So I had X,Y and Z working in StepConfig... until I hooked up C41 and DB9. :(

I'm getting sick of trying to figure this out.

If I don't have the C41 PWM Spindle board hooked up, and I don't have the DB9 that connects to my spindle and switches at the mill hooked up, X-Y-Z all test OK. The three axis all move as expected.

But when I've hooked up the other two, now when I click "TEST" for X there's a click in my controller box, and the LED for "Relay 2" on the C41 board lights for a split second, and then there's a second click and the LED for "Relay 1" comes on solid and stays on.... and the axis doesn't move at all.

I'm getting pretty discouraged setting this thing up. I just want it to work, and at this point, I'm wondering if I should have just left it running Mach 3.

If ANYONE has any idea about C41 boards, PLEASE respond. I just want to get using this mill, otherwise I might as well put it in the corner and use it as a big ol' paper weight.

Here's the assignments, again, for information:

17- UNUSED
GND- UNUSED
16- "DIR", C41
14- "PWM", C41
GND- "GND", C41
(16/14/GND ABOVE TO INPUT ON C41 BOARD)

2- "DIR-", X CONT KL-5056D
COM- UNUSED
3- "PUL-", X CONT KL-5056D
4- "DIR-", Y CONT KL-5056D
COM- UNUSED
5- "PUL-", Y CONT KL-5056D
6- "DIR-", Z CONT KL-5056D
COM- UNUSED
7- "PUL-", Z CONT KL-5056D
8- UNUSED

11- "GND", C41
5VOLT- "5 VOLT", C41 (11, 5 VOLT ABOVE TO POWER ON C41 BOARD)
12- "#2 ON DB9 CONNECTOR"- RED ON X LIMIT SWITCH AT MILL
5VOLT- "#5 ON DB9 CONNECTOR"
13- "#3 ON DB9 CONNECTOR"- RED ON Y LIMIT SWITCH AT MILL

15- "#4 ON DB9 CONNECTOR"- RED ON Z LIMIT SWITCH AT MILL
5VOLT- "RED", ALL + ON CONT KL-5056D'S
EN- UNUSED
5VOLT- "RED", 5 VOLT A/C POWER
GND- "BLACK", GND A/C POWER
(ABOVE 5 VOLT/GND FROM A/C POWER ADAPTER)

***PIN 6 ON DB9 TO GROUND ON PWM BOARD***(AT THE MILL THIS GOES TO A SMALL TERMINAL IN THE BOTTOM RIGHT OF THE ELECTRICAL BOARD FOR THE MILL. THERE'S A SMALL "F-" NEXT TO THIS TERMINAL?***

***PIN 7 ON DB9 TO NORMALLY OPEN ON RELAY 2 OF PWM***(AT THE MILL THIS GOES TO THE TRANSFORMER INSIDE THE ELECTRICAL BOX ON THE MILL!!)***

Was this on another thread before the c41 ( whatever that is ) and pwm board?
I am assuming that is an isolation board for the PWM spindle controller.
If i remember correctly, and as i can read here the mill works with Linuxcnc.
Sooo now i see you have pin 1 and pin 17 unused, en is also unused, but i think you have to use one of them for enable or it will not enable the drives, hence no movement. I would suggest you put pin 1 and 17 as "amplifier enable" in stepconf and tty again. Then we can move on to seting the spindle. You have also not assigned pins for relays, they must be configured.
Pictures of boards and wiring would help.

So this would be a matter of setting 1 and 17 that way in stepconfig without changing wiring at all?

I should have updated my list above. EN is now jumpered to the 5V near it.

1 and 17 are open though.

The problem is that the directions on this wiring are, from what I can tell, geared toward Mach 3.

You can find the C41 board HERE ARE CNC4PC.COM .

Here's what they say about the board:

"This card lets you control your spindle with PWM and direction signals, as if it was an axis motor. It converts the step signal into and an analog (0-10VDC). This card also has two relays that can be used to control the direction (CW/CCW) and enable the drive (On/Off)."

Here's a schematic of the board itself. I am realizing that the way it's wired is probably wrong for LinuxCNC...

And here's a better diagram that shows my C10 board and how it's wired:

And you mentioned that it might help to have a pic of the wiring in the box specifically. Here's a pic:

Don't know if this helps, but on the CNC4C page for the C41 board they have a link to info about a HAL for LinuxCNC?

cnc4pc.com/Tech_Docs/C41HALmodifications.pdf

So if I'm understanding this correctly, this board takes the 12V from the power and runs it to an output that is 0v for spindle stopped to 10v for spindle at 100% of available RPM'S.

It also uses the relays to tell the spindle to turn clockwise or counterclockwise clockwise.

I want that feature too...

So if that's the case, I need to actually wire both relays, correct?

One to turn the spindle CW, and one to turn it CCW?

So I found this tidbit about the wiring inside the controller box....

"All models can be controlled with an isolated analog reference voltage (0 -7 VDC) in lieu of the main speed potentiometer. The voltage is connected to P2 (+) and F-."

So the wiring from pins 6 and 7 in the DB9 go to the control box to bypass the dial potentiometer that manually controls the speed of the motor. (6 to "F-" on controller board, 7 to "P2" on controller board)

If anyone has any other info/suggestions please feel free to chime in.

Tommylight... any ideas mang?
