'd wire the A axis outputs to the PWM boards GROUND , PWM and Direction terminals

wire the blue wires from the 9 way D-Type to the breakout boards 4 limit switch inputs in turn and the black wires to the limit switch ground terminal


I would double check the long black & red wires that you think are from the speed control boards
are not live when you have mains power on the speed control board

it depends on the speed control board you have in the milling machine

if you find the wires are live, then I would remove them from the 9 way D-type and connect them via a mains rated connector

your PWM board looks like this C41 board

For the daisy chained red wire, you need to check the stepper driver manual and find out what it is.

Pul + and Dir +

going back to post 2

I expect the speed control you have will be very like the one in this lathe
Variable speed controls - The Warco

which will make the wiring between the speed control and the PWM board live as I expect

added some details of PWM board wiring

If they were daisy chained in the pevious install then they would go to a 5v+ pin on the BOB

Makes sense, and that's where they will go. :D

Please guys, I know this is dumb, but dumb this stuff down for me. I didn't build this mill and don't know much about this hardware at all.

On the DB9 connector it would appear that the following are used:

1- ground for all 3 limit switches
2- X
3- Y
4- Z
5- ? (There's a wire in the control box, blue wire, for 5, but on the other end where it goes into the mill there doesn't seem to be anything connected to the board for 5?)
6/7- TO SPEED CONTROL BOARD
8/9- EMPTY

I get where some of this goes, but wire 5 for example.... totally lost.

I would expect wire 5 to of been an unused input to the breakout board
and intended to be used at a later date for some thing like a touch probe or
an E-stop switch , if the control box does not already have one thats in easy reach
