Another C11G spindle Control issue..
« on: March 26, 2019, 09:27:24 PM »
I am hoping someone can shed some light on this. Just upgraded to the C11G...
I have everything else on this board working... BUT NO SPINDLE.
I have done just about everything...

I have a 12v supply feeding the 12volt analogue input. I have used the XML downloaded from CNC4PC. All I get out of the analogue out us like 700 MV ...

Has anyone got this working.. getting very frustrated..
Thanks

The default profile from CNC4PC I think assumes that the spindle will be controlled using Pulse and DIR method.
I don't know why you want the analog 0-10V since you did not say whether you are using a VFD inverter or not and have not named the brand and model.

Anyway, I am showing you how you can get 0-10V - just follow my 2 uploaded attachments.

Thanks for the response...
I have it setup as a pmw but I had a higher frequency than that. So tomorrow I am going to try your settings.
The weird thing about this board is ..
I am using a PC power supply since I gutted an old rack mount pc. I have one of the 5v outs to power the C11.
So I have a complete separate 12v supply. But whenever I connect the wire to the 12v input on of the relays just humming..
Even if that 12v supply us not plugged into 120v.
Now if I use one of the 12v outs of the pc supply it does not humming
But I get no more than about 300mv out of the 0-10 out.

And all I am doing is driving a DC motor. So just replacing the pot on the Harbour Freight mill.
I don't have a VFD...

For DC motor to be able to be controlled by MACH3
you need something like

So how do I drive that card from the C11

Please download the manual for C11G.

If you can get Mach3 to change analogue voltage from 0 to 10,
using M3 SNNNN command, you can wire the 0 to 10 volts between the ground and the wiper of the Potentiometer - if you already have a speed controller with Potentiometer.

e.g. M3 S24000 gives 10V
and
M3 S0 gives 0V

Yea thats the issue. I am getting like 30 mv out which ain't going to drive the motor. But Artuio says the light on pin 14 should get dimmer as speed goes down and get brighter as speed goes up. This is working so looks like I got the software correct. Just no DC voltage.

Spindle Pin 14 - did you tick active low or not?

The 0 to 10 Volts must be measured between 0-10V connector and "Analogue ground" beside it (which is not the same (nor connected) to digital common ground.

(Or try to follow page 9 and 10 of c11G manual attached)
