Hello,

I have some doubts about the functioning of my chuck.

I have a pedal with a siwtch
a solenoid

1. how program with press the pedal you open or close the jaws?
2. how to program the pedal is disabled when spindle on?
3. how programmed to work the jaws. out or in.?

any help is valuable.

thanks

I see you have posted now 162 times.
These are pretty general questions.

have you read the manual ?
HAL is what is used to program all these.
classicladder is probably an easy way to do the logic.

If you want specific answers, ask specific questions.

You can do this using a HAL "near" component and the "and2" component with the inputs as the pedal switch and the spindle speed being near zero (setting it to _exactly_ zero is likely to be too sensitive, for example closing the chuck again if you move the spindle while loading a part. That could hurt.

Cmorley.

In no time I wanted to bother. is already 162 times should be more adept at linuxcnc, but the fact is that even I'm not. I'm missing a lot. I think that he gets to 2000 and still will not know much.

My question is the following. view the images.

Not a lot of electronics or hydraulics, much less HAL.

I have a (JAWS CHUCK FOOT SWITCH)
and a (double selenoid valve)

I do not understand how to connect the (chuck jaws foot switch) and the (double selenoid valve)
the foot has only one connection and I have two selenoid. as connected first of all to my card and then how could 7i64 run with HAL.

Thank you very much. I hope soon to be no trouble, however that just work to start, as you have done with me.

again thanks.

Any time you wish to connect two different inputs to the same output you can use the or2 component.

linuxcnc.org/docs/html/man/man9/or2.9.html

The or2 takes two input bits and has one output bit. If either input bit is on then the output is on.

I think that would be wrong in this case.
We don't want the chuck opening of the spindle is stopped _or_ the pedal is pressed. That would be very inconvenient. :-)

Yes you would want a conditional in there as well to make sure the spindle is stopped before opening the chuck and make sure the chuck is closed before allowing the spindle to turn.

I did not understand?

John's idea is not correct?

what would be the best solution?

Jlviloria:

My words might have seemed heavy hitting - I apologize.
It's not that helping you is a bother nor that you have messaged many times.

It's just your question was very vague - so we can only give you a vague answer.
When asking a question give as much important information as you can.

other wise it takes us three questions just for us to figure out how to answer what you really want to know :)

But don't hesitate to ask questions - it does help to look in the manual first
it gets you in the habit of using it as a reference and you find new things all the time !
