Re: getting the 57cnc to work with G540

Dan:

The Docs for the SuperPID seem to show it needs an opencollector drain to turn it on ..

Pin 45 may not be suitable. Id use either the relay.. OR OC1, just as the default spindle was set up for.
Youd connect your RUN wire from the super PID just to OC1 on the board. This also means youd see the LED to show
if its on or off...

OK I will try that

DanL · Post by **DanL** » Sat Feb 27, 2016 10:38 am

it worked

DanL · Post by **DanL** » Sat Feb 27, 2016 10:57 am

it turn's on or off, but run's at full noise.

now for the pwm control on pin 20 pwm 2 do I put the changes into the Library MotionIO at the bottom it has Pokeys1.SetPWM( channel, duty); so channel will be 2 duty not sure.

and Pokeys1.SetPWM( period ); period would be 20ms

I got 20 from the pokeys config if I set 20ms in the pwm bit it has that it is  50.00 Hz

I will try this anyway and take a guess at what duty should be

So i did do the changes the pwm 

also the pwm just stays at 5.02 vdc, with the spindle on or off, on oc1. I have read through all post's looking for where to set the pwm. I am a bit lost I will play more to see if I can find what to set, but I need help.

Dan
After looking at the Super PID stuff you are going to need to follow several of the post I was working on.

You need to set up the circuit detailed here

You can read up on the circuit here
That is where I got the schematic from.

You will also need to map the spindle speed to the PWM value not sure if Art has anything in place yet for that.
Click on the quote link for help with that

I fixed the PWM being at 5vdc it was the - from OC1 I put it to common and that came good pwm is now working in pokeys.
spindle on/off works.
I will have a look at your stuff again, at a guess I would add it to the library where the spindle control is, or does it need it's own Library. I will just play and see how I get on.
making these mistakes and you boys just pointing and hinting, and Art or anyone giving the idea of how to do it is good

Can you post a rough sketch of what you did?
I am very interested in that.

Thank you sir

GlennD I just looked at your pick for the circuit, because of the type of dyslexia, it means nothing to me. I get the idea tho I will draw it in fritzing what will give me the the pick

Hi Dan:

  Youve lost me a bit.
OK, we have two issues, 1) PWM control, and 2) RUN control..

1) To get PWM to run, we need to use a PWM signal the SuperPID can use. In this case your using Pin20, correct? SO does this work
in Pokeys? Auggie? Both?

2) Ive read up on the SuperPID, if you intend to use OC1+ to your SuperPID RUN line, and hook OC1- to the superPID
    ground, the on/off should work. Does this work OK for you in Auggie, or just in Pokeys? or Both?

  If Im understanding you, one of thses is working in both? Let us know, lets fix it one signal at a time, so we know that signal works, then
we'll finish the second. Your really close I think..

hi art
(1) I have oc1+ to run and oc1 - to ground next to the run pin it would turn the superpid on at full nacker 30,000rpm. and at the same time the pwm 2 pin 20 would be at 5vdc at the superpid.

(2) I left oc1+ in run and put oc1- to my common ground then ran a wire from common ground to the ground pin beside the run pin, with it like this it will turn off and on and the pwm pin is low .02 vdc so it runs at 5000 rpm.

I can't turn it off or on with pokey's can't work out what pin OC1 is.

when it is set up as 1 I can not change the pwm in pokeys.

when it is set up as 2 I can change the pwm in pokeys it goes from 5000 rpm to 17000 rpm 0 to 3.3 vdc.

so it's sort off working. as a test I left the pokeys open started Auggie turned the spindle on and tried to change the speed on PWM 2 pin 20 it did it for a second then when back to 5000 rpm and I had to reset everything bad idea.

I played around with the code GlennD did one of them was working sort off. I will have to go to that computer and finish the reply from there.

    This IS the correct way. In order for the pokeys signals to make sense to any device, they must share a reference, in this case..ground. SO keep
it this way.

>>I can't turn it off or on with pokey's can't work out what pin OC1 is.

    Its a pin belonging to the Pulse engine, youll find them on the right side of the pulse engine screen in Pokeys.

>>when it is set up as 2 I can change the pwm in pokeys it goes from 5000 rpm to 17000 rpm 0 to 3.3 vdc.

   OK, so the pokeys changes the speed, and I suspect also turns it on and off when you use the engine screen.

>>so it's sort off working. as a test I left the pokeys open started Auggie turned the spindle on and tried to change the speed on PWM 2 pin 20 it did it for a second then when back to 5000 rpm and I had to reset everythin g bad idea.

  lol, yeah, never do that. Run Auggie OR pokeys, never both..

 All we need to do is get your PWM working, thats all. I dont have it attached to spindle speed yet I dont think.. BUT..lets try
doing it in Script. Execute an M3 and it should turn on... since OC1 is working, so lets try in the scripter to make the pwm change..

in the scripter or ScriptMDI, enter

m = Motion();
m.SetPWMDuty( 2, 50 );

Run that and see if speed is now 50%.. Try m.SetPWMDuty(2, 10); and see if its now 10%..

Let me know what it does..

that don't work Art

I tried as well
 
m = Motion();
m.SetPWMDuty_1( 2, 50 );
